Aircol SW 220(5L)
Aircol SW 220 is a synthetic refrigeration compressor lubricant formulated from polyol-ester (POE) base stocks.
Key Features & Benefits:
-
Fully miscible with HFC refrigerants (notably R134a), even at low temperatures.
-
Wax-free formulation giving a low pour point, which helps prevent pipe blockages and maintains clean evaporators for efficient heat transfer.
-
Good hydrolytic stability, load-carrying capacity, and protection against copper-plating — making it suitable for refrigeration compressors under load.
-
ISO viscosity grade 220 (≈ 220 mm²/s at 40 °C), giving relatively high viscosity when needed while maintaining flow at operating temperatures.
