Description
The Castrol Aircol SW 32 is a synthetic refrigeration compressor lubricant (ISO VG 32) formulated from Polyolester (POE) base stocks. It is specifically designed for use with refrigeration systems using environmentally friendly HFC refrigerants, in particular **R134a**.
- Pack size: 5 L canister
- Also available in: 20 L canister
Applications
- Refrigeration compressors and cooling systems that use HFC refrigerants.
- Particularly suitable for systems operating with **R134a** refrigerant.
Benefits
- High Miscibility: Fully miscible with HFCs (in particular R134a) even at temperatures well below the minimum encountered in service.
- Efficient Operation: Wax free with a very low pour point (-46°C), ensuring a clean evaporator and efficient heat transfer.
- Stability: Enhanced hydrolytic stability and inhibition against copper plating.
- Load Carrying: Good load carrying capacity for the protection of compressor components.
