Servo Friz SHC 400 is synthetic and high performance refrigeration compressor oil.It is synthesized from polyalphaolefin (PAO).It has high viscosity index and low pour point which allows lubrication at extreme conditions.It has excellent oxidation stability and low solubility with conventional refrigerants.Hence,used in refrigerants.It is mainly used in refrigeration compressors operating at very high temperatures and for systems with very low evaporator temperature. It is compatible with all refrigerants except SO2. It is used in compressors using refrigerants like ammonia and CO2. It should not be mixed with mineral oils.
