HPC Seetul S 68 are fully synthetic lubricants, designed for use in refrigeration compressors and heat pumps. They are formulated from polyalphaolefin (PAO) fluids, which have outstanding resistance to thermal/oxidative degradation. Their natural high shear stable viscosity index and low temperature fluidity, make them perform in severe service conditions that are beyond the capabilities of conventional mineral oils.

Their solubility and miscibility with refrigerants is low, resulting in higher film thickness in the presence of refrigerants under pressure and reduced shaft seal leakage. Their stability and low volatility eliminates "light end stripping" which can occur with conventional mineral oils.

They are specifically recommended for the lubrication of refrigeration compressors operating at very high temperatures, and for systems with very low evaporator temperatures. They are suitable for compressor systems using refrigerants such as ammonia, carbon dioxide and HCFCs such as R-22; and CFC R-12. They are compatible with all refrigerants except sulphur dioxide. They are not compatible with Mineral oils.

SEETUL SE 68 is a special tailor made synthetic product to suit air conditioning system and refrigeration compressors. This product is available in 20 Ltr packaging.

SEETUL GRADES ARE RECOMMENDED FOR WIDE RANGE OF REFRIGERATION COMPRESSORS, BOTH RECIPROCATING AS WELL AS ROTARY, USING ALL CONVENTIONAL REFRIGERANTS EXCEPT SULPHUR DIOXIDE.
