Sunfriz oils are fully synthetic, environment friendly refrigeration oils which 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 fewer deposits. These oils meet IS: 4578-1989 specification. Sunfriz 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.
