Refrigerating and Air Conditioning Condensing Units – Commercial
Frigidaire’s model AW refrigeration machine exemplifies their engineering approach to what was referred to as “radiator type” condensing, as it was employed by the company on larger capacity condensing units [See also Model S and G, #046 – #048]. Using sulphur dioxide refrigerant, the Model AW would be seen in Canadian estate homes, institutions, food stores, diary bars and hospitality applications in higher capacity, fractional horsepower applications, well into the 1950’s. Then the clear preference of the industry and its publics swung heavily to the use of non-noxious refrigerants, Frigidaire, 1932.
Features:
The machine is equipped with Frigidaire’s floating motor mounting system, a distinctive contribution to the engineering of the period, now by-passed with a rigid mount. The modification stands as historic marker of frequency standardisation in Ontario, circa 1948, when all 25 cycle motors were removed to be replaced by 60 cycle.
