Refrigeration Compressor Oil is based on extremely low wax naphthenic oil for use where an uninhibited oil is required. It is recommended for use in refrigeration compressors using
ammonia, CFC (chlorofluorocarbon) and HCFC (hydrochlorofluorocarbon)
refrigerants such a R-11, R-12, R-13, R-113, R-114,
R-115, R-22, R-123, R-141b, R-142b, R-717, R-500, R-501 and R-
502. It is not recommended for use with HFC (hydroflurocarbon)
refrigerants such as HFC-134a (R-134a).
Whitmore’s Refrigeration Compressor Oil is recommended for
systems where the evaporator temperature ranges down to
approximately -35°F or -37°C.
