Mobil’s Gargoyle Arctic SHC 228 is an entirely synthetic, superlative performance lubricant. This oil was specially formulated to use with refrigeration compressors as well as heat pumps. The formula is free from wax, and has a fluid form of hydrocarbon polyalphaolefin (PAO) added. This give the product a high level of resistance to oxidative or thermal degradation.
The intrinsically high index of shear stable viscosity, combined with cooler temperature fluidity, means this lubricant can perform, even in severe conditions that are too much of a challenge for standard mineral-based oils.
The miscibility and solubility is low when used with refrigerants, the result of which is a higher level of film thickness – even when under intense pressure. This can make for less shaft seal leaks. The reduced volatility and increased stability prevents the ‘light end stripping’ that can happen when conventional mineral oil is used.
Mobil Gargoyle Arctic SHC 228 can assist in the reduction of frictional loss and increase the efficiency of machine operation. This lubricant is highly suited to high temperature refrigeration compressors, as well as low temperature evaporator systems.
The oil is compatible with compressors that use ammonia, carbon dioxide, R-12 or other CFC refrigerants – but not sulphur dioxide.
Gargoyle Arctic SHC 228 can be used in combination with mineral-based products, but this could detract from this lubricant’s superior performance.
