Synthetic Refrigeration Compressor Lubricant (SRNC5)
Podlee Polyol Ester (POE) synthetic refrigeration oil is a high-performance lubricant specifically engineered for modern refrigeration and air-conditioning systems, particularly those using hydrofluorocarbon (HFC) refrigerants (e.g., R-134a, R-410A, R-404A). As a key member of synthetic refrigeration oils, POE oils are renowned for their exceptional compatibility with environmentally friendly refrigerants and their ability to meet stringent operational demands.
Application
Commercial/Residential HVAC-R Systems: Compatible with HFC-based chillers, heat pumps, and air conditioners.
Automotive Air Conditioning: Used in electric vehicle (EV) thermal management systems and traditional automotive AC units.
Industrial Refrigeration: Cold storage, food processing, and pharmaceutical chillers.
CO2 (R-744) Transcritical Systems: Some POE blends are tailored for CO₂ applications.
Advantages
Environmental Compliance: Replaces CFC/HCFC-compatible mineral oils in HFC systems, supporting global phase-out of ozone-depleting refrigerants.
Extended Service Life: Reduces oil change frequency due to superior stability.
Energy Efficiency: Low friction improves compressor efficiency, lowering energy consumption.
