Oil for refrigeration compressors comes in the ESPRO SEECOOL N 68 grade. In order to ensure low pour point, dryness, and strong chemical stability, the grade is made from carefully chosen deep hydro finished lube base stocks. It is advised for a variety of ammonia and carbon dioxide-using refrigeration compressors, including reciprocating and rotary models. R-12, R-22, and other Freon refrigerants should not be used, according to the advice.
