Advanced synthetic lubricant for refrigeration compressors
Shell Refrigeration Oil S4 FR-V is a synthetic lubricant based on alkylbenzene. It offers a universal solution to the lubrication requirements of the majority of refrigerant compressors and is compatible with all fluids commonly used except HFCs.
Shell Refrigeration Oil S4 FR-V is suitable for use in hermetic, semi-open and open compressors in doemstical, commercial and industrial refrigeration systems. It can be used in both rotary and alternative compressors
Compatibility with fluids
Shell Refrigeration Oil S4 FR-V is suitable for use with the main refrigerant fluids: Ammonia Systems (R717) where it offers excellent performance, even at high compressor discharge temperatures or at -33 ° C low evaporator temperatures or lower.
Carbon dioxide systems (R744).
CFC and HCFC systems (R12e R22)
Hydrocarbon systems such as propane (R290).
Compatibility with gaskets
Shell Refrigeration Oil S4 FR-V is compatible with all sealing materials normally used with mineral oils.
Compatibility with lubricants
Shell Refrigeration Oil S4 FR-V is completely miscible with mineral oil, other alkylbenzenes or PAO based lubricants.
Specifications and Approvals
Shell Refrigeration Oil S4 FR-V meets the requirements of DIN 51503 KAA and KC.
