Shell Refrigeration Oil S2 FR-A 68 is a premium refrigeration compressor lubricant, designed for use in systems utilizing ammonia (R717) or hydrocarbon refrigerants like propane (R290). Formulated with refined paraffinic base oils and advanced additives, it ensures system efficiency, extended maintenance intervals, and reliable operation even in extreme temperatures.

Key Features & Benefits

• System Efficiency
  • Reduces ''light-end'' oil carryover, preventing oil thickening and minimizing evaporator surface coating.
  • Ensures consistent performance and optimized energy efficiency.
• Extended Maintenance Intervals
  • Excellent high-temperature and oxidation stability.
  • Minimizes deposit and sludge formation, extending oil drain intervals compared to conventional mineral oils.
• Broad Temperature Range
  • Performs reliably under high compressor discharge temperatures or down to evaporation temperatures of -30°C.
• Refrigerant Compatibility
  • Fully compatible with ammonia (R717) and hydrocarbon refrigerants like propane (R290).
  • Not suitable for CFC, HCFC, or HFC refrigerants such as R12, R22, or R134a.

Main Applications

• Refrigerator Compressors:
  Suitable for open, semi-open, and hermetic compressors in domestic, commercial, and industrial systems.
• Rotary and Reciprocating Compressors:
  Engineered for use in both types of compressors.
