Refrigerator Compressor Lubricant

Refrigeration compressor oil

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

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) systems where it provides excellent performance even at high compression temperatures and low evaporating temperatures as low as -30°C.
  It can also be used in systems with hydrocarbon refrigerants such as propane (R290). Shell Refrigeration Oil S2 FR-A is not recommended for use with CFC, HCFC or HFC type refrigerants such as R12, R22 or R134a.

Features and benefits

• System efficiency
  Shell Refrigeration Oil S2 FR-A is the optimum performance oil for oil separator systems. It is formulated to reduce oil entrainment, which reduces the tendency to thin the oil and reduces the amount of oil left on the internal surface of the evaporator to increase system efficiency.
• Extended runs
  Shell Refrigeration Oil S2 FR-A has exceptional heat and oxidation resistance, ensuring long oil life, even at high compression temperatures. In addition, this oil is more effective in protecting against the formation of deposits and sludge due to long use compared to conventional refrigeration oils made from mineral bases.
