Shell Refrigeration Oil S2 FR-A is a low miscibility lubricant for compressors for use in ammonia refrigeration compressors. It is formulated with specially refined paraffinic base oils in combination with additives selected to minimize deposits in the system and ensure a long service life
- Refrigerant compressors
Shell Refrigeration Oil S2 FR-A is recommended for use in hermetic, open or semi-open compressors in domestic, commercial and industrial refrigeration systems. It can be used in both rotary and alternative compressors.
• Compatibility with fluids
Shell Refrigeration Oil S2 FR-A is recommended for use in ammonia refrigeration systems (R717) where it offers excellent performance even at high compressor discharge temperatures or at low evaporator temperatures below -30 ° C. It can also be used in systems that use hydrocarbons such as propane (R290)
Shell Refrigeration Oil S2 FR-A is not recommended for use with CFC, HCFC or HFC fluids such as R12, R22 or R134a.
• Compatibility with gaskets
Shell Refrigeration Oil S2 FR-A is compatible with all sealing materials commonly used with mineral oils.
• Compatibility with lubricants
Shell Refrigeration Oil S2 FR-A is completely miscible with mineral oils, and alkylbenzene and PAO based lubricants.
