Lubriplate® refrigeration compressor oil 68-N is a highly refined naphthenic oil formulated for use in refrigeration compressor systems utilizing ammonia, CFC (chlorofluorocarbon) and HCFC (hydrochlorofluorocarbon) refrigerants such as R-717, R-11, R-12, R-13, R-113, R-114, R-115, R-22, R-123, R-141b, R-142b, R-500, R-501 and R-502. Lubriplate® refrigeration compressor oil 68-N is essentially wax-free as shown by its low pour point and floc temperature. It will not wax-out under low temperature conditions typically encountered in most systems. Equipment lines, evaporator, expansion valve and refrigerant control devices stay clean allowing for maximum system efficiency. Lubriplate® refrigeration compressor oil 68-N is also chemically and thermally stable which minimizes the formation of harmful varnish, gum and sludge deposits.
