Performance, Features & Benefits

- 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 resulting in extended oil drain intervals in comparison with mineral oil based refrigerator oils.

Main Applications
- Refrigerator compressors
Shell Refrigeration Oil S4 FR-V is recommended for use in open, semi-open and hermetic compressors in domestic, commercial and industrial refrigeration systems. It can be used in both rotary and reciprocating compressor types.  Because of its solvency power and compatibility with mineral oils it can be used as a flushing fluid in
turbine circuits.  For more information contact your local Shell representative.
