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 

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

Fountain Inn, S. C., George E. 
Cook, president, announced re- 

“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-

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- 

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- 

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- 

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.

1955, it is reported by Geo. S. 
Jones, Jr., managing director 
of the Air-Conditioning & Re-

Egg Vendors 

Upping Sales 

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

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.

Agreement for the purchase of 
all assets of Brunner Mfg. Co. 
by Dunham-Bush, Inc. was ap- 
proved recently by the boards of 
directors of both companies. 

Stockholders of both firms 
will vote on the agreement 
March 6. If they approve, the 
sale will be closed on March 29. 

The agreement provides for 
the assumption of all Brunner’s 
liabilities and the issuance of 
14 share of Dunham-Bush com- 
mon stock and $6 of new non- 
convertible 6% 20-year subordi- 
nated debentures of Dunham-

stock of Brunner issued and 
outstanding at the closing date. 

Under the agreement, Brun-

reduced its operating loss, ac- 
cording to the annual report to 

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

fiscal year, and a net loss of $8,- 
157,766 for the 1954 fiscal year. 
The 1956 results are after inven- 
tory write-offs amounting to

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- 

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- 

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-

here. Officials said the new fa- 
cility will be used for receiving 
incoming parts for air condi-

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- 
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-

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 




When you buy a low 

temperature system and 
check the TOTAL costs of both

you'll be pleased to find that 


CosTsS NO MORE...

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 

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 

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 

“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-

Hanson, Inc. has set its annual 
“first-of-year” sales sessions to 
coincide with the International 
Heating and Air Conditioning 
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-

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

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

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- 

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- 

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 

“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

used to air condition the insti- 
tution before the next “hot” 

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. 

Air Conditioning & Refrigeration News, February 11, 1957 

NEW line of hermetic com- 

pressors ranging from 10 

through 60 hp. has been 

introduced by Carrier Corp. 

This 15-hp. model is said 

to be virtually vibrationless. 
and noise-free. 

Hermetic Reciprocating Refrigeration 

Units Up to 60 Hp. 

SYRACUSE, N. Y.—A reduc- 
tion in the cost, size, and weight 
of “built-up” air conditioning 
systems for smaller buildings 
was forecast recently by Carrier 
Corp. with the introduction of 
a new line of hermetic recipro- 


Intricate piping in confined space can be insulated easily with Armstrong Armaflex. 
simplifies handling, reduces application time as much as 50% when compared with wrap-on type coverings. 

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. 



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. 

Send for free booklet giving full details on this amazing new insulation. 
Write Armstrong Cork Company, 3002 Parsons Street, Lancaster, Pa. 



Fast, easy fabrication of fitting covers 
is accomplished by miter-cutting pieces 
of Armaflex and cementing them to- 
gether with Armstrong 520 Adhesive. 

Extreme flexibility 

Prevents condensation when used 
within recommended temperatures and 

Armstrong Armaflex seals out air and 
moisture, eliminates need for separate 
vapor barrier coating or finish.

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. 


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.” 


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- 

To Cool Branch Banks 

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 

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.

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 
heat exchanger by a 110 g.p.m.

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 

“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 

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 

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 

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 

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. 


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. 


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. 

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

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- 

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, 

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 

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

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

Abandoned Ice Box 
Claims 2 More Tots 

SAN ANTONIO—Two young 
children died here recently after 
being trapped several hours in 
one of three abandoned ice boxes 
in their yard, it was reported 

Grover Earl Emery, 5, and 
his sister, Ellen Irene, 4, were 
missed by their father, who 
works nights, when he awoke 
about 3 p.m. 


Because of its ease of operation, ex- 
treme sensitivity and immediate indica- 
tion of a leak, the new Type H-1 leak 
detector has played an important part 
in increasing production of packaged 
air conditioners at the General Electric 
Company, Bloomfield, New Jersey. 

Using the detector, a company em- 
ployee can completely and accurately 
test a unit in a matter of minutes, pin- 
pointing leaks for quick repair while 
the units are still on the assembly line. 
The detector has thus helped General 
Electric substantially increase produc- 
tion yet maintain a high product 

Air conditioning and refrigeration 
contractors are also using G.E.’s leak 
detector to assure leak-tight installa- 

QUICK AND ACCURATE leak checks of equipment can be made on the assembly 

tions and to cut service costs. 



line as well as at customer’s installation. 


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.

Inside Dope 


(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- 

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 

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 

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 

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 

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- 

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- 

Those few examples of auto- 
mation in factories ‘“Dope’’ has

Inside Dope Space Heating Discussion To Lead Power 
Conference Talks Mar. 27-29 In Chicago

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- 
vances thus far. Hence, hopes 
for peace abound. 

How To Guide Your 

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- 

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 

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, 

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 

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-

Commercial Distributor’s Customer Services Are Varied 


Firm Is Prepared To Select Market Site, Estimate Potential, mm Ss 
Lay Out Entire Store, and Even Handle Problems of Financing 7 we 

a a 

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- 
fixture field, this company does Directing the activities of the ence was in the grocery field, a

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- 


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

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 


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 


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-

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 

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 


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 

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.

Here are some of the special 
features of the renovation:

total area of 17,000 sq. ft. and 
is a unit in a shopping center 
located in a suburban area. It 
is completely 100% self-service 
and is doing a weekly volume of 
over $40,000. 

Unitized System Feature 

Big feature of this market is 
the unitized system employed in 
the produce department—a pre- 
packaging operation that is 
seldom seen in the area. 

The produce department was 
laid out like the meat depart- 

preparation area and the latest 
type of set-up and equipment 
for packaging produce is used. 

This market is all McCray 
equipped and consists of: 52 ft. 
of fresh meat cases, in line with 
22 ft. for frozen meats, without 
superstructures for rear load- 
ing; 33 ft. of adjustable shelf 
dairy cases; 66 ft. of a new type 
of low back produce cases de- 

signed for the rear loading of — 

packaged produce; 58 ft. of 
frozen food cases with shelf for 
related items in a low super- 
structure; and 22 ft. of ice 
cream cases. 

The coolers installed include: 
meat, 12 ft., 5 in. by 35 ft. 5 in., 
by 8 ft 6% in.; produce, 8 ft.

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 

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- 

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- 

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 

(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 



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 

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- 

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 

(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 

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- 

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. 


That was almost double the previous record 

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

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.

First of all let me tell you 
how much I have always en- 
joyed reading your magazine. I 
look forward to its arrival 
every week. Besides having one 
of the largest air conditioning 
companies over this side, we 
also have a separate organisa- 
tion for teaching selling. 

I have written many hundreds 
of articles on this subject over 
the last 22 years, and I am now 
compiling a book comprising the 
best of these articles. I should 
like to include in this book an 
article I read in your magazine, 
and I am enclosing a copy of it. 
May I have your permission to 
use this article please?

the type of work he wrote about. 
I’ve had resident training in

pleted a correspondence course.

military were the only ones 
plagued with the problems that 
exist between Architects, Engi-

that through that article some- 
one will push the button to start 
the machinery rolling to allevi-

Now George, you hit on a

sure that there are a few ques-

Don’t miss the boat on the 

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 

Enjoy a relaxing, bracing ocean trip, the finest 
cuisine, a visit to sunny Nassau, “the Crown 
Jewel of the Golden Bahamas,” tour picturesque 
Jamaica, see the exotic sights of colorful Havana, 

“the Paris of the Western World.” 
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. 

No pierda el barco! 
means “don’t 

me Ps 
™ 4 
ag) OAS I 

Commercial Air Conditioners, Applied Systems, 
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. 
Air Conditioning wherever he’s located. And judging 
from the potential market for air conditioning, his future 
growth and success are unlimited.

What’s New 

Motorless, Pumpless Carbonator Introduced 


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

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.

Double Contact Plate 
Freezer Introduced 

KEY NO. G-226——— 

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

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 

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 


= oe f 

* 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.

Air Conditioning & Refrigeration News, February 11, 1957 

DURING a vending machine 
division sales meeting, R. 
S. Denzer, president of 
La Crosse explains the key- 
board system used on the 
firm's upright vendors. 

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 

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 
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 

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

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-

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.

Refrigeration’s Importance 

Emphasized In Montreal Ad 

MONTREAL, Que., Can.—The 
importance of refrigeration in 
modern supermarket operation 
was emphasized by Steinberg’s

and diversified 


Said ad copy: “Hold your 
hand over any fresh or frozen 
food counter at Steinberg’s and 
feel the blanket of cold air that 
covers the products. 

“This cold air comes from 
special compressors that work 
for you 24 hours a day. If we 
were to use ice, we would re- 
quire six and a half million 
pounds each day to generate 
enough cold air to maintain the ® 
freshness and quality of our 
perishable products and our 
frozen foods. 

“Every one of our markets is 
equipped with approximately 20 
compressors which supply cold 
air to counters and cooling 
rooms in the store. Our ware- 
house has similar compressors. 

“This tremendous refrigera-

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 

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 

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

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 |

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 

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

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

other unit. The thermostatic

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

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.* 


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- 

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- 

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- 


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 
(*) 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 
between the life of an automo-

materials solely on the basis of

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- 

(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 

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 

‘(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. 


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-

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- 


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.

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- 

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 
matter how the power leads are 

connected to the compressor | |

FIG. 11—Oil pump must be reversible to insure compressor lubrication regardless of 
direction of motor rotation. 

shown assembled in the crank- 
case with pump cover removed 
in Fig. 10. The basic reversing 
mechanism is illustrated in Fig. 
11, The pump rotor is driven by 
the compressor’ crankshaft; 
spring forces, oil pressure, and 
centrifugal forces keep the 
vanes in contact with the nor- 
mally stationary eccentric. 

The chamber formed between 

two consecutive vanes increases 
in volume on the right hand, 
i.e., suction side and decreases 
on the left hand, i.e., discharge 
side of the pump. The eccentric 
swings 180° with each change 
of rotation to maintain the pro- 
per oil flow towards the crank-

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- 

lation in the motor stator. 

Once installed, Mighty Mite provides continuous and automatic pro- 
tection to the motor against overheating due to mechanical overload, 
voltage variation, or any other cause. 

The Mighty Mite protectors illustrated above are actual size, and are 
only a few of the standard models available. Leads on terminals are 
furnished to individual requirements, and all Mighty Mites are pack- 
aged “ready-to-use” on your production assembly line.

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- 

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- 

“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. 


“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

centers throughout the kitchen,

Air Conditioning & Refrigeration News, February 11, 1957 

Seeger engineers call the new 7 ~ 

cooling method ‘piped cold.’ ”’ 

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.” 


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- 
tion. Part of this unit is remov- 
able for use as a portable, self- 
powered mixer. 

“Meal preparation is further 
simplified by a wide range of 
self-cleaning, automatic cooking 
facilities. An oven with automa- 
tically controlled time and elec- 
tronic energy descends to 
counter level for easy accessi- 
bility and rises again for ultra- 
fast cooking. A menu selection 
control at the planning center 

AT the press of a button or 
wave of the hand, several 
operations take place auto- 
matically in RCA Whirlpool's 
new “Miracle Kitchen." 

will activate a completely auto- 
matic meal maker which moves 
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- 

“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. 

“At the planning center, a 
rotating TV monitor, visible 
from any point in the room, 
shows at a glance activity at 
the front door, nursery, game 

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 

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 


“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 

“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 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 

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 


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

owned subsidiary of Dunham- 

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- 

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- 

“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 

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-

board advantageous to Brunner 
primarily because of the pres- 
ent condition of the money mar- 

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- 

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

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

To Offer Full Line 

Their combined production, 
said the letter to Brunner stock- 
holders, “would enable produc- 
tion and distribution of one of 
the most complete lines of heat- 
ing and cooling equipment avail- 
able in the market.” 

Dunham-Bush has plants lo- 
cated here and in Brewster, 
N. Y., Croton Falls, N. Y., 
Riverside, Calif., Michigan City, 
Ind., Marshalltown, Iowa, Toron- 
to., Ont., Can., and London, Eng- 
land. They utilize approximate- 
ly 758,000 sq. ft. of plant area 
and employ 1,344 persons. 

Brunner has plants at Utica, 
N. Y., and Gainesville, Ga., con- 
taining 215,000 sq. ft. of area 

and employing 600 persons, it ; 

was added.

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- 

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 

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 

“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 

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 

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 

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.

3 Big Producers Cut 

Copper Price to 34£ 

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.”

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 

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 

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- 

However, no one is asking 
that regulations be passed to 
to solve industry problems. In-

“The move is necessary to put 
our customers in a better posi-

“Fully 90% of all shipments
