Refrigerating and Air Conditioning Compressors – Commercial
A FRACTIONAL HP, TWIN CYLINDER COMPRESSOR FOR SMALL COMMERCIAL APPLICATIONS, Universal Cooler, Type DD, CIRCA 1952 – engineered and manufactured by a principal, original equipment manufacturer [OEM] of refrigeration machines during Canada’s “golden”, growth years of the industry. Representative of a new, mid 20th century, generation of smaller higher speed, open system compressor design for F12 refrigerant, it too would appear ubiquitously in the then rapidly expanding network of food stores and confectionery applications across Canada.
