Aircol CM Range
The Castrol Aircol™ CM compressor oil range of high-quality lubricants are based upon highly refined mineral oil, enhanced with additive technology providing excellent thermal and oxidative stability and good load carrying capacity, compared to other products in the same class. Aircol CM grades are formulated without zinc additives (ashless oils), recommended for the lubrication of rotary screw and reciprocating compressors.
Aircol LPT Range
Castrol Aircol™ LPT is a refrigeration compressor lubricant formulated from highly refined naphthenic base oils for use in both large and industrial and small refrigeration units. Aircol LPT is formulated to function as a lubricant and coolant, as well as a sealant in refrigerating compressors. It maintains good lubrication properties at the high temperatures reached during the compression phase and good fluidity at the low temperatures within the evaporators. Excellent lubrication of the moving parts in the compressor.
Aircol SN Range
Aircol SN were developed to cope with the severe operating conditions experienced in reciprocating air compressors operating at high compression ratios and high discharge temperatures of up to 220°C. Under these conditions, Aircol offer a much reduced carbon forming tendency and extended oil life when compared to mineral oil. Whilst Aircol SN was primarily intended for the use in reciprocating air compressors, it may also be used in certain types of turbochargers, where it will provide significant in-service benefits when compared with mineral based lubricants.
Aircol SR Range
Castrol Aircol™ SR compressor oil range of premium lubricants are designed for use in rotary screw compressors and are based on polyalphaolefin (PAO) fluids. Aircol SR is suitable for use in oil flooded rotary screw compressors operating under extreme climatic conditions, harsh environments and severe operating conditions where very high air discharge temperatures (> 100°C) are experienced. These oils are also suitable for use in compressor units operating at normal operating conditions, with the maximum air discharge temperature =/< 100°C.
Aircol SW Range
Castrol Aircol™ SW range of synthetic refrigeration lubricants are formulated from polyolester base stocks. The range are specifically designed for use with refrigeration systems using environmentally friendly HFC refrigerants, in particular R134a.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[...]
