Servofriz oils possess high fluidity at very low temperature, resist deposit formation and have reduced tendency to foam. These oils ensure high condenser efficiency and reduced compressor valve maintenance due to less deposits. These oils meet IS:4578-1997 (Ra 2004)specification. Servofriz 68 also meets Carrier Corporation, U.S.A. specification PP 46-1. Servofriz oils are recommended for a wide range of refrigeration compressors using all conventional refrigerants (CFCs) except sulphur dioxide and are suitable for both reciprocating as well as rotary compressors.
