Specifications and Approvals
- Shell Refrigeration Oil S4 FR-V meets the requirements of DIN 51503 KAA and KC
Applications
Shell Refrigeration Oil S4 FR-V is a synthetic refrigeration lubricant based on alkylated benzenes. It offers a universal solution to the lubrication requirements of most refrigeration compressors and is compatible with all commonly used refrigerants with the exception of HFCs.
- Refrigerator compressors
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.
- Refrigerant compatibility
Shell Refrigeration Oil S4 FR-V is designed for use with most commonly 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).
- Seal compatibility
Shell Refrigeration Oil S4 FR-V is compatible with all commonly used sealing materials used with mineral oils.
- Lubricant compatibility
Shell Refrigeration Oil S2 FR-V is completely miscible with mineral oil, other alkylated benzene and PAO based lubricants.
