What is Solest?

Solest is Lubrizol Fluid Engineering’s dedicated range of polyol ester (POE) refrigeration lubricants. The line has been formulated for specific use in air conditioning and refrigeration compressor systems that function using HFC (hydrofluorocarbon) refrigerants.

However, when operating under set conditions, Solest lubricants are also an outstanding solution for use in other systems where HFO (Hydrofluoroolefin) and HFCF (hydrochlorofluorocarbon) refrigerants are used.
