VISCOSITY - ISO 100

Synthetic refrigeration compressor lubricant.

DESCRIPTION

The Castrol Aircol SW range of synthetic refrigeration lubricants are formulated from polyolester base stocks.

APPLICATIONS

They are specifically designed for use with refrigeration systems using environmentally friendly HFC refrigerants, in particular R134a.

ADVANTAGES

The synthetic base stocks used in the Aircol SW range are fully miscible with HFCs, in particular R134a, even at temperatures well below the minimum likely to be encountered in service.
The Aircol SW grades have been formulated to enhance hydrolytic stability, load carrying and inhibition against copper plating. They are wax free and hence have very low pour points. This ensures the evaporator remains clean (consequent efficient heat transfer) and reduces the risk of pipe blockages.
