PVE or polyvinyl ether lubricants are finding increased application and use by compressor and equipment manufacturers. The list of OEM's that have tested and approved Idemitsu's PVE Lubricants is impressive. PVE lubricants exhibit excellent performance characteristics in air conditioning and refrigeration applications, and they are particularly well suited for use with HFC refrigerants such as R-134a, R-404, R-407C, and R-410A. In fact, PVE lubricants are compatible with all HFC refrigerants.
