Refrigeration Compressor Lubricantsmobil zerice s series

Product Description

Mobil Zerice S Oils are premium quality synthetic refrigeration compressor lubricants. Based on alkyl benzenes, which due to their nature, have superior miscibility with hydrochlorofluorocarbon (R22), as well as chlorofluorocarbon  refrigerants (R 502 and R 12: possibly used on some old refrigerating plants). This allows them to be used in very low temperature applications, down to -60C.

Features, Advantages and Benefits

Relative to mineral and other synthetic lubricants, Mobil Zerice S has superior solubility with halocarbon refrigerants. This helps avoid the common problem of oil separation and congealing on the valve and heat transfer surfaces of the refrigeration system.

Additionally, Mobil Zerice S lubricants have very low pour and floc points which helps prevent harmful wax precipitation that can block expansion valves and heat transfer surfaces.

Mobi Zerice S lubricant's synthetic nature provides excellent chemical stability and resists reaction with refrigerants and high thermal stability  which helps prevent oil breakdown.

FeaturesAdvantages and Potential Benefits
Miscibilty with halocarbon refrigerants Increased system efficiency
Low pour and floc points Avoids wax precipitation and increased system efficiency
Chemical Stability Long oil service life



Mobil Zerice S lubricants are recommended for all refrigeration compressor types, reciprocating or rotary screw types. They are well suited for use with fluorocarbon refrigerants.  They should not be used with sulfur dioxide or R134A refrigerants.  The specific viscosity grade should be selected in accordance with the compressor manufacturer's recommendations.
