Refrigerator Compressor Lubricant

Refrigeration compressor oil

Shell Refrigeration Oil S2 FR-A is a compressor oil characterized by low miscibility with the agent and is intended for use in systems containing ammonia as a refrigerant. The combination of base oil containing appropriately refined paraffin oils with specially selected additives minimizes the formation of deposits in the system and ensures long service life of the oil and the device.

Application:

• Refrigeration compressors
  Shell Refrigeration Oil S2 FR-A is recommended for use in open, semi-hermetic and hermetic applications in domestic, commercial and industrial systems. It can be used in reciprocating and rotary compressors.
• Refrigerant Compatibility
  Shell Refrigeration Oil S2 FR-A is recommended for use in ammonia (R717) filled systems where it provides excellent performance even at high compression temperatures and low evaporating temperatures as low as -300C.
  It may also be used in systems using hydrocarbon refrigerants 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.

Features and benefits

• System efficiency
  Shell Refrigeration Oil S2 FR-A is an oil with optimum performance for systems with an oil separator. It is designed to reduce oil entrainment, which reduces the tendency to thin the oil and reduces oil retention on the internal surface of the evaporator, allowing for increased system efficiency.
• Extended runs
  Shell Refrigeration Oil S2 FR-A has exceptional resistance to high temperatures and oxidation, which ensures long oil service life, even at high compression temperatures. In addition, the oil provides better protection against deposits and sludge formation during long service compared to conventional refrigeration oils made from mineral bases.
