Servofriz S oils are premium lubricants having low pour point and meet the lubrication requirement of reciprocating and rotary refrigeration compressors. Servofriz S oils are compatible with R-22 refrigerant. These products are recommended for use with all fluorocarbon refrigerants and with hydrocarbons and ammonia in refrigeration and air conditioning applications where the evaporation temperatures are lower than the pour point of the oil.
