Shell Refrigeration Oil S4 FR-V is a synthetic refrigeration lubricant based on alkylated benzenes. Compatible with all commonly used refrigerants with the exception of HFCs. They are particularly recommended for refrigerator compressors operating with ammonia and HCFC as refrigerant.
Shell Refrigeration Oil S4 FR-V is recommended for use in open, semi-open and hermetic compressors in domestic,commercial and industrial refrigeration systems. It can be used in both rotary and reciprocating compressor types.
Shell Refrigeration Oil S4 FR-V is designed for use with mostcommonly occurring refrigerants:
Ammonia (R717) systems where it offers excellent performance,even under high compressor discharge temperatures or down to evaporation temperatures of -33°C or lower.
Carbon dioxide (R744) systems.
CFC and HCFC systems (R12 and R22).
Hydrocarbon systems such as propane (R290).
Shell Refrigeration Oil S4 FR-V is compatible with all commonly used sealing materials used with mineral oils.
Shell Refrigeration Oil S2 FR-V is completely miscible with mineral oil, other alkylated benzene and PAO based lubricants.
