Complete Refrigeration With One Frigidaire Unit.
The application of mechanical refrigeration to soda fountains required
considerable study, many experiments and much caution. Mechanical re-
frigeration in itself was nothing new and had been in commercial use
for many years. However, its application to the soda fountain at once
brought out the difficulty of supplying the many temperatures needed for
the successful operation of these fountains with one refrigerating unit.
In designing the Guaranty fountain in its simple and practical way to
secure the five necessary temperatures, the engineers have scored a com-
plete triumph.
The many months spent in experimenting, simplifying and in other
ways adding to the all-around efficiency of this type of fountain, resulting
in the 100 per cent, mechanically refrigerated Guaranty, was well worth
while. The operation of thousands of these fountains in every-day use
has <strong>complete</strong>ly demonstrated not only Guaranty's ability to serve supremely
well and economically, but also to deliver many years of continuously
satisfactory service.
Maintaining Five Correct Temperatures Automatically.
The Guaranty soda fountain is constructed in a simple and practical
way to secure the five necessary soda fountain temperatures.
The soda and city water coolers and the Frigidaire boiler, located in
the first, or cooling chamber, are immersed in a water bath as shown
more clearly in the sectional view. Fig. 199. The temperature is auto-
matically maintained at approximately 33° F. by a regulating control valve.
The dry storage refrigerator is located second from the left in which
a temperature ranging from 40° to 45° F. is maintained. This compartment
is equipped with a sliding shelf, thus providing double-deck arrangement
for bottle goods. Refrigeration for this compartment is secured
through a semi-insulated partition from the cooling compartment.
On the extreme right is located the brick compartment, where a
