Specification of Shell Refrig S2 FR-A 68 . Compressor Oil
Shell Refrig S2 Compressor Oil FR-A 68 is a low solubility compressor lubricant intended for use in refrigeration compressors using Ammonia refrigerant. It is formulated from specially refined paraffinic base oils in combination with selected additives to minimize system deposits and provide a long service life.
Superiority:
System efficiency. Shell Refrigeration Oil S2 FR-A has been specifically optimized for use in systems where oil separation is required. It has been designed to reduce “light end” oil residue; this minimizes oil thickening in the compressor and reduces the internal evaporator surface oil film thereby maintaining overall system efficiency.
Extended treatment intervals. Shell Refrigeration Oil S2 FR-A has excellent high temperature and oxidation stability providing a long service life even when high compressor discharge temperatures are encountered. It is also formulated to provide excellent control of deposition and sludge formation resulting in longer oil drying intervals compared to conventional mineral oil based cooling oils.
