Key Features & Benefits
-
System Efficiency
- Reduces ''light-end'' oil carryover, preventing oil thickening and minimizing evaporator surface coating.
- Ensures consistent performance and optimized energy efficiency.
-
Extended Maintenance Intervals
- Excellent high-temperature and oxidation stability.
- Minimizes deposit and sludge formation, extending oil drain intervals compared to conventional mineral oils.
-
Broad Temperature Range
- Performs reliably under high compressor discharge temperatures or down to evaporation temperatures of -30°C.
-
Refrigerant Compatibility
- Fully compatible with ammonia (R717) and hydrocarbon refrigerants like propane (R290).
- Not suitable for CFC, HCFC, or HFC refrigerants such as R12, R22, or R134a.
Main Applications
-
Refrigerator Compressors:
Suitable for open, semi-open, and hermetic compressors in domestic, commercial, and industrial systems. -
Rotary and Reciprocating Compressors:
Engineered for use in both types of compressors.
