Shell Refrigeration Oil S4 FR-V 32 Formally Shell Clavus oil AB

Advanced Synthetic Refrigerator Compressor Lubricant

Shell Refrigeration Oil S4 FR-V is a synthetic refrigeration lubricant based on alkylated benzenes. It offers a universal solution to the lubrication requirements of most refrigeration compressors and is compatible with all commonly used refrigerants with the exception of HFCs.

PERFORMANCE FEATURES

SYSTEM EFFICIENCY

• Shell Refrigeration Oil S4 FR-V has high solvency and is designed to maintain refrigerant cleanliness and efficiency.

EXTENDED MAINTENANCE INTERVALS

• Shell Refrigeration Oil S4 FR-V has excellent high temperature and oxidation stability providing long service life even where high compressor discharge temperatures are found.

• In addition it is formulated to provide excellent control of deposit and sludge formation, contributing to extended oil drain intervals, in comparison with mineral oil based refrigerator oils.

APPLICATIONS

REFRIGERATOR COMPRESSORS

• Shell Refrigeration Oil S4 FR-V is recommended for use in open, semi-open and hermetic compressors in domestic, commercial and industria lrefrigeration systems. It can be used in both rotary and reciprocating compressor types.

REFRIGERANT COMPATIBILITY

• Shell Refrigeration Oil S4 FR-V is designed for use with most commonly occurring refrigerants:

• Ammonia (R717) systems where it o‑ers excellent performance, even under high compressor discharge temperatures or down to evaporation temperatures of -33°C or lower.

• Carbon dioxide (R744) systems.
• CFC and HCFC systems (R12 and R22).
• Hydrocarbon systems such as propane (R290).
