Refrigerator Compressors - Shell Refrigeration Oil S2 FR-A 68 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. Refrigerant Compatibility - Shell Refrigeration Oil S2 FR-A 68 is recommended for use with ammonia (R717) based refrigeration systems where it offers excellent performance, even under high compressor discharge temperatures, or down to evaporation temperatures of -30 C. It can also be used in systems using hydrocarbons such as propane (R290). Shell Refrigeration Oil S2 FR-A 68 is NOT recommended for use with CFC, HCFC, or HFC refrigerants such as R12, R22 or R134a. |

System Efficiency - Shell Refrigeration Oil S2 FR-A 68 has been specially optimized for use in systems where oil separation is required. It has been designed to reduce "light end" oil carryover; this minimizes oil thickening in the compressor and reduces oil coating of internal evaporator surfaces thus maintaining overall system efficiency. Extended Maintenance Intervals - Shell Refrigeration Oil S2 FR-A 68 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 conventional mineral oil based refrigerator oils. |
