Refrigerating and Air Conditioning Compressors – Commercial
AN INTEGRAL HP COMPRESSOR (2 TO 3 HP), BY FRIGIDAIRE, possibly MODEL R, CIRCA 1942 – it would be representative of a new generation of open system refrigeration compressors for F12 refrigerant, which began to emerge in the late 1930’s. With a whopping 17 inch, twin V belt fly wheel, in formed and riveted steel plate, it followed the slow speed, high displacement compressor design idiom preferred by Frigidaire in the period. It would come to stand as an historic marker of the end of an epic era in refrigeration machinery engineering.
