Ammonia (NH₃) Immiscible Refrigerant Compressor Oil (DRA)
Application areas:
Designed specifically for ammonia-based (NH₃) refrigeration systems, where the lubricant must remain immiscible with the refrigerant.
Ideal For:
-Industrial refrigeration units
-Cold storage facilities
-Food & dairy processing plants
-Meat & poultry chilling systems
-Ice factories
-Ammonia-based commercial refrigeration systems
-Low-temperature ammonia compressors
Equipment Types:
-Reciprocating refrigeration compressors
-Screw type ammonia compressors
-Industrial chillers
-Freezer compressors operating at very low temperatures
Perfomance benefits:
-Excellent chemical stability with ammonia refrigerant
-Immiscible formulation ensures proper oil return and separation
-Prevents sludge, varnish, and deposit formation in low-temperature circuits
-Superior lubricity reduces wear on pistons, bearings, and valves
-High thermal stability for continuous refrigeration operation
-Prevents moisture-related corrosion inside ammonia compressors
-Enhances compressor efficiency and reduces energy losses
Special Features:
-Formulated with high-quality Group II base oils
-Special ammonia-compatible additive package (0.4–4%)
-Excellent low-temperature flow characteristics
-Strong resistance to ammonia-induced oil breakdown
-Highly refined, low-wax composition ensures smooth operation
-Designed for long fluid life in ammonia cooling plants
