Manufacturer's description
Advanced Synthetic Refrigerator Compressor Lubricant. 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.
Applications
- Refrigerator compressorsShell 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. Because of its solvency power and compatibility with mineral oils it can be used as a flushing fluid in turbine circuits. For more information contact your local Shell representative.
Performance & benefits
- System efficiencyShell Refrigeration Oil S4 FR-V has high solvency and is designed to maintain refrigerant cleanliness and efficiency.
- Extended maintenance intervalsShell Refrigeration Oil S4 FR-V has excellent high temperature and oxidation stability providing long service life even where high compressor discharge temperatures are found. In addition it is formulated to provide excellent control of deposit and sludge formation resulting in extended oil drain intervals in comparison with mineral oil based refrigerator oils.
- Shell Refrigeration Oil S4 FR-V meets the requirements of DIN 51503 KAA and KC
- 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 0 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 S4 FR-V is completely miscible with mineral oil, other alkylated benzene and PAO based lubricants
Standards & approvals
DIN 51503 KAA
Refrigeration compressor oil KAA — DIN 51503
Class KAA of the German standard for refrigeration compressor oils: a mineral oil for ammonia plants, not miscible with the refrigerant.
