Refrigerating and Air Conditioning Compressors – Commercial
A FRACTIONAL HP, COMPRESSOR FOR SMALL COMMERCIAL APPLICATIONS, PAR, MODEL SM,CIRCA 1949 – This compressor, similar in outwards appearance to the Par SL [see #3109], was also to be found on the company’s open market refrigeration condensing units, widely available through refrigeration wholesalers in the middle years of the 20th century. Unremarkable in many ways, it would find its way in a number of small “designer built”, trade, applications, including farm milk coolers.
Industrial Significance:
The open market manufacturers of refrigeration machinery of the period [such as Tecumseh Par and Bruner] would be a critical component of the Canadian refrigeration industry. They would be the direct line of equipment supply to the network of small, independent refrigeration mechanics that emerged by mid century. Their products, not tied to dealerships or franchises, would be found in a myriad of small applications such as farm milk cooling, in what was then a largely rural population of small, independent milk producers across Canada.
During this period Par equipment was marketed in Canada through R and E Thermal controls [Railway and Engineering], through their net work of operations across Canada
The Lynch Corporation, would go on to build a serviceable hermetic motor compressor, with much appeal to the trade, for its serviceability
