Stories of the Week

Salesman Sam presented his
credentials.

“I’m the best man in this
business,” he proved to a small
manufacturer. “Give me a
chance with your line and I'll
up your volume plenty.”

“Maybe so, maybe so,” groan-
ed the owner. “But anyone I
hire has to start from the
bottom. First you gotta be my
partner.”

Two acquaintances from Chi-
cago met accidentally in Miami.

“Yasss, dearie,” fat-catted the
first woman, “I’m down here for
five months. And you?”

“Three weeks.”

“Three weeks ? Whatsa
matta? Ain’t your husband
working?”

Watch Your Waistline!

Nearly every scientist one
meets these days is guarding his
health. Likewise, those busi-
nessmen who have access to re-
search laboratories, and have
glimpsed what’s going on there-
in. Why are they watching their
waistlines, taking their vitamin
pills, ete? They want to live to
see the 70 wonders of the World.
(For 70 one might easily sub-
stitute 700, from what we have
heard. )

You see, we are on the verge
of scientific crash-throughs
which stagger the imagination.
Within the next dozen years our
whole life, as we know it today,
could be vastly different. And
infinitely more exciting.

Take that matter of health,
itself. Any man _ reasonably
young, who does survive the
next dozen years stands a pretty
fair chance to reach 100. In
fact, some medical scientists
foresee a lifespan of 150 as be-
ing normal for humans after the
great killer diseases have been
eradicated.

We are well on the way to-
ward that goal. Go down the
list of diseases which knocked
off our ancestors—typhoid, pla-
gue, tuberculosis, malaria, small-
pox, diabetes—all are under
control now. Looks like we have
dread polio licked also. It prob-

Tremendous Growth Possibilities
Of Commercial Refrigeration
Based on ‘Leisure’ Foods

Until fairly recently commercial refrigeration has been
a nice, quiet, comfortable business. In the main it has been
dominated by relatively middle-size firms which specialized
on such refrigerated products as:

Walk-in coolers
Reach-in coolers

Glassed-in food display cases

Open-front frozen food cases

Milk coolers and dairy refrigerators

Water and beverage coolers

Ice-cube-makers for bars, restaurants, hotels, and clubs

Ice cream cabinets and soda fountains

Miscellaneous items like florist and pharmaceutical
refrigerators, dehumidifiers, refrigerated trucks, vending
machines, and special applications.

With the exception of the seventh item (automatic ice

Typhoon Unveils
Low-Cost Heat
Pump, *57 Line

TAMPA, Fla.—Typhoon Heat
Pump Co. here, a division of
Hupp Corp., has announced a

new economy model “Prop-R-
Temp” heat pump (for year-
round heating and _ cooling)

which, the company claims, can
be centrally installed for as low
as $1,000.

The new complete line includes
water-to-air, air-to-air, and
water-to-water units for residen-
tial and commercial use, in sizes
up to 40 tons.

It was unveiled at the firm’s
fifth annual heat pump school
at the Tides hotel, St. Peters-
burg Beach, Fla. Over 100 deal-
ers, sales representatives, and
utility executives attended.

Harry W. Jobes, general man-
ager, stated that all three types
of package units are already in

production.

Silco Products To Move
To Conditioned S.C. Plant,
Begin Operations Soon

MINNEAPOLIS—Silco Prod-
ucts, Inc. will close down its
plant here Feb. 15 and move its
entire operation to a new, mod-
ern, air conditioned plant at
Fountain Inn, S. C., George E.
Cook, president, announced re-
cently.

“By moving the factory by
departments, we hope actually
to lose very little time and ex-
pect to be ready for full opera-
tion the early part of March,”
Cook stated.

“We know that there will be
a period during our moving ac-
tivity when we will be in no
position to ship anything,” he
continued. “We are trying to
make this as short and painless
as possible. We have laid our
plans accordingly by manufac-
turing ahead of schedule.”

AsHAE Local Airs
Contractor Woes,
Industry Problems

ATLANTA—Problems arising
from conflicts among the differ-
ent segments of the industry—
consulting engineers, manufac-
turers’ agents, jobbers, and
contractors—are being aired at
a series of programs currently
conducted by the local chapter
of the American Society of
Heating & Air-Conditioning En-
gineers.

The series, which features
the various industry segments
in panel discussions, was devel-
oped by Edward W. Klein, Jr.,
chapter program chairman. Dis-
cussion is sparked by anony-
mous questions, submitted in
advance, and controversy is wel-
comed.,

It’s anybody’s guess what the
meetings will accomplish. But
Klein feels that “we might find
a better way of living with the
problems in the industry.”

Among these problems, it has
been noted, are dwindling pro-
fits (despite a high volume of
business) and fierce price com-
petition.

At a meeting featuring man-
ufacturers’ agents, two areas of
conflict were brought out: be-
tween the agents and consulting
engineers, and between agents

and jobbers.

Offers Free Income Tax Aid
With Major Appliance

MOULTRIE, Ga.—Dixie TV
& Radio Service came up with
a timely promotion. It offered
to figure anyone’s income tax
with the purchase of a major
appliance.

An ad being carried over radio
station WMTM says:

“Dixie TV & Radio Service is
offering free tax consultation
and income tax form figuring
with the purchase of any major
appliance, such as _ freezers,
washers, TV sets, and radios,
between now and April 15.”

Shipments Up
40% for 10 Mos.

WASHINGTON, D. C.—Man-
ufacturers’ shipments of com-
pressor bodies used in air con-
ditioning and refrigeration units
were up almost 40% during the
first 10 months of 1956, as com-
pared with the same period of
1955, it is reported by Geo. S.
Jones, Jr., managing director
of the Air-Conditioning & Re-
frigeration Institute.

The figures, which do not in-
clude compressors used in house-
hold refrigerators, were com-
piled from reports made to ARI
by manufacturers whose output
is estimated to represent in ex-
cess of 90% of the industry, he
said.

Sees Outdoor
Egg Vendors

Upping Sales

BLACKSBURG, Va. — Egg
vending machines may not be
uncommon within the next few
years, says D. D. Bragg, associ-
ate extension poultry specialist
at Virginia Polytechnic Insti-
tute.

That’s one of the changes he
predicts for the poultry and egg
industry. He says the vending
machines, with controlled tem-
perature and humidity, might be
located outside large stores for
the customers’ convenience and
for Sunday sales, and even at
roadside stands on _ heavily-
traveled highways.

Bragg sees a “growing trend
toward quality control of shell
eggs through controlled pro-

Servel Reduces
Net Loss In 56

EVANSVILLE, Ind.—In its
second year under new manage-
ment, Servel, Inc. substantially
reduced its operating loss, ac-
cording to the annual report to
stockholders.

The net loss of the company
for the fiscal year ended Oct.
31, 1956, amounted to $1,833,-

cording to Louis Ruthenberg,
board chairman, and Duncan C.
Menzies, president, totaled $42,-
665,371, as compared with $58,-

General Controls Acquires Chicago
Manufacturer of Counting Devices

GLENDALE, Calif. — Share-
holder approval has been ob-
tained for the merging of Pro-
duction Instrument Co., Chica-
go, manufacturer of mechanical
and electric counting devices,
with General Controls Co. here,
it was jointly announced by
William A. Ray, president of the
automatic controls manufactur-
ing firm, and Joseph F. Visin,
president of the Chicago com-
pany.

The transaction involves the
purchase of all assets of the
counter manufacturer in return
for an undisclosed amount of
General Controls common stock.

“Production Instrument’s 25-
year record and excellent ac-
ceptance of its broad product
line. will permit us to operate
this new activity as a separate
division,” Ray stated. ‘‘Further-

more, counting devices are com-
patible with the General Con-
trols line of automatic indus-
trial controls and will material-
ly strengthen the combined op-
erations in the field of automa-
tion.”

It is planned to market the
product line of the new divi-
sion through the existing dis-
tribution pattern of Production
Instrument Co. in conjunction
with General Controls’ 42
branch offices.

Sutton Adds toe Plant

WICHITA, Kan. — Construc-
tion is under way on an 18,000-
sq. ft. addition to the O. A. Sut-
ton Corp. warehouse facilities
here. Officials said the new fa-
cility will be used for receiving
incoming parts for air condi-
tioning equipment production.

Firm Cuts Private Brand
Appliance Prices Up to 12%

MINNEAPOLIS — Expecting
a “much sharper competitive”
market this year, Gamble-
Skogmo, Inc. cut retail prices as
much as 12% on its private
brand appliances, according to
a company spokesman.

About 1,500 items have been
added to the firm’s lines. Among
these is a 15-cu. ft. combination
refrigerator-freezer to retail at
$399, it was further announc-
ed.
The company will replace its
brand with the full line of Gib-
son air conditioners, it was ex-
plained. Prices on these units
will also be competitive, compar-
ing with prices on private
brand merchandise. Margins of
both dealer and company will
be affected by these cuts, it was
said, but “in the long run it
should prove a profitable ven-
ture,” the spokesman comment-
ed.

May Underwrite Explanatory Brochure

9 Meet To Interest Detroit Youth In
Conditioning, Refrigeration Careers

DETROIT—A first step in an
effort to interest Detroit youths
in air conditioning and refrig-
eration as a career was taken
by an informal group of nine
men representing all elements of
the industry here recently.

They agreed to study the
cost of producing a vocational
guidance brochure telling of the
opportunities offered by this in-
dustry. The brochure would be
placed in the hands of all voca-
tional guidance counsellors at
the eighth and ninth grade
levels in the city school system.

The action was taken after
Carl Turnquist, head of the air
conditioning and ‘refrigeration
department at Cass Technical
High school, told the group that
out of 3,400 students attending

cents

When you buy a low

temperature system and
check the TOTAL costs of both
the low and high side,
you'll be pleased to find that

THERMOBANK provides the only positive re-
evaporator with ample heat supply.

THERMOBANK completely protects the com-
pressor — no liquid refrigerant to the com-
pressor, no oil foaming, no motor overload.

THERMOBANK reduces electricity costs, re-
duces compressor requirements, and elimi-
nates electric heaters.

at school, only 16 were studying
refrigeration.

The most that ever took the
course was 43, and this number
has been dwindling, he said.

Says Interest Lack
Due to Not Knowing
Opportunities Exist

Turnquist declared that he be-
lieved that this lack of inter-
est in refrigeration on the part
of young people was due pri-
marily to the fact that they do
not know that such an industry
exists or what opportunities it
offers.

They need to get this infor-
mation, he urged, before they
enter high school. Then they
will have the opportunity to

» select the courses they need.

The industry must offer op-
portunity, he observed, for 250
adult students to keep the
classroom busy five nights a
week, Short-term schools offered
by manufacturers and distribu-
tors are always crowded, he
added.

“With the increased emphasis
on science in recent years,
more and more students are
turning to this field,” Turnquist
declared. “The fact that out of
550 science students at Cass
Tech, 160 are honor students
indicates that the brains of our
youth are going to science
these days.”

But, he noted, the air condi-
tioning and refrigeration indus-
try is not getting its share.

“Only three out of every
20,000 students taking higher
education in Detroit are study-
ing air conditioning and refrig-
eration,” he asserted.

Agree Promotion
Should Be Supported
By the Industry

The group agreed that some-
thing should be done about this
situation. Consensus was that a
promotional project of this sort
should have industry-wide sup-
port. The group decided to de-
termine what costs would be in-
volved and then to solicit the
necessary financial backing.

Wholesaler representatives
felt certain that their com-
panies would support such a
project and members of ASRE,
RSES, and RACCA, expressed
faith that members of their
local group would help as indi-
viduals.

Ray Lee of Lee Equipment Co.
called the meeting. It was at-
tended by Jack Barager of
George L. Johnston Co., Jack
Winslow of Effective Tempera-
ture Control; Boyd Kitts of
Stroh Brewery, Mike Sarzynski
of Young Supply Co., Jim Raws-
thorne of J. George Fischer &
Sons, Inc., George Poggen of
Frigidaire Sales Corp., Leonard
Bedard of Ford hospital, and
Turnquist.

Show in Chicago, Feb. 25
through March 1.

Last year’s sessions were held
in Beverly Hills. Basis for the
switch is that key company
sales and engineering person-
nel will be manning the firm’s
triple-booth floor display at the
show, it was indicated. Also, a
majority of factory representa-
tives of the air conditioning
equipment manufacturer have
said they and their staffs will at-
tend the show.

Themed “Drayer-Hanson Pro-
duct Fiesta,” the company’s
showcase will “allow for product
discussion and comparison,” it
was stated.

Parent company National-
U. S. Radiator Corp. and Unar-
co, another division, will have
booths adjacent to D-H’s dis-

play.

National Electrical
Week Promotion Seen

Having ‘Huge Impact’

NEW YORK CITY—The Na-
tional Electrical Week observ-
ance Feb. 10-16 will “come of
age” as a major all-industry
educational and promotion
event, Merrill E. Skinner, chair-
man, said in a report from the
N.E.W. Committee.

“With the tremendous back-
drop being provided by network
television, radio, and publica-
tion advertising, and with all
the reports we have on vigor-
ous state and local activities, we
are certain that National Elec-
trical Week will have an out-
standing cumulative impact
throughout the United States
and Canada,” Skinner said.

Seay To Emphasize
Developments Due

NEW YORK CITY—Coming
electrical developments that will
affect everyone living in the
second half of the 20th century

zation of women whose business
occupations are connected with
all branches of the industry
and allied fields.

Joint Environmental Control

Institute To Classify, Integrate Data
On Heating, Cooling Health Safeguards

LOS ANGELES—Plans for a
joint Institute on Environmental
Control by the Institute of Heat-
ing & Air Conditioning Indus-
tries and the University of Cali-
fornia at Los Angeles were
announced by Managing Direc-
tor R. E. (Rudie) Harkens.

The institute, “which will be-
gin to classify and integrate the
vast amount of field and labora-
tory data on man’s struggle to
safeguard his health and com-
fort through heating and air
conditioning,”’ will be held next
fall on the UCLA campus.

It is being worked out as part
of the Stamp Plan public rela-
tions program under direction of
Joe Alvin, newly-appointed pub-
lic relations director of the
institute, and under the super-

vision of William L. Hoyt, chair-
man of the standards committee
appointed for 1957 by President
Robert N. Hall.

The plan for the institute has
been accepted in principle by
Dr. L. M. K. Boelter, dean of
the UCLA School of Engineer-
ing, who has been invited to
deliver the keynote address at
the opening session.

“This is one of the most
progressive steps ever under-
taken by the industry for up-
grading and_ self-improvement
through higher standards,” Har-
kens said.

“We want it to be a common
meeting ground for the vast and
immensely valuable laboratory
data developed by UCLA schol-
ars and engineers, and the

Air Conditioning & Refrigeration News, February 11, 1957

equally valuable field experience
of the industry,” Boelter con-
tinued.

Upon approval of the agenda
and plan for the institute by the
board of directors of IHACTI,

arkens said, invitations will be
extended to the National Warm
Air Heating & Air Conditioning
Association, the American Gas
Association, and the Pacific
Coast Gas Association, as well
as other qualified groups, to
participate in the UCLA discus-
sions.

UCLA, on the other hand, will
make available its top research
scientists who have been prob-
ing into human reaction to en-
vironmental factors in every
field, including aeronautics and
solar energy, a spokesman ex-
plained.

A public announcement of the
plans will be made as soon as
joint committees are formed by
the university and the institute
to outline and program the
agenda.

N. J. Covers Cooling
In New Building Code

TRENTON, N. J.—The State
Conservation Dept. announced
that the standard building code
of New Jersey has been ex-
panded to cover air condition-
ing, electrical equipment, and
elevators.

Three new sections of the
code cover elevators, motor
stairways, dumbwaiters, and
conveyor equipment, air condi-
tioning, mechanical ventilation
and refrigeration, and electrical
equipment and wiring.

nation is scheduled for next
May. To be third largest struc-
ture in Dallas, it will contain
432,000 sq. ft. of space and pro-
vide parking space for 3,000
cars.

Air Conditioning & Refrigeration News, February 11, 1957

Remote or over 5-Ton Refrigeration
Units In Milwaukee Now Must Pay Fee

MILWAUKEE—A new refrig-
eration code which adopts the
Wisconsin State Refrigeration
Code by reference is now in ef-
fect here, according to the De-
partment of Building Inspection
and Safety Engineering.

The former code covered only
multiple evaporator systems, it
was pointed out. The new one
“is quite different.”

In part, the new code says
that all remote refrigeration
systems “irrespective of ton-
nage” and all unit refrigeration
systems “in excess of 5 tons”
shall be subject to a permit and
the inspection regulations cited.

When any refrigeration work
for which a permit has been
issued “is not started within
six months from the date of the
issuance of the permit,” or if
there is cessation of such work

which has been started “of
more than six months,” then
said permit shall lapse “and be
void, and no refrigeration work
shall be begun or resumed until
a new permit is obtained” and
the fees are paid.

Fees for permits required by
this code for installation of any
refrigeration system “shall be at
a rate of $1 per horsepower with
a minimum permit fee of $3 and
a maximum of $25.”

Each_ refrigeration system
within the scope of this code, ex-
cept “those systems of the her-
metically sealed type,’’ shall be
provided with a “durable and
legible sign’ showing the name
of the refrigerant used in the
system “in black letters %¢-in.
minimum height on a yellow
background” except that this
color combination “shall not be

Air Conditioning

required where a different color
code is already in use.’

The sign shall be “permanent-
ly attached to the compressor,
liquid receiver, or charging
valve” and shall be in full view

from each location of such
equipment, otherwise “addi-

tional signs shall be provided.”

Main refrigerant line valves
and the main compressor discon-
nect switch on all remote sys-
tems “shall be identified by
name with a sign of the same
size and type” as aforemen-
tioned. Direction of flow arrows
and in-and-out designations
shall be used wherever practical
and valves or other equipment
so marked shall not be installed
“in other than the indicated
direction of flow.”

Where refrigeration equip-
ment is housed in a separate
room, “such rooms shall be legi-
bly marked ‘Refrigeration
Equipment Room’ on the en-
trance doors.”

10-Ton Central Unit Leads Forston’s

’57 Line; Offers New Auto Conditioner

HOUSTON, Texas — Newest
addition to the Forston Co. air
conditioning line are 10-ton cen-
tral units, air handling units,
and a new-model automotive air
conditioner, the company an-
nounced.

The 1957 line of air-cooled
central air conditioners consists
of 2, 3, 5, 7%, and 10-ton re-
mote type systems. These are
claimed to have a wide range of
uses when supplemented with
new evaporator assemblies and
air handling units offering
adaptability to various installa-
tions for residential, commer-
cial, and industrial purposes.

Forston 2, 3, and 5-ton units
are equipped with “F-22” com-
pressors, available in single or
three-phase. The 744 and 10-ton
models are equipped with “F-22”

compressors offered in three-
phase.

Multiples of the units are
practical, the company said,
where required capacities are
greater than 10 tons. “All types
of zone cooling can be accom-
plished,” it was added.

Also included in the line are
1 and 2-ton window air condi-
tioners. Flush mounting, four-
way direction air flow louvers,
and thermostatic control are
features.

“A glamorous touch is added
to automotive air conditioners
with our ‘Golden Accent’ units,”
the company declared.

Model A 37 is equipped with
new “Magnet-Louvers”’ with con-
trol panel centered for con-
venience. It is said to offer
“instant” cooling and controlled

air circulation. A choice of cabi-
net finishes is available, but the
Golden Accent is featured.

The line continues to include
compact dash and trunk mount-
ed models with thermostatically
controlled magnetic clutch.

Pratt Hospital To
Be Air Conditioned

PRATT, Kan.—A Ford Foun-
dation check for $11,600, first
half of a $23,200 grant to the
Pratt County hospital, will be
used to air condition the insti-
tution before the next “hot”
season.

The Sisters of St. Joseph op-
erate the hospital and their plan
for purchasing individual air
conditioners for each room as
well as general use areas, has
been approved by the founda-
tion and the county hospital
board has let a contract for
electric wiring for the project.

Stop condensation on fluid cooling
lines with this new insulation

You can stop condensation on commercial and residential air-conditioning
lines with Armstrong Armaflex®. This new, foamed plastic pipe insulation
completely seals out moisture and air. No separate vapor barrier is needed.
Armaflex remains dry in service, so its low K-factor of 0.28 at 75° F. stays
low for the life of the installation. This insulation also will withstand 200°
F. on hot lines or during the heating cycle on dual-temperature lines.
Armaflex is remarkably flexible, can actually be tied into knots. This
great flexibility can speed installation. Slipped over pipes or copper tub-
ing, Armaflex follows contours readily without any special cutting or fitting.

re

humidities.

If lines are already in operation, Armaflex is simply slit lengthwise, snapped
in place, and quickly sealed with cement.

Armaflex is clean to work with—will not chip, crumble, or rub off. Waste
is negligible. It will not support combustion, is safe to install before sweat
fittings are made. Armaflex comes in 6’ lengths, for all sizes of pipes and

tubing from %4” up to 3%” o.d.

Added by Carrier

cating refrigeration units in
sizes up to 60 hp.

William G. Hillen, applied air
conditioning sales manager for
Carrier’s Unitary Equipment
Div., said the cost reduction
would apply both to installed
price and to operating and
maintenance expense.

CANCELS ‘OPEN DRIVES’

Describing the trend toward
more widespread use of. her-
metic cooling devices, Hillen
pointed out that the primary
feature of a hermetic unit is
that it eliminates “‘open drives”
employing belt and pulley, a
gear box, or other couplings.

“Compressor and motor are
mounted on a single shaft which
is hermetically enclosed sealing”
out dust and dirt,” it was noted.
“The result is that installation
work and resultant cost is re-
duced, space requirements are
cut, and the life of the equip-
ment is greatly lengthened.

“With the Carrier models, in
addition, passage of refrigerant
gas through the motor housing
to cool the motor adds to the
efficiency, thus reducing cost.”

Carrier has been producing
hermetic refrigeration compres-
sors in sizes up to 10 hp. The
line now includes 15, 20, 25, 30,
40, 50, and 60-hp. models.

The hermetic compressors are
said to be “virtually vibration-
less, and almost noiseless.”

PARTS OF UNITS

The new unit will consist of a
motor compressor mounted on
vibration isolators on top of a
condenser. The starting box
mounted on the condenser will
contain starting equipment,
high-low cut-out, oil safety
switch, discharge, suction, and
oil pressure gauges.

When power and water con-
nections are made and the re-
frigerant added the compressor
is ready for use.

On 208/220 volt supply, incre-
ment starters will be furnished
for all sizes, and across-the-line
starters for the 10-hp. size,
Hillen said. On 440/550 volt
supply, across-the-line starters
will be available on all sizes and
increment starters on those of
25 hp. and up, he reported.

Motor compressor assemblies
will be made available with
vibration isolators on rails, he
stated, when the unit is to be
used with other forms of con-
densers.

To Cool Branch Banks

BIRMINGHAM, Ala. — The
Guaranty Savings & Loan As-
sociation here has announced
that it will build three new
branch establishments in the
Birrringham area. All will be
completely air conditioned.

g Purifying Helium

HELPING NAVY BLIMPS to
stay up is the mission of
this portable helium puri- ’
fication trailer, one of six &
built for the U. S. Navy by
the York Corp. subsidiary
of Borg-Warner. After a
certain length of time, the
helium used to keep the
blimp aloft becomes impure
and must be repurified. A
gasoline engine drives the
compressor which draws the
impure helium from the
gas bag, purifies it by

Passing it over drying beds and then further purifies it by condensing the helium
through a York refrigeration system. The helium is then either returned to the gas
bag or put into storage for use at a future date. Compressors, engines, pumps, and
cooling tower are at right in photo above, while drying beds are in large square

structure at left.

New Hetherington

Plant Will Have

Air Conditioning

SHARON HILL, Pa. — Work
got under way recently for a
new one-story, 16,200-sq. ft. air
conditioned building for Hether-
ington, Inc., the manufacturer
announced.

Site of the activity is a 6%4-
acre plot on Hook Rd. in the
suburban Philadelphia communi-
ty of Folcroft, Pa.—one-half
mile from Hetherington’s pres-
ent Sharon Hill plant, it was
added.

According to Joseph Schell-
man, Hetherington president,
the Folcroft plant will provide
urgently needed extra room in
all departments to meet the
growing demands of the electri-
cal, electronic, and aviation in-
dustries. The building will house
administrative, sales, and engi-
neering offices as well as testing
and assembly departments.
Basic parts manufacturing for
Hetherington’s special-purpose
switches and indicator lights
will remain in the Sharon Hill
plant.

Refrigeration System Removes Heat
From Oil Coolant In Buick Factory

According to J. F. Kolder,
works engineering department
at Buick, “any uncontrolled ex-
pansion in the manufacture of
Dynaflow transmission housings
would result in excessive scrap.”

The coolant system operates
by diverting a portion of oil
coolant to a heat exchanger, the
flow being controlled by a dia-
phragm valve. In the heat ex-
changer, using chilled water
from the CenTraVac, the solu-
ble oil is cooled and _ then
dumped into a pump pit where it
is mixed with other coolant oil.
The chilled water is circulated
between the CenTraVac and

Simpler Solenoid Valve Selection May Be Due

Stafford Discusses ASRE Rating, Testing Standard, Considerations In Choosing,
Installing Solenoids, Service Problems, Maximum Operating Pressure

CHICAGO—Current efforts to
develop standards for the rat-
ing and testing of solenoid
valves that should result in
simpler selection for the con-
tractor were described recently
by Willis Stafford, refrigeration
sales, Detroit Controls Corp.

Stafford was a panelist at the
first Product Knowledge Clinic
staged here by Region 6 of the
Air Conditioning and Refrigera-
tion Wholesalers. He also ex-
plained the term “MOPD”
(maximum operating pressure
difference), discussed considera-
tions in selecting and installing
solenoids, and aired some serv-
ice problems.

“The Air-Conditioning & Re-
frigeration Institute is prepar-
ing a standard for the rating of

expansion valves and the Ameri-
can Society of Refrigerating En-
gineers is preparing a standard
for testing solenoid valves,” he
said.

“Also Underwriters’ Labora-
tories have recently reviewed
their requirements for listing
and all manufacturers have
been resubmitting their prod-
ucts for re-examination.”

Stafford’s talk continues:

It is being proposed that line
sizes be standardized for ton-
nage ratings. Also, ratings will
be standardized in accordance
with selected pressure drops
across the valve.

Usually a solenoid valve is
selected to fit the required
liquid line and often times the
pipe size of the solenoid is

more important than the orifice
size. Occasionally it is possible
to choose a smaller size sole-
noid valve if a greater pressure
drop can be tolerated.

If the liquid line is going to
be long, and accumulated pres-
sure drops due to line friction
are large, then the selection of
the solenoid capacity should be
based on the minimum pressure
drop.

If the liquid line is short and
other pressure drops in the line
negligible, it may be possible
to choose a smaller size and
tolerate 4 to 6-Ib. pressure drop
across the solenoid valve with a
consequent greater capacity.

The ARI Standard will recom-
mend the establishing of stand-
ard voltages in solenoid coils.

Air Conditioning & Refrigeration News, February 11, 1957

These are as follows: 115, 208,
230, 460, 115/230 v., all ac.;
6, 12, 24, 32, 64, 115, and 230
d.c.

We would like to emphasize
the availability of 208 v. a.c.
coils. Using the proper coil on
net work systems that have 208
v. is just as important as select-
ing a 208 v. motor for these sys-
tems. That is why this has been
included as one of the standard
voltages.

On d.c. coils it is advisable on
the higher voltages to use a con-
denser to cut down line surge.
These condensers are normally
furnished by the manufacturer,
along with the d.c. coil.

If a solenoid is to be changed
from alternating current to
direct current operation, or vice
versa, be sure to also change
the spacer rings that keep the
coil evenly spaced from the
guide tube assembly. These
rings differ for the two currents
and are not interchangeable.

should be moisture-proof. The
failure of solenoid coils in re-
frigeration applications is due
many times to the infiltration of
moisture and the breakdown of
the insulation.

Most coils are available in
moisture-proof coatings and
should be used. This is particu-
larly important where the sole-
noid valve is to be located in a.
refrigerated space.

On the off cycle, when the
solenoid cools, moisture will
condense on the surfaces and,
if the coil is not moisture-proof,
it will soon be infiltrated by
moisture and a burn-out will
result.

For steam applications, sili-
cone wound coils are available.
This means that much higher
temperatures can be tolerated in
steam coils than formerly. Be
sure when applying a solenoid
valve to a steam system to use
these high temperature pro-
tected coils.

MOP D’

The term “MOPD” is used to
refer to the lifting ability of a
solenoid valve and means maxi-
mum operating pressure differ-
ence. In other words, the num-
ber of pounds per sq. in. be-
tween the inlet pressure and the
outlet pressure that the valve
will open against.

Underwriters’ requirements
have established that the MOPD
be given at 85% of the normal-
ly rated voltage supplied to the
coil. All nameplates on solenoid
valves will indicate the MOPD
which means that this is the
pressure difference that the
valve will operate at 85% of
the nameplate voltage.

MOPD is not to be confused
with safe working pressure. The
safe working pressure of a sole-
noid valve means, as the state-
ment implies, the total line
pressure to which the solenoid
valve can be safely subjected.

INSTALLATION

There are several things to
consider when installing a sole-
noid valve, after the proper
selection has been made. Many
solenoid valves now come in
sweat connections and will be
subjected to heat when they are
installed. Always remove the
coils from these valves before
installing them so they will not
be damaged by the heat from
the torch.

Also, many solenoids now
contain synthetic materials for
seats and some of these may
also be damaged by the solder-
ing torch. Usually, such sole-
noids are so tagged and the
parts containing the synthetic

Solenoid Valve Selection- -

material must be removed be-
fore the torch is applied.

Be sure that the voltage of
the line to which the solenoid
will be connected matches the
coil voltage. Many times, this
precaution is not taken and a
burned out coil is the result.

All possible precaution should
be taken to keep foreign matter
out of the solenoid valve during
installation. Many solenoids
have failed because of dirt,
shavings of metal, or pieces of
solder lodging inside the valve.

It is a good practice to install
a strainer ahead of all solenoid
valves to protect them from
foreign matter. Many solenoids
now have built-in strainers,
which provides this protection.

SERVICE
Probably the most frequent

solenoid failure occurs because ”

of the varying voltages to which
the coil is subjected. Unfortu-
nately, these varying voltages
are very often difficult to deter-
mine. Many times, when the
serviceman arrives on the job,
the low voltage that caused the
solenoid valve to fail no longer
exists and he can find no ap-
parent reason for the failure.

It is well to remember that a
solenoid valve must have full
voltage at the instant of open-
ing. If, for example, a solenoid
valve attempts to open at a
period when the voltage is low
and then the voltage immedi-
ately increases but without in-
terruption of current, the sole-
noid plunger still will not lift off
the seat, until the coil has been
deenergized and another open-
ing attempt has been made.

This causes confusion because
the user of the equipment very
often will hear a solenoid valve
humming after it has attempted
to open on low voltage and thus
will turn off the current to the
solenoid valve.

When the serviceman appears
and turns on the current again
the voltage may be normal and
the solenoid valve will work
properly—if the coil has not
been damaged. One answer to
this problem is a recording volt
meter which will catch these
variations in voltage.

Many solenoid valves now
contain internal strainers. When
strainers become blocked the
solenoid stops flowing. Some of
these strainers are at the inlet
connection and form part of the
flare face on SAE connection
valves. These are easily accessi-
ble by removing the inlet line

connection and removing the
strainer for cleaning.

Other solenoids have _ the
strainer inside the body itself.
When this type of strainer is
encountered it is necessary to
remove the coil and guide tube,
then lift out the strainer.

Larger solenoid valves usually
have a manual opening stem at
the bottom of the body. This
consists of a packed valve stem,
which can be turned into the
body to manually lift the piston
from the seat in the case of
power failure or coil burn-out.

Quiet often, this valve stem
has been mistaken for an adjust-
ment and has been turned part
of the way in, thus preventing
the solenoid from closing pro-
perly. All manual lift stems
should be left in the full out or
open position.

Finally, never operate the

solenoid with the coil cover re-
moved. The steel coil cover
forms a part of the magnetic
circuit. A solenoid valve is an
electromagnet and, when ener-
gized, an attempt is made to re-
duce the air gap through which
the magnetic lines must pass.

The steel housing, surround-
ing the coil, is part of the mag-
netic circuit. If this cover is not
in place the air gap is increased
and the resistance to flow of
magnetic lines increases, caus-
ing a higher than normal watt-
age draw through the coil.

Solenoid valves operated with-
out coil covers for any length of
time will cause coil burnouts
quickly.

1,888-Mile Service Call
—Motor Needs Oil

LA CROSSE, Wis.—The Trane
Co., manufacturer of air condi-
tioning and heating equipment,
has always taken pride in its
far-flung service organization—
and its reputation to service a
job no matter what.

But when Jim Mack submitted
a report covering a 1,888-mile
service call, there were some
raised eyebrows — especially
since the job in question was

only 180 miles away from
Mack’s Louisville, Ky., head-
quarters.

This is what happened.

Mack flew to Evansville, Ind.
—a 36-minute hop—was met by
a contractor and driven 55 miles
to the job site at Petersburg,
Ind.

On the return flight the pilot
was attempting to land on a new
runway at Louisville only to dis-

1 cover it was under construction.

The pilot pulled up for a second
try as fog descended on the
airport.

Unable to land, the plane flew
non-stop to La Guardia field in
New York. Mack flew back the
next morning. Total mileage—
1,888.

“And all for a motor that
needed oiling,’’ was Mack’s com-
ment.

GENERAL ELECTRIC’S PORTABLE LEAK DETECTOR HELPS CONTRACTORS...

Make Jobs Leak-Tight; Cut Service Costs

Service repair reductions of 85% have
recently been reported by a G-E Leak
Detector user in Michigan who installs
air conditioning equipment. Similar
savings of time and labor can be yours
when you use General Electric’s Leak
Detector to assure your customers a
leak-tight initial installation of recipro-
cating, rotary or centrifugal compres-
sors; household, commercial or indus-
trial refrigeration systems. And you can
handle service calls faster and more
effectively during the busy summer
months by using this simple instrument
to “sniff out’ troublesome leaks in in-
stallations which you service.

Existing light has no effect on the
efficiency of your inspection procedure
with the General Electric Type H-1
Leak Detector and even unskilled oper-
ators can find leaks so small that in
100 years, only one ounce of Freon*
gas would escape.

A true leak signal is assured because
the Type H-1 detector automatically
offsets slow changes in background con-
centrations of halogen gases. Only a
true leak of kalogen gas causes a
response. Leaks are indicated by an
instrument dial as well as by a variable-
pitch loudspeaker or earphones.

Readily portable, the unit weighs only
2414 pounds. It is well suited to use in
your shop as well as for service testing
in the field wherever alternating current
is available.

Apparatus Sales Office or write for

Inside Dope

By GEORGE
F. TAUBENECK

(Continued from Page 1, Col. 1)
ably won’t be long before we
have the clue to cancer and can
checkmate it with pills. Same
prediction can be made for heart
diseases of all kinds. It’s just a
matter of time.

Furthermore, our doctor
shortage probably can be allevi-
ated by electronic “brains”
which will diagnose and pre-
scribe!

And with pills to relieve every-
thing from worrying about what
competitors are doing to amino
acid compounds which will make
a man of 60 feel like 20 again,
what a world we'll have!

Better and Cheaper Stuff

To proceed from the animate
to the inanimate, strides in the

direction of new man-made ma-
terials border on the fabulous.
Just a few weeks ago Shell Oil
announced that irradiation of
petroleum is giving birth to a
whole new family of plastics,
with properties which make pre-
vious plastics seem anemic.
These new compounds run the
gamut from replacing structural
steel for skyscrapers to mate-
rials which will make space
travel feasible.

It is predicted these new syn-
thetics will be so cheap and easy
to fabricate that the clothes
washer will become obsolete.
We'll just throw away our shirts
and sox after one wearing.

In that connection, supersonic
sound-wave cleansing not only
will keep a house dust-free, but
automatically will flick the mud
off children’s shoes before the
kids burst into the house from
outside!

New low-cost materials will
bring prices down, too, and
plenty. No longer will the steel

workers’ union be able to set
off a whole new round of infla-
tion every year, because no
longer will steel be the key to
our entire economy.

Furthermore, a-spawning fam-
ilies of synthetics will simplify
manufacturing processes. In-
stead of the complicated assem-
bly of an automobile or refriger-
ator from hundreds of finely-
machined parts, major sections
will be cast whole, in huge gobs.

Miners may become a vanish-
ing race. More and more mate-
rials will be made (synthesized
from chemicals).

Free as the Sun

As everybody figures, atomic
energy eventually will cut power
costs enormously. Roger Kyes
of General Motors even fore-
casts that individual homes will
have their own atomic power
plants. This might seem to be
bad news for the public utilities,
at first glance—but they’ll have

Air Conditioning & Refrigeration News, February 11, 1957

other roles to play, and other
tools with which to play. Among
those “other tools’—refriger-
ated transmission lines which
may revolutionize the electric
power industry by slashing costs
astoundingly.

Also, it now appears that the
big steam generating plants
will become obsolete, likewise
waterpower. Thus the political
debates between government
dam enthusiasts and private
power advocates may seem silly
in retrospect. Likewise worry
over Arabian oil and the Suez
Canal.

Three new sources of cheap
energy visible over the horizon
include these obsoleters:

1. Direct conversion of atomic
energy into electricity—without
intervening steam.

2. The fuel cell—combinations
of chemicals and gases to pro-
duce enormous quantities of
electricity from a tiny unit. It
would require several books to

go into this development, but
some think it will put atomic
energy out of business before it
gets well started!

3. Solar energy. Here is the
real jackpot. “Free as the air”
may be replaced as an expres-
sion by “free as the sun.” When
the sun’s rays are harnessed
effectively, as they will be,
power charges may be next to
nothing.

In the meantime, radiant heat
will keep football watchers
cozy in outdoor stadiums, and
allow us to sleep without blan-
kets. Also, automatic controls
will heat and start your car on
a cold winter morning, park it
automatically, even drive it!
Portable two-way television will
supplant baby sitters. And
meals will be cooked by tele-
phone.

Instantaneous communication
—by telephone or wristwatch
two-way radio and television—
anywhere in the world. These

expectations no longer are news.

They’re operating daily in the
comic strips. And our sons take
their eventuality for granted.
So do electronics engineers.
Likewise, almost instantane-
ous transportation won’t be
surprising. That “flying carpet”
of the Arabian Nights tales
almost is with us already. We'll
probably call it a Monocopter.

Personal transportation at
25,000 miles an hour on this
globe is being crystal-balled.
Space travel at the speed of
light actually has been postu-
lated. Einstein had a formula
for it, and a young California
physicist was quoted recently
that, given a “crash program,”
he could make it a practicality.

The latest table-talk among
the rocket and missile men has
to do with the physics (and
metaphysics) of photon propul-
sion: thrust for a space vehicle
derived by shooting incredibly
concentrated beams of light
(photons) from its tail. Result
—speeds surpassing that of
light. Our authority for this
statement? The Martin Aircraft
Co. of Baltimore.

Instead of Killing Each
Other, We'll Kill Time

Already there is reason to
hope that the H-bomb, with its
power to obliterate an entire
nation, has forestalled a World
War III.

Thanks to automation—plus
the coming new power sources
and materials mentioned previ-
ously—we should enjoy leisure
to an undreamed of degree.

Our fathers worked six days a
week. We work five now. For
our sons the four-day weekend
seems a cinch, thanks to auto-
mation.

Those few examples of auto-
mation in factories ‘“Dope’’ has
seen already indicate that elec-

tronic brains (coupled to ma-
chines and cheap power) can do
most of the world’s work.

Their further development
will give us more time not only
to have fun—but to perfect
human relations—which have
lagged far behind scientific ad-

for peace abound.

How To Guide Your
Grandson

At this moment our Future

CHICAGO—A discussion of
space heating will be a feature
of the American Power Confer-
ence to be held March 27-29 at
the Sherman hotel here.

Sponsored by the Illinois In-
stitute of Technology in coop-
eration with 14 universities and
nine local and national engineer-
ing societies, the conference is
“to provide a forum for ex-
change of information in power
generation, transmission, dis-
tribution, and utilization.”

Wednesday, March 27 from 2
to 5 p.m. is the time set for the
space heating, discussions under

John I. Yellott,, executive direc-
tor, Association for Applied
Solar Energy, chairman. Co-
chairman will be Gil Freyder,
engineer for the Common-
wealth Edison Co. of Chicago.
“The Place of the Heat Pump
and Solar Energy in Space Con-
ditioning,” constitutes phase
one of the talks. R. C. Jordan,
chairman, department of me-
chanical engineering, Universi-
ty of Minnesota, will speak.
Phase two is “Electric Heat-
ing in the Tennessee Valley—A
Pattern for the Future,” dis-
cussed by W. R. New, super-

visor of Special Studies Sec-
tion, Div. of Power Utilization,
Tennessee Valley Authority.

Third part of the program
will be “Air Conditioning with
the Compound Heat Pump,”
covered by Sidney Miner, indus-
trial sales manager, central dis-
trict, York Corp.

The three papers will be
among approximately 85 to be
presented in the course of 23
sessions of the three-day meet-
ing.

Cooperating technical socie-
ties include the American So-
ciety of Heating & Air-Condi-
tioning Engineers.

Inquiries concerning’ the
meeting should be addressed to
E. R. Whitehead, ITT, 330 Fed-
eral St., Chicago 16.

New Firm To Create, Maintain
Cooling, Heating Distribution

GRAND RAPIDS, Mich. —
Earl Palmer, A. L. Kawsky, and
K. H. Luse have formed the
sales, engineering, and advertis-
ing firm, Lord & Palmer, Inc.,
with headquarters here.

Lord & Palmer will specialize
in creating and maintaining air
conditioning and heating distri-
bution on a national basis, said
Palmer, who with his associates,
was formerly with the air con-
ditioning division of Gibson Re-
frigerator Co. Regional person-
nel will be located in all major
market centers.

Palmer believes that the new
organization is unique.

would seem to belong to the
scientists. If you have a boy
of high school or college age, by
all means encourage him to
latch onto some branch of
physics, chemistry, electronics,
engineering.

To the lads and lassies of
junior high school age who are
going to their first parties, how-
ever, it might be wise to stress
social activities. The future
belongs to those who can per-
suade, entertain, and get along
well with their fellowmen and
women.

That New Age of Leisure is|
the key and clue to their oppor- |
tunities. |

Thanks to rapid acceleration
of science: doctors, lawyers, |
engineers, and soldiers may be |
less frantically needed in the)
1970’s than now.

Truly great careers will be
open to young folk who can
communicate pleasingly. Teach-
ers, preachers, entertainers,
writers, speakers, diplomats—
yes, and politicians—will be in
highest demand during the com-
ing:

Commercial Distributor’s Customer Services Are Varied

PORTLAND, Ore.—A_ dis-
tributor of commercial refriger-
ation equipment in_ today’s
scheme of things must be more
than a firm that takes orders
for food store equipment and
gets it installed properly. In
fact, to do any kind of a volume-
building job it must literally be
able to plan a whole new store
operation for the food merchant.

A prime example of this
“modern” type of distributor
operation is the Portland Fix- ——
ture Co. here. Confining its ment per week from the McCray
operations strictly to the com- Refrigerator Co. plant in the Northwest
mercial refrigeration and store past year. where his early business experi-

business, and has averaged veteran in the store fixture helpful in his present occupa- activity which might be termed operations. First and foremost

better than a carload of equip- business, and Louis Zimel, a tion. principal factors in the Portland is the fact that the distributor
eomemnacs has its own store planning de-

partment.

This department has more
functions than merely laying
out a floor plan and indicating
where the fixtures should be
placed. In actuality, the store
planning department is capable
and qualified to start a retail
food store from the selection of
the plot of ground on which it
will be located, to the comple-
tion of a supermarket type of
store.

Cooperates with
Wholesale Grocers

A second principal activity
which Portland Fixture has
found extremely important is
that of working cooperatively
with wholesale grocers. The
wholesale grocer has also be-
come something much more
than an order-taker. A recent
survey of the activities of this
| group showed that nearly all of
them are active to some degree
in assisting food merchants with
new stores, and that 66% of
them have store engineering
departments or personnel.

So, Portland Fixture can de-
velop a systematic approach to
selling equipment for a new
retail food store, with an almost
certain guarantee of customer
satisfaction, in an approach that
goes something like this:

This is how to get

BETTER RESULTS
FROM WATER COOLING TOWERS

Example of Approach

1. A contact with one of the
many wholesale grocery firms
with whom the distributor co-
operates for mutual benefits, to
create the interest of a retail
food store customer in a loca-
tion or situation which the dis-
tributor and wholesale grocer
have investigated and approved.

2. Through experience they

14

On water-cooled refrigeration and air condi-
tioning jobs, the cooling water temperature
must be right to maintain correct refrigerant
head pressure for highest efficiency.

But, when the load varies or outside temper-
ature and humidity are low, the cooling water
temperature drops. Then the supply of cold
water to the condenser may greatly exceed re-
quirements which lowers head pressure and
compressor capacity.

A simple solution to this problem is to install
a Penn Series 247 reverse-acting water valve in

a by-pass around the condenser as shown in
above diagram. Then, if head pressure drops,
the valve opens to allow more water to flow
through by-pass. As head pressure rises, the
valve modulates to restrict flow in by-pass and
supply more cooling water to condenser.

Result? Correct head pressure at all times
for more efficient operation of commercial re-
frigeration and air conditioning compressors.
Use this method, it will save money . . . get the
simple installation data from your wholesaler
or write the Penn factory.

are in a position to tell the
prospective new store operator
how large a store can be oper-
ated profitably in a certain loca-
tion, going through gross vol-
ume figures to the ultimate new
profit picture.

3. Then a tentative store plan
is laid out from which the pros-
pect can analyze the operations
and fit it to meet his personal
requirements. (This gives an
individual and personal touch to
each store.)

4. At this point a lot layout
has been made and the location
of the building and the parking
space on the lot has been estab-
lished.

5. When the store planning

Distributor’s Customer Services--

(Continued from preceding page)

has been completed and accepted
by the customer, the order has
been taken. Then, with the
guidance of the distributor, an
architect is consulted about the
building. The contracting for
the actual construction of the
building is usually handled on a
bid basis.

6. Once the building has been
completed, the plumbing, elec-
trical, and refrigeration contrac-
tors are called in to complete
the installation of equipment.
Each are usually furnished with
a layout of how the equipment
is to be installed.

7. During the final stage of
the program, Portland Fixture
Co. keeps as much control of the
job as possible, and coordinates
the work of everyone concerned
to make certain that the final
completion date will be met.

Most of the financing for the
store equipment is done through
local banks, but in some in-
stances Portland Fixture Co.
will carry the paper.

Refrigeration Service
Work Has Fixed Rate

All refrigeration service work
is contracted for at a fixed rate,
and, where feasible, one service
and _ installation organization
does all of the installation work.
The volume of business being
done by the distributor has kept
one such firm working on Mc-
Cray installations only.

Portland Fixture Co.’s own
place of business is a three-
story building with a complete
basement. In this building is a
showroom which measures ap-
proximately 60 by 100 ft. The
distributor aims at keeping at
least 20 pieces of equipment for
showroom purposes, and at least
30 more pieces of McCray com-
mercial refrigerator models in
stock at all times. The purpose
of the stock is to be in position
to install a complete market if
necessary.

Seven salesmen work out of
the Portland office. In addition,
the distributor services the fol-
lowing five dealers: Olson &
Quick Co., Eugene; Smith’s Re-
frigeration, Pendleton; B. E.
Bowman, Portland; Newport
Refrigeration, Newport; and
Columbia Refrigeration Service,
The Dalles.

The Portland Fixture Co.
offers its dealers all of its exten-
sive store planning and other
facilities, for use in the dealers’
own sales operations.

Thinks Success Due
To Salesman Training

The management of the com-
pany believes that much of its
success is attributable to the

©

thoroughness with which its
salesmen are trained. Applicants
are carefully screened and pref-
erance has often been given to
those who have had some con-
nection with the food retailing

mentals.

When this “basic training”’ is
completed, one of the directors
will take the new salesman and
familiarize him thoroughly with
a new market about to be in-
stalled. Then, under the careful
supervision of the director, the
new salesman is made responsi-

‘ ble for the entire installation—

location of cases, gondolas, and
shelving; layout of such special
spots as a pre-packaging room;
installation of plumbing, elec-
tricity, and other utilities; and
the 101 details that go into a

completed job. Thus the new —

salesman “goes through with”
all the details of completing a
new market job.

This training period may con-
tinue for a year or more. During
this time leads on smaller in-
stallations are turned over to
the salesman to develop, and he

major new store or renovation
project.

Emphasis is placed on the
working arrangements that
Portland Fixture Co. has de-
veloped with wholesale fixtures
houses. These connections are
of vital importance because they

when they aren’t invo'ved in a often help to get the distribu-

tor’s salesmen “in on the deal”
weeks ahead of competition, but
also because the grocer will

' often listen to and accept a

grocery salesman’s recommenda-
tions on remodeling and equip-
ment plans.

Another factor in the con-
tinued growth of Portland Fix-
ture Co. comes from the dis-

} tributor’s not only keeping up

with innovations in food store
design and merchandising
trends, but also in providing
some of its own innovations. A
couple of recent jobs illustrate
this point.

Young’s Food Mart, Inc. in
Portland was increased in size
from an original store size of
3,000 sq. ft. selling area to
10,000 sq. ft., with a total area
of 13,000 sq. ft. Additional
space for a drug and variety
store, cafeteria, and bakery
added up to an over-all shopping
center area of 21,000 sq. ft.
Volume of the Food Mart is in
the $30,000 a week area.

Renovation Features

Here are some of the special
features of the renovation:

A mezzanine for office space,
employes’ lunch room and wait-
ing room, with enough floor
space for special store promo-
tion attractions such as orches-
tras.

Drug and variety store sepa-
rated from the food retailing
area by a common lobby which
provides entrances for east and
west sides of the building and
also provides space for bakery,
cafeteria, and other merchandis-
ing and special displays.

A package pick-up station,
and 200-car parking lot—which
can be expanded to accommo-
date 500 cars.

High Velocity Air Distribution

Some Methods of Simplifying Design, Installation
Problems Suggested by 4 Engineers

CHICAGO—A review and a
brief peek into the future of
high velocity air distribution
systems was presented at the
January meeting of the Illinois
Chapter of the American Society
of Heating & Air-Conditioning
Engineers.

A total of 202 members and
guests were present.

A panel of four engineers told
about their experiences with
various types of systems, the
components used, and what has
been learned about the charac-
teristics of different systems
and equipment.

Some recommendations were
made that should simplify the
problems encountered in design-
ing and installing systems of
this type in the future.

Sam Sachs, chief mechanical ,
engineer, Skidmore, Owings, &)
Merrill, told why high velocity
systems are growing in number
each year. Sachs pointed to the
high costs involved in the erec-
tion of buildings and the at-
tempts being made to keep these
costs down. The result is often
a reduction in the space allo-
cated to the essential equip-
ment.

He also mentioned the con-
tinued rapid growth in the sum-
mer air conditioning of exist-
ing buildings and the problems
involved in locating standard
size ductwork for low velocity

NEMA TV Spots Push

Electric Home Heat

NEW YORK CITY—An effec-
tive and entertaining series of
six 1-minute television spots
based on the full-color sound
slide film, “Heat Your Home
Electrically,” produced by The
Electric House Heating Equip-
ment Section of the National
Electrical Manufacturers Asso-
ciation, is now available, accord-
ing to Melvin Wessel, section
chairman and sales manager of
Cavalier Corp.

The television package utilizes
much of the artwork used in the
widely distributed film. It is de-
signed to capture and hold an
audience’s attention while facts
concerned with electric heat’s
advantages are presented “in
amusing and convincing style.”

These sound-on-film spots are
available in either black and
white or color. Standard copy
carries through the “Live Better
Electrically” theme. Tailored
packages offer sponsors an op-
portunity to insert company
names at the beginning or near
the end of the presentations.

The TV spot packages are
endorsed by the NEMA Electric
House Heating Section and may
be obtained from Continental
Products Corp., 539 Vine St.,
Chattanooga, Tenn.

New AMCA Member

DETROIT—The G. C. Breidert
Co., San Fernando, Calif., has
been elected to membership in
the Air Moving & Conditioning
Association (AMCA), an-
nounces G. C. Breidert, presi-
dent.

The company manufactures
power roof ventilators for venti-
lation of commercial, industrial,

air distribution. Another point
brought out was the growing
trend toward the use of perim-
eter heating for new multi-
story office buildings.

Bill Batchelor, chief engineer,
Tuttle & Bailey Co., outlined the
development, application, and in-
stallation of dual duct outlet
boxes. The basis for the solu-
tion of problems involving pres-
sure reducing boxes was a maxi-
mum noise level of 40 decibels.

He pointed out that five es-
sential requirements had to be
met by the outlet box. These
are:

(1) A damper that will de-
velop a pressure drop as air is
supplied from the high pressure
duct system; (2) a mechanism

that will provide temperature

Uy.
bi

i

and volume control of entering
low pressure air; (3) the box
should be acoustically treated
for noise control; (4) air vanes
that will insure a free mixture
of hot and cold air streams; and
(5) an adjustment for the air
outlet.

William Tracy, manager, sales
department, Sturtevant Div.,
Westinghouse Electric Corp.,
described the development of
blowers for high velocity air
distribution systems.

He said that the air foil
curved bladed fan is gaining
rapidly in popularity because
tests show that an efficiency of
92% is not unusual. This is an
increase of 12 to 14% over
other types of blowers used in
similar applications, he claimed.

- News in the Heating Field ~

Another advantage of the air
foil blade fan pointed out by
Tracy was the low noise level
at which it operates.

Norman J. Janisse, field engi-
neer, Johnson Service Co., dis-
cussed the controls needed for
high velocity air systems. He
recommended that mixing box
dampers be designed so that
air from either the hot duct or
the cold duct would always be
entering the mixing chamber.

Also recommended was the
control of the hot duct air tem-
perature “as this is the easiest
way to control the humidity.”

He pointed out that the tem-
perature of the air in the cold
duct is more difficult to control
because the dewpoint of the air
at the equipment must be
reached to control the humidity.

He also expressed the opinion
that new experiments now being
conducted in many private lab-
oratories would probably change
the design of many mixing boxes
being used today.

Tremendous Growth Possibilities
Of Commercial Refrigeration
Based on ‘Leisure’ Foods

(Concluded from Page 1)

cube dispensers) commercial refrigeration
dealers and manufacturers haven’t had a
great deal to get excited about for a long
time. That cube machine has been a real
big money-maker for a few manufacturers
and quite a few dealers. But it is an excep-
tion.

Within recent memory a typical com-
mercial refrigeration dealer enjoyed good
business volume on the entire variety of
specialized refrigeration products. One by
one, several have slipped away from him in
recent years. Items:

(1) Ice cream cabinets are sold directly
by manufacturers to dairy firms, which
“rent” them (dollar a year, say) to ice
cream purveyors. .

(2) Water coolers are sold “directly,”
also—to commercial and industrial mass
purchasers.

(3) Frozen foods (orange juice is a
prime example) storage cases are bought
by national distributors; then installed
without charge in food stores and serviced
by those national brand purveyors.

(4) Chain stores buy commercial cases
in quantities straight from manufacturers
—again by-passing the local dealer.

We predict, however that within the
next five years, and for a long time there-
after, commercial refrigeration will become
not only a tremendous Growth Industry, but
a bonanza for commercial refrigeration
dealers.

Why? Because “the new leisure”
(shorter working days and weeks for men
lead their wives into seeking shorter work-
periods, too) is zalooming the market for
frozen foods of every conceivable descrip-
tion.

Ready-cooked frozen foods are the phe-
nomenon of the food trade business. And
soon this trend (which calls for multiplica-
tion of frozen foods storage space in grocery
stores, clubs, hotels, etc.) will make previous
sales volume figures for commercial refrig-
eration look like small potatoes.

In 1955 Americans ate up frozen food at
the rate of 45 lbs. per capita, compared
with 41 Ibs. in 1954, and with 17 Ibs. in 1949.
Last year the industry packed a mountainous
4,410,000 Ibs. of frozen foods of all types.

18

That was almost double the previous record
pack.

Home freezers sold during the last nine
years surpassed eight million, and they con-
tinue to sell at a rate of more than a million
a year. Moreover, new and bigger household
refrigerators, most of which now are equip-
ped with larger freezer chests, possibly
double the amount of home frozen food
storage space added annually.

Grandma canned, mother opened cans,
daughter thaws. Right there is the “hooker”
in the commercial refrigeration business.

From a limited line of a few fruits and
vegetables a few years ago, the roster of
frozen foods has expanded to include more
than 300 raw foods and at least 400 heat-
and-serve complete meals.

You name the variety of pre-cooked
frozen dinner you want. Your wife can buy

it already prepared (frozen, of course). It =

takes only moments to serve it, and then
she has time to join you and the family in
“new leisure” activities. Mamas and grand-
mas of all ages and in all stations in life
(domestic servants are vanishing) go for
this stuff in a huge way.

Luxury frozen foods presently include
cornish hens, smoked pheasants and ducks,
stuffed barbecued chicken, veal and beef;
plus fresh trout, chicken a la king, hors-
d’oeuvres, egg rolls, exotic soups, pizza pies,
macaroni, ravioli, blintzes, sauced Chinese
foods, de-veined shrimp,

deviled crab, . After reading means of Intro-

refrigeration manufacturers and dealers. To accomodate
the acceptance (let’s say: “demand’”’) from housewives who
need to conserve time, and who wish to serve more luxurious
meals, food retailers will have to augment their low tempera-
ture refrigeration equipment tremendously and quickly.

Recently John M. Toolin, an A.&P. executive retired
after 31 years of studying and analyzing food retailing
trends. Here’s what he predicts for the future.

“Any grocery item you can think of will be available in

frozen packets—neat, heat, and eat. Food stores of the
future will consist entirely of self-serve frozen foods cases.”

What a wonderful outlook for commercial refrigeration

Air Conditioning ¢ Refrigeration News, February 11, 1957

(Concluded from preceding page)
pay and can’t afford what other
people can. I find in my part of
the country top pay after a good
summer about equals that of the

average factory worker. I’ve
found a lot of men working
alone, that say they don’t want
another man because of the
bookkeeping and extra work of
keeping one busy. They take
the jobs that pay the most
money and forget the ones they
don’t get time for. Unions have
caused me trouble too. Some-
day where I live refrigeration
men should be in big demand.
I hope to make a career of the
work but I need a job where I
can earn a living. I thought the
writer of the article in your
paper should know a few of the

ter to RSES requesting infor-
mation along these lines. The
case in point, although not men-
tioned in that letter was this.
I had working for me at the
time, a young man, 21 years
old, who had three years in the
Air Force with one year left
to do. Naturally, being in the
Air Force myself, I tried to talk
him into staying but he said he
wanted no part of it. He was
ready to try it on the outside.
The next best thing I could do
was to persuade him to stay in
the profession. The man had
worked for me about 18 months
and I believe would eventually
shape into a number 1 service-
man. The big questions in his
mind were, where would he start
on the outside, what could he

expect as far as jobs go, how
long should he expect to serve
as an apprentice before he
would attain journeyman sta-
tus? All of these questions may
seem trivial to the old timers
in the trade, but they carry a
lot of weight with the young
ones, the ones you pointed out
in your article, we are after. I
will have to agree with you that
there is no shortcut to success,
but it sure seems that if a per-
son has some direct questions
related to a career he should be
able to receive some direct
answers. Good or bad would de-
pend on the person’s interpreta-
tion of them. To illustrate, I
offer the following. A 15-year-
old boy knows that he can buy
a train ticket in Los Angeles
and be in New York City 3 days
later by train. It took a billion
dollar organization to make this
possible but the point is, every-
one understands it sufficiently
that they make use of it. Isn’t

there some way we can get the
word out to these people who
are seeking the answers. Possi-
bly a column devoted to this
subject once a month could be
a starting point. In the column
could be listed what the big-
gest shortages are manpower-
wise and a possible listing of
recognized schools.

I am sorry to say that I
couldn’t answer this lads ques-
tions. Being in the service for
16 years has put me out of
touch with policy and procedure
out there. I hope I haven't
bored you with this and further
hope that it may be the basis for
one of your editorials. It may
be that my being out of the
states for the last four years
has made this situation look
like a mountain in my eyes. If
so, I stand to be corrected. I
will be able to see for myself
next month as I return to the
states then.

UNIFLOW SWITCHES TO RUBATEX TUBING FOR
SWEAT-PROOF INSULATION AT LESS COST

Cold lines in six Uniflow water cooler fountain models

closed cellular rubber tubing insulation.

“We find Rubatex particularly

applicable to our uses mainly be-
cause it doesn’t absorb water and
at the same time provides the in-
sulation necessary at the points
where it’s used. We also believe
Rubatex will last longer. Lower
initial cost and fast deliveries were
additional influencing factors in

Win an eleven-day Caribbean vacation cruise

(We’ve chartered the entire ship — funnels, anchor

and crew to make sure you have an unforgettable holiday.)

And don’t miss the boat on becoming the mosf successful

Jewel of the Golden Bahamas,” tour picturesque
Jamaica, see the exotic sights of colorful Havana,

ELEVEN GLorious Tropic Ho.ipays!

All Carrier dealers are in on this contest. You’re
eligible, no matter what your product line—Room
Air Conditioners, Residential Air Conditioners,

Here are ten good reasons why the Carrier
franchise is the most valued in the industry.

1. A Carrier dealer gets engineering help from his dis-
tributor on difficult jobs. His distributor knows the air
conditioning business and he understands dealer problems.

2.A Carrier dealer receives continuous training in the
most modern techniques for air conditioning engineering,
selling, installing and servicing.

Icemakers. |

Every single expense aboard ship will be paid
by Carrier. You won’t be able to spend a cent.
Ashore Carrier will pick up the tab, too. The only
money you'll spend will be for family gifts.

The Tropic Holiday Contest lasts all year, ends
in November. No panicky deadlines, no pressure
to produce overnight. Any dealer can win in his
own good time. No pierda el barco!

3.A Carrier dealer can obtain expert management con-
sultation on any phase of his business operation. As-
sistance in accounting, financing, inventory control,
personnel compensation, etc.

4. A Carrier dealer doesn’t have to tie up his own capital
in inventory. Under a special Douglas Guardian Ware-
house Plan he enjoys the benefit of having the equipment
he needs on hand and yet he pays nothing, not even inter-
est, until the equipment is sold.

5. A Carrier dealer is protected against price reductions

on unsold inventory at all times. If he buys his equipment
before the selling season begins this price-protection can
last for up to eleven months.

6. A Carrier dealer enjoys the most liberal product warran-
ties in the business. These high allowances assure cus-
tomers’ satisfaction without affecting dealer profits.

7.A Carrier dealer gets sales support from the Carrier
National Buyer Organization. This team sells national
firms who require air conditioning installations in the
dealer’s town, turns the order over to the dealer.

support. Both nationally in magazines and in television,
and locally in newspapers, radio, television; in fact, wher-
ever he wants advertising support.

9. A Carrier dealer enjoys unequaled prestige—his prod-
ucts are known and respected. The Carrier dealer is Mr.

from the potential market for air conditioning, his future
growth and success are unlimited.

What’s New

Motorless, Pumpless Carbonator Introduced

‘a

KEY NO. G-220————

NEWARK, N. J.—A new motor-
less, pumpless carbonator in a
transparent housing was recently
introduced by Yan-Nell Industries.

Standard model has a capacity
of 30 g.p.h. operating at water
pressure of 20 lbs. Larger capaci-
ties are possible with higher water

pressures, the company pointed
out, or the height of the unit can
be increased. If necessary, the
carbonator will operate on gravity-
fed water.

Called the ‘Jet. Carbonator,” the
unit has only one moving part.
With its transparent housing, it
can be displayed in full view. Body
of the unit consists of two cylin-
drical chambers. Water is carbon-
ated in the charging chamber
under constant pressure from a
60-lb. gas line.

When charging chamber falls to
refill level, an electrical relay oper-
ates a valve to permit pressure
from an intermittent carbonating
gas line, connected to the reservoir
chamber, to act in place of a pump.

Impulse from the liquid level
control relay shuts off the pump-
ing gas line and gas in the water
reservoir is allowed to vent, the
firm said. The reservoir is then
replenished from the main line,
and a float valve makes the sole
move in the cycle to complete the
operation.

ported.

It will carry a suggested list
price of $329.95, the manufacturer
was quoted.

Other Philco upright freezers
include model 2072 which is a
20-cu. ft. freezer and model 1472, a
14.6-cu. ft. freezer. Three chest-
type freezers, model 1872, 18.6-cu.
ft. capacity, model 1375, 13-cu. ft.
capacity, and model 872, 8.4-cu. ft.
capacity, are also included in the
1957 freezer line, the company
announced.

Self-Closing Device

Shuts Barr Doors

KEY NO. G-222

OAKLAND, Calif.— Barr Mfg.
Co. here recently developed a self-
closing device for its hinged
refrigerator doors.

Termed “Torkk,” the arrange-
ment is ‘a spring steel rod which
acts as a torsion against the door
in open position. As the door is
released the tension on the torque
rod carries the door to a closed
position, the company stated.

Torque rod is welded to hexa-
gons on each end which are used
to adjust speed of closing. The
device is entirely concealed inside
the door, has no wearing parts,
the firm explained.

Logo Develops
Roll-On Finish

KEY NO. G-223————

CHICAGO — Recently developed
by Logo, Inc. was a screening and
roll-on finish designated RV-300.

The material may be applied to
a wide variety of surfaces in the
plastic line, it is said to have e-
cellent adhesion to all thermo-
plastics except the acetates and
polyethylenes.

Warm Air Furnace
Control Announced

KEY NO. G-224————

LONG BEACH, Calif.—Robert-
shaw-Fulton Controls Co., Grayson
Controls Div., here recently an-
nounced a new automatic gas
heating control for use with warm
air furnaces.

Known as “Unitrol 400-E,’”’ the
new furnace control combines gas
cock, thermostatic valve, and
automatic pilot in one compact
unit, the company said. Thermo-
static valve operates on heat
motor principle on 24 v. a.c.

Unitrol 400-E has snap-action
gas valve for positive and com-
pletely silent performance, it was
pointed out. The automatic pilot
is a 100% shut-off type.

Other advantages claimed for
the unit include ease of installa-
tion with only two pipe fittings
necessary.

Haveg Has Light,
Heavy-Duty Glass Tanks

KEY NO. G-225———

WILMINGTON, Del.—Light and

sive solutions,

limited sizes,’ the
company explain-
ed. Haveg fabricates to specific
requirements, even up to 30,000

Double Contact Plate
Freezer Introduced

KEY NO. G-226———

CHICAGO — Dole Refrigerating
Co. recently announced the new
“Freze-Cel,” a double contact plate
freezer.

Freezing mechanism consists of
vacuum cold plates, supporting
framework, liquid and _ suction
headers, flexible connections, and
hydraulic lifting mechanism all in
one assembly, mounted in an in-
sulated cabinet, Dole said.

Freezing mechanism alone is 4—

available for multiple installation
or if the cabinet is to be built or
purchased locally, the firm ex-
plained. The cabinet has doors
mounted front and back permit-
ting a “pass-through” type of
operation.

Models are available varying
from nine to 24 stations. Type of
refrigeration hook-up may be
gravity circulation, forced recircu-
lation, brine, or direct expansion,
it was added.

A safety feature is incorporated
to prevent excessive pressure
build-up in the hydraulic system
in event of abnormal expansion
of food packages during freezing.

Develop Thermostat for
Double-Pole Disconnect

KEY NO. G-227
ST. LOUIS—White-Rodgers Co.
recently offered a new electric
heat thermostat for localities that
require a double-
pole disconnect
switch placed at
each thermostat.

Type 1A63 con-
trol is specially
designed for use
on such electric
heating _installa-
tions as cable heat,
glass panels, elec-
tric baseboards, rubber panels,
and similar applications, the firm
said. It features a true “off’’ dial
position at which both sides of the
240 v. line are disconnected, and
no temperature change can close
the contacts.

A new sensitive element is used
which is said to obtain extremely
sensitive reaction to both radiant
heat and air temperatures. Even
the color of the element and case
is of a hue that has heat absorp-
tion qualities similar to that of
the human body, the firm stated,
to provide a close differential and
keep variations in heating panels
to a minimum.

This balancing of radiant tem-
perature with air temperature
maintains constant comfort and
provides the most economical op-
eration of the heating system, the
company declared.

The switching mechanism
mounts directly into any standard
2 by 3-in. outlet or conduit box.
This mechanism is said to be com-
pletely silent. Control has knob-
type temperature selector which
automatically maintains any tem-
perature from 55° to 85°. The
unit is rated at 5,000 w.

_Nonflammable Solvents

Won’t Harm Insulation

KEY NO. G-228———
WILMINGTON, Del.—Nonflam-
mable solvents that are said to
bite into and remove oil, grease,
and dirt without harming delicate
metal parts or electrical insula-
tion, yet are safe enough to use
in ordinary work areas with con-
ventional ventilating equipment
were recently made available by
E. I. du Pont de Nemours & Co.
Adaptable to vapor degreasing
or cleaning by liquid immersion,
the solvents are marketed by the
firm under its “Freon” trade-mark.
Three types, all “selective sol-
vents,” are available in container
sizes from 10 to 55 gal.
Nonflammable and non-explo-
sive, the solvents will not attack

insulation in motor wiring, the
company states. “Freon” MF,
with a boiling point of 75° F.,

“Freon” BF, which boils at 199°,
and “Freon” TF, whose boiling
point is 118° are the three sol-
vents available.

2-Stage Conditioner Ties In with Heating Unit

KEY NO. G-229

WICHITA, Kan.—‘“Polar Pak,”
a self-contained, two-stage air-
cooled air conditioner which may
be installed in an attic, crawlspace,
basement, or on a roof, was re-
cently announced here by the
Coleman Co.

Designed to deliver the required
amount of air for cooling when
tied into an existing forced air
heating system, the unit can be
installed independent of the heat-
ing system also. In the latter case,
air distribution is accomplished
through any one of three types of
duct systems—conventional sheet
metal with insulation, prefabri-
cated glass fiber, or the maker’s

* watch for the launching

pre-engineered 314-in. ducts with
air blending diffusers.

No refrigeration piping or
plumbing connections are needed.
Both the 2 and 3%-hp. models
have twin compressors for two-
stage cooling. A _ four-position
selector switch enables the system
to operate on one compressor with
the second cycling on the thermo-
stat, the producer pointed out.
Both compressors can be operated
when the load is heavy.

A switching arrangement is
used to keep the lower refrigera-
tion system in operation during
thermostat cycling to prevent re-
evaporation of condensate into the
conditioned space. The evaporator
blower has sufficient capacity to
deliver the required amount of air
for cooling at pressures up to
.45 in., the company said.

The 2-hp. Polar-Pak measures
46 by 30 by 21 in., has a capacity
of 23,800 Btu.h. The 3%-hp.
model is 50% by 34% by 21 in.,
with a capacity of 36,300 B.t.u.h.
Both of the models operate on 220-

Cladding Covers

Aluminum Impact

KEY NO. G-2210————

PITTSBURGH — Aluminum Co.
of America recently announced a
low-cost aluminum impact extru-
sion may be obtained with a thin
surface cladding which provides
cathodic corrosion protection, fa-
cilitates finishing, or makes join-
ing easier.

This will make feasible use of
aluminum impacts in such appli-
cations as water filters, small
water tanks, steam traps, electri-
cal cases, fittings for home hot
water heaters, and process indus-
try operations where _ corrosive
solutions or atmospheres are
severe, the company claims.

It is possible to clad high-
strength parts with an alternate
alloy suitable for all types of
finishing processes, it was added.

LaCrosse Upright Vendors Approved
By Several Soft Drink ‘Parent’ Firms

LA CROSSE, Wis.—Full ap-
proval of its coin-operated selec-
tive vendors has been obtained
from B-1 Beverage Co. of St.
Louis, Old Fashioned, Inc.,
Wilkes-Barre, Pa., Double Cola
Co. of Chattanooga, Tenn., and
Bubble-Up of Peoria, IIl., the
Vending Machine Div., La Crosse
Cooler Co. announced.

The firm further stated that
“practically all” the major
parent companies have approved
the line, particularly La Crosse’s
upright visual selective vendors.

What Parent Firms Are

A parent company, it was ex-
plained, produces its own type
of syrup and in turn franchises
various bottling companies who
are authorized to buy the neces-
sary ingredients and offer the
beverage in a particular sales
area.

It is to these parent com-
panies that associated bottlers
look for guidance, new informa-
tion on vending machine equip-
ment, and for field testing new
vendors before recommending
them to bottlers, according to
William A. Ebner of La Crosse.

It was indicated that produc-
tion facilities of La Crosse’s
Vending Machine Div. are being
rapidly expanded and improved.
At present four selective ma-
chines are available, and devel-
opment work is being com-
pleted on two additional up-
rights. These will offer five
flavors, the firm said, “and be
so arranged that the bottler has
absolute control over at least
50% of total capacity.”

Ebner reported that La Crosse
held a sales meeting immedi-
ately following the latest bot-
tler’s exposition at which the
field sales force was informed
of new equipment and promotion
plans for this year.

Speakers at the meeting
were: R. S. Denzer, president;
W. R. Trapp, vice president;
W. W. Newberry, secretary-

treasurer; Jack Horner, and
Ebner.
Explains Keyboard

System of Unit

During the meetings Denzer
explained the “unique” keyboard
system used in La Crosse up-
right vendors. The “release” is
“the heart of the system,” he
said. It is the controlling fac-
tor to operate individual gates
and is activated when the con-
sumer puts in a coin.

When the coin is inserted, he
pointed out, it drops down
through the mechanism to com-
plete the circuit to energize the
solenoid valve which cocks the
keyboard system opening each
individual gate.

At this point the purchaser
can remove the drink of his
choice by pulling one bottle for-

»>

ward. This automatically locks
other gates so only one bottle
can be removed at a given time.

Ebner said the company ex-
pects to advertise nationally in
bottling trade publications and
carry out a comprehensive direct
mail program this year.

Fogel To Put Up 51,000-Sq. Ft.

Bldg. To Replace

PHILADELPHIA—Fogel Re-
frigerator Co. announced that a
contract has been awarded to
William F. Lotz, Inc. to rebuild
the fire-destroyed sections of its
plant.

A 51,000-sq. ft. building will
be constructed to replace the
portions of Fogel’s plant which
were ravaged on Oct. 18 in a
spectacular $500,000 seven-
alarm blaze. The fire destroyed
two of Fogel’s seven buildings
and seriously threatened neigh-
boring homes and plants. The
ravaged buildings had housed
the company’s woodworking,
sheet metal, small parts storage,
and glass departments.

A new building had been ear-
marked for construction in 1958
as part of Fogel’s expansion
plans. However, the urgency of

Razed Units

replacing the lost buildings was
considered secondary to the
firm’s long-term needs.

Fogel and Lotz planned the
new structure so it can be ex-
panded further to meet future
growth. It will be built on a
1%-acre site now used as a
parking lot and will tie in with
present production on a straight-
line setup.

This new addition will en-
large the plant to over 150,000
sq. ft. of one-story manufactur-
ing space. A railroad siding
running inside the new building
and off-street truck docks will
facilitate loading and unloading.

The new structure, scheduled
for completion by late spring,
will house all ‘“‘metal’’ operations
(including storage, shearing,
forming, and finishing).

“SPACE-SAVER" compres-
sors, moving along conveyor
line at Kelvinator's Detroit
plant, are checked by
Charles H. Herrlich, sales
manager of the commercial

contract department and
T. J. Ammel, assistant sales
manager.

Kelvinator Retools To Increase New
Vari-Mount ‘Space-Saver’ Production

DETROIT — Kelvinator has
announced that its new “Space-
Saver” sealed compressor is
available now in quantity to
manufacturers of refrigeration
products for a variety of uses.

C. H. Herrlich, sales manager

of Kelvinator’s commercial con-
tract department, said the com-
pact compressor has received ex-
tensive testing in the laboratory
and field.

A comprehensive retooling
program including latest auto-

matic equipment, was com-
pleted during 1956 to provide
increased production.

Herrlich said the new com-
pressors “have the advantages
of light weight, compact design,
and low cost, yet are built to
the highest standards of quaiity
and dependability.”

The “Space-Saver’” compres-
sor is now available in nominal
14 and 4 hp. A %-hp. model will
be available later this year.
They are designed for refrigera-
tors, freezers, water coolers, re-
frigerated vending machines,
beverage coolers, and many
other refrigerated products.

Other compressors are avail-
able in 44, 4%, and %-hp. sizes
for applications requiring great-
er capacity.

“The ‘Space-Saver’ models oc-
cupy a minimum of space and
can be mounted in a variety of
ways,” it was stated. “Fewer
parts are used and stabilizing
and equalizing spring construc-
tion have been simplified. They

are exceptionally quiet in opera-

tion and economical to run.

A&P Cancels Outdoor
Vending Machine Use

LEVITTOWN, L. I, N. Y.—
Seven weeks after it began op-
erating a bank of five vending
machines outside its supermar-
ket here, A&P notified its cus-
tomers it was discontinuing the
service.

It was the giant chain’s first
outdoor vending machine trial
for dispensing foods at all
hours. Some customers had re-
ported difficulties, and critics
alleged that the units cut down
on in-store traffic. But A&P
wouldn’t say why it abandoned
the experiment.

Vari-Vend Co. of Chicago
made the machines. However,
Vari-Vend Sales, national dis-
tributor, said it had no knowl-
edge of the move.

Grand Union continues a
similar test in one of its mar-
kets.

Tie Incremental Periphery System In with Central System To Condition Bldg.

457 Through-the- Wall

Units Handle Upper

Floor Exterior Load

By George M. Hanning

NEW YORK CITY—One of
the first large office buildings
to be air conditioned by combin-
ing an incremental system
around the periphery with a
central system to handle the in-
terior zones is now being con-
structed at 72 Wall St. here.

The Remington Corp. incre-
mental system employs 457
“through the wall” individual
units to handle the exterior
heat load on the upper 10 of
the 15 floors of the building.
These units are tied in with the
perimeter steam heating sys-
tem of the building to provide
either heating or cooling at the
flip of a switch.

They are installed below the
windows on the exposed sides of
the structure and handle the
cooling and heating load to a
depth of about 16 ft.

2 Central Systems
Handle Interior Load

Two separate central systems
handle the interior zones on
these floors. They are designed
solely to remove the heat gen-
erated by internal sources—
such as people, lighting, and
business machines. This is a
fairly constant load the year
around.

One system, powered by two
Carrier 60-ton water chillers in
the basement, cools the sixth
through 11th floors. A single
120-ton Carrier water chiller
mounted on the roof, cools the
12th to 15th floors.

Originally, 72 Wall St., at the
corner of Pearl St., was a com-
bination bank and office build-
ing. The Seaman’s bank occu-
pied the first five floors of the
structure. It had its own air
conditioning system.

When it was decided to reno-
vate the building, it was also

AN exploded view of the Remington unit showing

decided to knock out the rear
wall and extend the building
through the block to Pine St.
As a result, the rear half of the
structure is new construction.
The Pine St. half is exposed on
all four sides, while one wall of
the old Wall St. building abuts
on an adjoining structure.

Retain 150-Ton System

Although the area formerly
occupied by the bank will be
converted to office space, the
bank’s air conditioning system
is being retained. The first five
floors of the new structure will
be occupied by a post office. This
will also have its own conven-
tional air conditioning system—
a 150-ton system divided be-
tween two Carrier 75-ton cen-

tral stations. >

All of the new air condition- |
ing equipment is being installed |
by Eugene J. Brandt & Co., Inc.,
Daniel Spiegel is engineering |
the installation for Brandt. |

The Remington incremental
system, though being installed
by Brandt, was sold by Burden,
French & Co., exclusive agent
for Remington in the metropoli-
tan New York City area. The
Carrier equipment was sold by
Brandt.

Elmer French, president of
Burden, French & Co., noted
that by combining the incre-
mental with the central system,
the building owners are realiz-
ing a big saving in installation
costs. Cost of the incremental

mercial Refrigeration
e for Residential and Auto-

@ for Household and Com- — = : 3 4 ,

is

i

system ranges from $450 to
$700 per ton, he said.

He pointed out that the in-
cremental system is carrying
about 60% of the total heating
and air conditioning load. By so
doing, it cuts down considerably
on the size of the central sys-
tem and ductwork needed.

Incremental System
Gives Individual Control

French asserted that the in-
cremental system gives indivi-
dual control at each unit. It will
not matter how the tenants
may decide to partition off their
floor space. They will always
have sufficient heating and cool-
ing available in each area, he
noted.

By connecting the existing

steam lines into the unit’s fin
coil heaters, each unit can op-
erate on either heating or cool-
ing without reference to any
other unit. The thermostatic
control on heating operates the
fan and the control on cooling
operates the compressor, he
said.

Each unit—of %4 or 1-hp. ca-
pacity—has its own compressor,
cooling coil, and air-cooled con-
denser assembly. Supply air is
drawn directly from the out-
doors and is mixed with recir-
culated room air.

To Keep Spare Units

A supply of spare units will
be maintained by the building
superintendent, French said. In

under the dash on all cars!

clutch and 3-speed blower!

15 minutes, he can remove a de-
fective unit and replace it with
a spare. Thus the tenant will
never need be without cooling
or heat.

At 72 Wall St., the John J.
Moran Co. holds the contract
for cutting through the exterior
walls. George A. Fuller Co.—J.
H. Taylor Construction Co., Inc.
is the general contractor.

Central System Operation

On the central system, all air
handling is through Buffalo
Forge Co. units. Three Lilie-
Hoffman cooling towers on the
roof conserve water pumped by
Weinman pumps. Minneapolis-
Honeywell Regulator Co. sup-
plied the controls.

Accelerated growth of packaged air conditioning, particularly in
the residential field, during recent years has been an important factor
in broadening the range of hermetic compressors. Bigger and bigger
sizes are being designed and manufactured.

Why this is happening is outlined in this article by Henri
Soumerai of Worthington Corp., who traces the development of the
hermetic or ‘‘seal-less’” compressor and goes on to explain numerous
design and application factors involved.

By Henri Soumerai, Worthington Corp.*

WORTHINGTON’S
ACCESSIBLE HERMETIC

At Holyoke we are building
at the present time accessible
hermetic compressors in sizes
from 2 to 74% tons. They are of
the horizontal single throw
crankshaft 2, 3, and 5-cylinder
types designed for both “Freon-
12” and “Freon-22” applica-
tions.

At equal displacement the
“F-22” machine will produce
about 57% more cooling capac-
ity than with “F-12.” Since the
actual horsepower input per ton
of refrigeration is practically
the same for both refrigerants
the horsepower requirements
and the mean pressure differen-
tial across the piston will also
be 57% greater than with “F-
22” than with “F-12.”

The motors are cooled by the
return gas. This method of cool-
ing is particularly efficient at
high suction pressures en-

countered in air conditioning ap-
plication for which these her-
metic compressors have been de-
signed. It also makes the motor-
compressor assembly quite in-
sensitive to air ambient tem-
peratures so that it is possible
to locate the motor-compressor
assembly even in a small un-
ventilated insulated space just
big enough to house the com-
pressor.

This is particularly important
in modern package air condi-
tioner applications. The typical
package air conditioner shown
with its front panel removed on
Fig. 6 illustrates this point. As
you can see, the compressor
compartment is quite small, and
with the unit front panel in nor-
mal position completely unventi-
lated.

DESIGN OBJECTIVES

The design of the compressor
naturally must be adapted to the
specific needs of the package air
conditioner. Taking all factors
in consideration we would list,
more or less in order of im-

portance, the following design
objectives:
(*) Long trouble-free life

As you know, package air con-
ditioners are being sold with a
full five-year warranty on the
refrigeration cycle. A lot of
people, even in our own indus-
try, do not fully appreciate
what this five-year warranty
means to the compressor manu-
facturer. Compare this guaran-
teed life with the life expectancy
of the modern automobile which
is often used as a yardstick of
industrial progress!

Most likely you will feel quite
happy if you can get about
50,000 to 100,000 miles of
trouble-free service out of your
engine. Taking a low average
speed of 25 m.p.h., this repre-
sents only 2,000 to 4,000 hours
of actual operation. In many
compressor applications on the
other hand, we expect over
4,000 hours per year or 20,000
hours of actual operation in a
five-year period.

In other words, these hermetic
compressors must be designed
with at least five to 10 times
more actual life built in them
than your automobile engine.
Similar comparisons with other
home appliances would be even
more convincing, but I believe
this single example explains
why “long trouble-free opera-
tion” figures on top of the list.

Incidentally, this comparison

materials solely on the basis of
automotive experience!

Naturally the design of the
compressor must conform with
recognized safety codes.

(b) Low Cost:

The package air conditioner
industry has become a very
competitive field. Initial cost is
of primary importance, particu-
larly in residential applications
where the industry is making an
all out effort to sell air condi-
tioning to the average home-
owner.

(c) Efficiency:

Efficiency, i.e., low power con-
sumption per unit of refrigera-
tion, will become more impor-
tant as the air conditioning in-
dustry reaches the average
homeowner. Together with effi-
ciency we should mention the
need of electric motors with
high power factors (over 85%)
to comply with present and
future utility rules. Lowest
practical inrush currents are
also desirable to prevent light
flicker on combined light and
power systems.

(d) Compactness, weight, and
shape

Of course, compactness and
light weight are desirable, but
it is even more important to
adapt the shape of the compres-
sor to the specific cabinet de-
sign. In our package air condi-
tioners the height and depth of
the compressor compartment
were the critical dimensions
whereas plenty of room was
available in the other direction
to provide sufficient air filter
and coil face area (Fig. 6).
Keeping this in mind we came
up with a shallow, narrow,
slightly “elongated” hermetic
compressor.

‘(e) Quietness

The elimination of objection-
able noises is an important fac-
tor in household and many com-
mercial air conditioning appli-

# | cations. Special emphasis is

laid on high frequency noise
levels which can be more ob-
jectionable than in the low fre-
quency bands. The compressor
should be at least as quiet as
other unit components.

(f) Accessibility:

Generally speaking, this is
not an important feature during
the warranty period as long as
replacements are readily avail-
able when needed. However, ac-
cessibility gains in importance
for the owner when units are
operating outside their warran-
ty period. Hermetic compressors
are successfully serviced in the
field by properly trained and
equipped service engineers.

TYPICAL DESIGN
FEATURES

Although more stress is laid
on certain design features, the
accessible hermetic compressor
is still basically a conventional
opening compressor with a
motor and sealed electrical ter-
minals added to it. For the
sake of brevity we shall confine
this discussion to those fea-
tures which differentiate a her-
metic from the open-type com-
pressor.

a 3-cylinder W-type 5-ton
“Freon-22” compressor, shows

charge strips.

following parts used on open-
type machines: mechanical seal
with its housing, flywheel, motor
sheave, belts, and two sets of
bearings. This results in a more
compact less expensive unit.
To this must be added an out-
standing feature of the gas-
cooled hermetic compressor: a
smaller motor frame size can be
used for a given output than
with a normal open-type air-
cooled electric motor. The rea-
son for this is that the cool re-
frigerant vapor on its way to

I! the cylinder intakes cools the

motor so efficiently that safe
winding temperatures are main-

™ | tained at extreme motor over-

loads.

Actually the nominal motor
horsepower has become so mis-
leading that most hermetic com-
pressor manufacturers stamp
full load and lock rotor currents
on their nameplates rather than
/nominal motor horsepower.

The absence of a belt drive
further eliminates a_ prolific
source of noise, reduces crank-
shaft stresses, bearing loads
and transmission losses. How-
ever, these advantages can be
-completely wiped out and dan-
gerously high bearing loads
produced by magnetic forces
when the rotor air gap is not
sufficiently uniform. This is par-
ticularly serious in the case of
motors designed with extremely
small air gaps. To assure per-
fect concentricity the main bear-
ing and stator bores are finish
machined in one operation.

A positive displacement ro-
tary oil pump feeds an ample
supply of oil to the main and
rod bearings through oilways
in the crankshaft. The lubricat-
ing oil is filtered by an oversize
fine mesh strainer before it
reaches the pump. A large oil
charge and low oil intake tube
make the unit quite insensitive
to normal oil losses in the sys-
tem. A relief valve maintains a
positive oil pressure constantly.

Gas vents are incorporated in
the lubrication system to assure
immediate priming after long
shut down periods when an ab-
normal amount of refrigerant is
mixed with oil in the crankcase.

FIG. 9—Here is the running gear of a
Worthington three-cylinder hermetic.

hermetic is removed to reveal

The complete running gear is
shown assembled in Fig. 9.

To assure long trouble-free
life under extreme operating
pressures and temperatures en-
countered on “F-22” air-cooled
condensing application we use
a forged steel crankshaft case
hardened on the main eccentric
and journals, with steel back
high lead bronze bearings. These
bearings are finish-bored in
place for close control of run-
ning clearances and concentrici-
ty. They are conservatively
sized for low bearing loads and
grooved in the unloaded areas
to flood the bearing with oil in
both directions of rotation.

The use of light weight alu-
minum rods and pistons, stati-
cally and dynamically balanced
crankshaft together with nearly
perfect alignment, uniform
motor air gap low lift valves and
large cast iron discharge mani-
fold are all factors which con-
tribute to a smooth quiet opera-
tion.

The oil pump of polyphase
hermetic compressors must be
able to supply oil to bearings

for clockwise as well as
counterclockwise rotation, i.e.,
the pump must be of the “re-

versible” type. The reason for
this requirement is that the
direction of rotation of a poly-
phase hermetic motor is not
readily visible at the time of in-
stallation and we have to make
sure of proper lubrication no

There's a Mighty Mite motor protector of the correct size
and dimension, as small as 34
practically any normal or special stator design up to a capa-

” long x 5/16” wide, to fit

city of Y% h.p., 115/230 volts.
Mighty Mite is a temperature sensing device which automatically
breaks the motor circuit whenever the operating temperature rises
above a safe limit. The Mighty Mite motor protector is accurately
pre-calibrated to “break” at any required temperature up to 200°C.
There is no further adjustment or handling necessary prior to instal-

Air Conditioned ‘Miracle Kitchen’ Has Central ‘Piped Cold’

Cooling Unit for Frost-Free Refrigerated Compartments

ST. JOSEPH, Mich.—A “third
dimension” in modern house-
keeping, remote and automatic
space control in the kitchen, is
the basic theme of an advanced
research project developed by
Whirlpool-Seeger Corp. engi-
neers.

Entitled the “RCA Whirlpool
Miracle Kitchen,” the exhibit,
which is completely functional,
has been designed to demon-
strate possible future mechani-
cal kitchen innovations that are
in various stages of develop-
ment in the Whirlpool-Seeger
engineering and research lab-
oratories.

“At the wave of a hand, a re-
frigerator moves down from a
wall cabinet to convenient
reach-in level,” it was pointed
out. “Temperature and humidity

are accurately regulated in each
compartment to provide ideal
conditions for preservation of
various foods. A fruit and vege-
table storage drawer glides out
from a base cabinet, as does a
similar freezer compartment.

INEXHAUSTIBLE
ICE SUPPLY

“Beverages may be stored at
proper serving temperatures in
bottles or in bulk. Hot or cold
liquids may be dispensed from
bulk storage compartments into
a drinking glass on contact with
an automatic tap. An inexhaust-
ible supply of clear ice, in any
size from large cubes to fine
powder, is dispensed in the same
manner.

In the spotless, filtered, air &

conditioned kitchen, illuminated
by indirect lighting, a self-pro-

pelled serving cart “will detach ™

itself from a dishwashing mech-
anism in the wall, move to a
dining table, deliver complete
table service or receive soiled
dishes, then return to its nest in
the wall to dispose of waste and
do the dishes. The entire opera-
tion is by predesignated control.

“The kitchen floor is kept
spotless by a mobile floor clean-
er which functions automatical-
ly on its own. Dispatched by
remote control, the ‘mechanical
maid’ disappears into a base

© cabinet recess when the scrub-

bing job is done. There it re-
charges itself with washing
agent and water for the next
cleaning operation.

“The floor cleaner may also
be used as a waxer and polisher.
Both the dishwasher cart and
floor cleaner are powered by
batteries which are automatical-
ly charged when the units are in
their respective wall niches.”

FOOD STORAGE SHELVES
LOWER FROM CABINETS

Operations which take place
automatically at the wave of a
hand include “food storage
shelves that are lowered from
wall cabinets to an accessible
level just a few inches above the
countertop, a utensil storage
drawer that glides open, a drop-
down storage rack for drinking
glasses, and a self-cleaning mix-
ing unit which will drop from
wall cabinet storage to counter
and mix, blend, grind, or shred
foods at selected speed and dura-

“Meal preparation is further
simplified by a wide range of

selected prepared foods from
cold storage to compartments
for cooling, warming, or cook-
ing. In addition to the meal
maker and the adjacent elec-
tronic oven is an electronic grill
for broiling meats and vege-
tables.

“Usable also as work surface
or dining bar, a surface cooking
range has a number of tiny
disks which will release energy
on contact with a specially de-
signed utensil. The cooking-
serving utensils are constructed
so that the exterior remains
cool while the food heats. An
electronic fan and air purifier
system draws grease, odor and
moisture from the air through
ventilating slots located behind
each thermostatically controlled
contact unit.

“The semi-circular range
wraps around the back of a
free-standing planning center
which is the heart and brain of
the RCA Whirlpool Miracle
Kitchen. On it are touch con-
trols for audio and visual com-
munication, food _ selection,
recipe selection, the mobile dish-
washer cart, the floor cleaner,
and the automatic meal maker.

room, or any other location 2—

about the house. A standard TV
broadcast may also be received.

“Expansive use of natural
materials, combined with archi-
tectural styling, presents in the
Miracle Kitchen a new concept
of kitchen color and design. Ac-
cented by colorful panels, rose-
wood base cabinets stand several
inches off the floor on slender
brass legs. The free-standing
cabinets are designed for easy
cleaning of the entire kitchen.

“Operated from the control

center,
from utilitarian white to cool
blue to warm pink providing the
psychological benefit of cool
lighting on a hot, humid day or

mood lighting ranges

warm lighting in cold, rainy
weather. Any combination of the
three colors may be selected.
Light is diffused by an arched
ceiling and soffits of translucent
vinyl.

COLOR RECIPES
PROJECTED ON WALL

“Other features of the kitchen
include color projection of
recipes on the wall, a large wall
projection surface for color tele-
vision reception, an inventory
panel that shows exact status
of food on hand and would ad-
vise the grocer of shortages,
and a canned food dispenser
which will deliver a can intact
or open it automatically, release
the contents, and destroy the
can.

“Elevator sinks are custom
adjusted to the height of the
user. Temperature and flow of
water are controlled by push-
buttons. When not in use, the
two sinks may be concealed
under counter-top panels.

“A current 1957 RCA Whirl-
pool appliance in an adjoining
laundry area is a new combina-
tion washer-dryer that washes
up to 10 lbs. of clothes out of
water by giving the clothes a
shower instead of 3 a a bath.” A

Air Conditioning & Refrigeration News, February 11, 1957

COMMERCIAL REFRIGERATION
SECTION STARTS MARCH 25

AND REFRIGERATION NEWS

IN AIR CONDITIONING

Commercial refrigeration design, financing, merchandising,
and installation will be given special emphasis in the new
once-a-month Commercial Refrigeration Section starting March

25, 1957.

The News recognizes in the growth of commercial refrigera-
tion renewed importance of the independent contractor-dealer.
He has amazing opportunities for profit as he establishes his
own importance in the distribution picture at an ever higher level.

Manufacturers need his improving concepts of store layout,
his better trained engineering and installation personnel, and
his solid backing of installations with adequate dependable
service.

So News editors will provide a concentration of stimulating,
dramatic news and feature articles in the new Section to help
more dealers do the “big job.”

In addition to this monthly section, all weekly issues will
continue to carry timely news of the field.

Commercial refrigeration manufacturers are invited to
take advantage of this new service with concentration of
advertising to tie in dramatically with the Section.

ACT NOW... Plan your advertising to support and

Al
&

influence these important men at the “business end” of
the distribution line—the contractor-dealers.

owned subsidiary of Dunham-
Bush.

A. G. Zumbrun, Sr., president
of Brunner Mfg. Co., will be-
come a vice president of Dun-
ham-Bush and will continue in
charge of the Utica and Gaines-
ville operations, according to
a Dunham-Bush announcement.
It added that two Brunner direc-
tors would be named to the
Dunham-Bush board.

Purchase of Brunner will per-
mit Dunham-Bush to sell all the
equipment for a complete air
conditioning or refrigeration in-
stallation, Cecil Boling, presi-
dent of Dunham-Bush stated. It
will open up broader sales op-
portunities in the lucrative in-
dustrial market, he told stock-
holders.

Sees $1.5 Million Net

Boling anticipates that after
the Brunner acquisition, total
annual sales would be approxi-
mately $40 million and net in-
come after taxes would be ap-
proximately $1.5 million or
about $1.27 per share.

He pointed out that Brunner’s
distribution parallels that of
Dunham-Bush in almost every
respect with more than 60% of
the outlets and users being iden-
tical.

“The number of companies
manufacturing compressors and
condensing units for air condi-
tioning and refrigeration is
limited and the potential for a
progressively and properly op-
erated company is great,” Bol-
ing declared.

“We are presently a substan-
tial user of Brunner machines.
Hence there would be a pur-
chasing savings.

“We can make (in fact, al-
ready do make) many parts that
can be used by Brunner in the

Directors Agree to Brunner Sale- -

assembly of their condensing
units, thereby materially reduc-
ing their cost of purchased ma-
terial per dollar of sale. An
analysis of their figures indi-
cates that this is one of their
pressing problems.

“Some of the items we make
and Brunner could use would
be condensers (air and water
cooled), bases for condensing
units, machined parts, sheet
metal fabrication, aluminum
foundry work, and_ control
panels.

Tells Potential Advantages

“Some other potential advan-
tages of the acquisition are sav-
ings in sales, advertising, ac-
counting, and purchasing; more
and better engineering for the
Brunner line of equipment; bet-
ter geographical locations for
warehousing for both com-
panies; and over-all strengthen-
ing of both Dunham-Bush and
Brunner as a dominant factor in
the air conditioning and refrig-
eration industry.”

Zumbrun, in a letter to Brun-
ner stockholders, said in addi-
tion: “We believe that Brun-
ner’s operations at Utica and
at Gainesville will profitably
expand at a rate even more
rapid than has been evidenced
during the past several years.

“Furthermore, it would ap-
pear that the combined opera-
tion would permit financing the
expansion of productivity of
plant and equipment.

“As you are aware from ma-
terial previously sent you,
Brunner is in great need of ad-
ditional finances to take ad-
vantage of growth potentiali-
ties.

“But ... the board has not
been able to arrange for addi-
tional long term and equity capi-
tal on terms deemed by the

Brunner stockholders were
also informed that the purchase
agreement has the support of
Fusz-Schmelzle & Co., St. Louis
broker. Fusz-Schmelzle last
summer solicited proxies among
Brunner stockholders in opposi-
tion to a proposal to sell Brun-
ner to Bendix-Westinghouse
Automotive Air Brake Co. The
proposal was defeated.

The letter to stockholders
said the Dunham-Bush offer, in
addition to the stock and de-
bentures, also would provide,
for each $100 in debentures, a
warrant for one share of Dun-
ham-Bush common stock at $12,
exerciseable for five years, it
was explained.

The letter said Dunham-Bush
is currently paying an annual
dividend of 60 cents per share as
compared with 30 cents per
share by Brunner.

Dunham-Bush was_ formed
last June through a merger of
Bush Mfg. Co. here with the
C. A. Dunham Co. of Chicago.

Bush, founded in 1907, manu-
factured commercial refrigera-
tion and air conditioning equip-
ment and heat transfer prod-
ucts.

Dunham, in business since
1903, made a line of heating
equipment.

Brunner started out in 1906
and is making refrigeration con-
densing units, packaged air
conditioning equipment, and air
compressors.

To Offer Full Line

Their combined production,
said the letter to Brunner stock-
holders, “would enable produc-
tion and distribution of one of

Air Conditioning & Refrigeration News, February 11, 1957

Servel Reduces Net

(Concluded from Page 1, Col. 5)
to $26,950,657 in 1956. Defense
product sales, principally air-
craft wings and components,
declined from $26,373,187 in
1955 to $15,714,714 in 1956.

Principal causes of the decline
in civilian sales, the report
points out, were unfavorable
industry-wide market conditions
for refrigerators, and the dis-
continuance of unprofitable
products. The decline in defense
sales was attributed chiefly to
the completion of major con-
tracts, and to cutbacks and
changes in government require-
ments.

The Servel report told of the
company’s decision to concen-
trate its production resources on
refrigeration and air condition-
ing products employing the ab-
sorption-type freezing system.
This system was first introduced
by Servel in its gas refrigerator
in 1926, it was noted.

Servel’s 1957 household re-
frigerators are operated by gas
or kerosene. The company’s
central-type “all-year’” air con-
ditioners operate on gas, oil, or
steam.

The report said an important
addition to the all-year air con-
ditioning line in 1957 “will be a
3-ton oil-operated model. This
unit, developed in cooperation
with two of the affiliates of the
Standard Oil Co. (New Jersey),
has already undergone extensive
field testing, and will be ready
for production-line manufacture
in 1957.”

Ruthenberg and Menzies re-
ported increased consumer in-
terest in the company’s automa-
tic ice-maker feature, which
freezes ice cubes without trays

Loss In '56--

and automatically stores the
cubes in a container for ready
use. In 1956, where purchasers
of Servel refrigerators had a
choice, 73 out of every 100
ordered models equipped with
the automatic ice-maker, it was
stated.

“A number of refrigerator
manufacturers are now testing
Servel’s automatic ice-maker for
possible inclusion in one or
more of their 1958 models,” the
report disclosed.

Regarding the company’s
“Wonderbar” portable refriger-
ette, the report said the Shera-
ton Corp. “has worked with
Servel engineers in designing a
special ice-maker Wonderbar to
be built into rooms and suites
of the new Sheraton-Dallas
hotel.”

A separate sales department
has been set up to exploit the
large potential market for the
Wonderbar, the report added.

During the 1956 fiscal year,
Servel continued its program of
contraction, aimed at “concen-
trating on products which have
traditionally contributed most
to Servel profits,” and at “re-
ducing the company’s facili-
ties and work force to a size
consistent with the current
needs of the business.”

The net effect of the program
of contraction, according to the
Servel report, will be “to re-
duce overhead and thus help the
company to become a lower-cost
producer, to improve the com-
pany’s cash position, and to pro-
vide cash for the acquisition of
profitable businesses and thus
take advantage of Servel’s
large carry-forward income tax
credit.”

Sees Egg Vendors Upping Sales--

(Concluded from Page 1, Col. 4)
grams of production, packaging,
and handling from the farm to
the retail store.”

He says it appears the grad-
ing of eggs may shift consider-
ably toward quality determina-
tion by sample candling or
breakouts, rather than through
candling of an entire lot.

“The development and use of
automatic, mechanical devices in
the field of egg grading will
greatly influence egg production
and marketing programs,” says
Bragg.

The specialist also notes that
because of a less seasonal varia-
tion in production and a fairly
uniform year-round demand,
“cold storage warehousing of
shell eggs may soon be almost a
thing of the past.

“However, the need for egg
cooling equipment on farms and
for vehicles in transit, as well
as for refrigerated storage of
frozen eggs, chickens, turkeys,
and ducks will probably con-
tinue to increase,” he said.

Bragg says the shift from

railroad to motor truck trans-
portation for eggs appears to be
almost complete.

He adds that there is a strong
trend toward greater use of
motor trucks in transporting
live and dressed market poultry

because of the reduction, in,

many instances, in the length of
time in transit.

There also is a greater per-
centage of deliveries made
direct to retail outlets by truck.

CORRECTION

A “minus” sign where a
“plus” sign should be will
make a lot of difference in the
formula given by John A.
Schenk, director of engineer-
ing for Alco Valve Co., for
figuring pressure at the ther-
mostatic expansion valve out-
let.

The formula appeared on
page 22 of the Feb. 4 issue in
Shenk’s article on thermosta-
tic expansion valve selection.
The correct formula is

I> E + (F + G + H)
where

E is compressor suction
pressure.

F is pressure drop in suc-
tion line due to friction

G is pressure drop in eva-
porator

H is pressure drop in dis-
tributor and connecting tubes

I is pressure at the thermo-
static valve outlet.

_ Adds Cold Storage Rooms

In Waynesboro Plant To
Hold Fresh Food at 31°

WAYNESBORO, Pa. — The
Waynesboro Ice & Cold Storage
recently completed an addition
to its plant on Cleveland Ave.,
it was announced.

This comprises two rooms, the
largest of which measures, in
round numbers, 134 by 88 by 21
ft. high. The other room is 45
by 44 by 21 ft. high. Combined,
they provide a total of 281,400
cu. ft.

The new storage rooms are
designed for holding apples and
other fresh foods. They have a
combined capacity of 75,000
bushels.

These rooms are held at 31°
F. by automatic controls. They

are cooled with 2,790 lineal feet ©

of 2-in. Frick “Prestfin’ pipe.
The fins are 7 in. square and
are spaced on 114-in. centers.

Both rooms are insulated with
“Styrofoam,” 4 in. being used on
the floors and walls, and 6 in.
on the ceiling, the company ex-
plained.

Typhoon Unveils ’57 Line--

(Concluded from Page 1, Col. 2)

Over-all size of the economy
model is 24 in. wide, 26 in. deep,
and 66 in. high. Cooling capacity
is listed as 244 tons and ship-
ping weight as 445 Ibs. It can
be installed for as low as $1,000
using ductwork or plenums.

The model is described as a
completely assembled package
unit, ready to set in place and
hook up to water and electricity.
An electric range-type plug-in
can be used on this unit, it was
pointed out. Ductwork connec-
tion is on top of the unit.

Hermetic compressor is avail-
able with one or five-year war-
ranty. ‘“Corrosion-proof Admi-
ralty metal condenser with mul-
tiple tube-in-tube design features
greater heat transfer surface,
uniform operation tempera-
tures,” the firm said.

According to Jobes, Prop-R-
Temp is a true heat pump and
differs considerably from a con-
verted air conditioner in appear-
ance and design.

“It offers as standard equip-
ment, Admiralty metal condens-
ers and all-copper cooling and
heating coils. New models are
more compact and offer higher
efficiency.

“A 1,000-sq. ft. house in the
north or south can be heated
and cooled for as low as $10 a
month average year-round with
our water-to-air equipment.”

Details on the various types
of units were announced:

“Water-to-air models are
available in sizes 21% to 12 tons
full hermetic, and 10 to 30 tons
semi-hermetic. On full hermetic
models the complete refrigera-
tion chassis can be exchanged
on the job in 30 minutes, and
carries a five-year factory war-
ranty.

able in 3 and 5-hp. models, now
in production. Custom built air
source heat pumps up to 20 hp.
are currently available.

“Water-to-water models, pro-
ducing warm and chilled water,
are available in sizes 2'5 to
40 tons.

A highly-competitive line of
packaged water chillers was
shown in sizes 242 to 40 tons.

A highlight of the school was
an evening open house party at
Typhoon’s new plant in Tampa
where visitors were greeted by
members of Tampa’s Committee
of 100 and Mayor Nuccio.

In another announcement, the
company reported that Florida
State Fair’s Electrical Exposi-
tion at Tampa Jan. 29-Feb. 9
had “perfect climate,” with
Prop-R-Temp heat pumps heat-
ing or cooling automatically as
temperature directed.

3 Big Producers Cut

Copper Price to 34£

NEW YORK CITY — Phelps
Dodge Corp. recently cut cop-
per prices 2 cents a pound to
34 cents and was immediately
followed by Kennecott Copper
Co. Anaconda Co., as was ex-
pected, then lowered its quota-
tion to 34 cents also.

Custom smelters reduced their
price for copper to 33 cents a
pound—a 1-cent cut—but trade
sources said sales at this new
quotation were small, with con-
sumers showing “little interest.”

Copper supplies are now
“adequate to meet demand,” said
Sir Ronald L. Prain, chairman
of Rhodesian Selection Trust,
Ltd. and Roan Antelope Copper
Mines, Ltd., speaking in New
York City. These producers cut
the price charged British con-
sumers for copper to 31%
cents a pound,

Copper continued to decline in
U. S. and foreign markets last
week as supplies remained
larger than demand. Consumers
were reported to be “disap-
pointed” by the 2-cent a pound
reduction, saying the cut wasn’t
“deep enough.”

Silco Products To Move Plant--

(Concluded from Page 1, Col. 3)

Engineers suggest that some-
times the agents (themselves
usually engineers) go too far in
drawing up plans for a contrac-
tor or owner.

Jobbers are often at odds
with the agents over who should
sell what. Both agree that
small items, such as pipe fit-
tings, are the province of the
jobber and that large units, such
as a 100-ton air conditioner,
can best be handled by an agent.
But they clash over the big lines
of equipment in between, it was
noted.

In sounding off on their com-
plaints, contractors’ revealed
they are often beset by a feel-
ing of uncertainty resulting
from “the generally unstabilized
situation throughout the indus-

problem of horizontal competi-
tion from other members of the
same group.

This, it is claimed, has re-
sulted in “profit-ruining price
cutting.”

Several indicated they agreed
with the comment of one agent
that the profit margin “has
been going to pot during the
last five or six years.’’ Competi-
tion is said to be rougher in the
southwest than perhaps any
other section due to the tre-
mendous influx of industry rep-
resentatives to get a share of
the southland’s booming busi-
ness.

However, no one is asking
that regulations be passed to
to solve industry problems. In-
dustry representatives took a
philosophical view of their

years of operation in Minnea-
polis, Cook said. The company
manufactures evaporative con-
densers, cooling towers, air
washers, dehumidifiers, air con-
ditioning units, and coils.

“The move is necessary to put
our customers in a better posi-
tion from a competitive stand-
point,’”’ Cook explained.

“Fully 90% of all shipments
made by us are to _ points
throughout the eastern and
southern part of the country.
At Fountain Inn, we will be
closer to the source of most of
our raw material and we will be
much closer to our points of
distribution.

“Both of these will not only

get shipments to them more
rapidly than before.

“Our present freight costs
have run close to 10% of the
value of our shipments, a prime
reason why this move is not
only advisable but absolutely
necessary.”

At Fountain Inn, Silco will
occupy a modern plant built es-
pecially for its operations,
which, according to Cook,
should reduce production costs
considerably.

“The new plant will be of
ample size for our expected
volume of business and will be
so constructed that unlimited
expansion is possible. It will be
equipped with modern ma-
chines and completely air condi-
tioned for the comfort of the
employes,” he said.
