Specifications and Approvals
- Shell Refrigeration Oil S2 FR-A meets the requirements of DIN 51503 KAA and KE.
Applications
- Refrigerator compressors
Shell Refrigeration Oil S2 FR-A 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 S2 FR-A is recommended for use with ammonia (R717) based refrigeration systems where it offers excellent performance, even under high compressor discharge temperatures, or down to evaporation temperatures of -30°C.
It can also be used in systems using hydrocarbons such as propane (R290).
Shell Refrigeration Oil S2 FR-A is not recommended for use with CFC, HCFC or HFC refrigerants such as R12, R22 or R134a.
Shell Refrigeration Oil S2 FR-A is compatible with all commonly used sealing materials designed for use with mineral oils.
