Application:

Shell Refrigeration Oil S4 FR-V 68 is a synthetic refrigeration compressor lubricant based on alkylated benzene technology. It is designed to meet the lubrication needs of compressors operating with most refrigerants—excluding HFCs—and is suitable for domestic, commercial, and industrial applications. Formerly marketed as Shell Clavus Oil AB, this product ensures optimal system operation and long maintenance intervals.

Performance Features & Benefits:

  • System Efficiency: High solvency promotes cleanliness and refrigerant performance.
  • Long Drain Intervals: Excellent oxidation stability and deposit control even under severe conditions.
  • Versatile Compatibility: Works with most sealing materials and fully miscible with mineral oils and synthetic blends.
  • Flushing Capability: Can be used for flushing turbine circuits due to solvency properties.

Main Application Areas:

  • Open, semi-hermetic, and hermetic refrigeration compressors
  • Rotary and reciprocating compressor designs
  • Refrigerant systems using R717 (ammonia), R744 (CO₂), R12, R22, and R290 (propane)
  • Turbine circuit flushing operations

Specifications & Approvals:

  • DIN 51503: KAA, KC

Environmental & Safety Information:

  • Avoid skin contact. Use impervious gloves when handling used oil.
  • Wash immediately with soap and water after contact.
