BITZER polyolester oils significantly exceed the requirements of DIN 51503, Part 1, for refrigeration compressor oils with respect to water content and total acid number (TAN). They mix well with HFC and HFO refrigerants and are therefore especially suitable for operation with these substances
Retrofit of R22 to HFC blends: due to their high polarity, polyol ester oils (POE) must be used. Sufficient miscibility/solubility is not guaranteed when MO (mineral oil) and/or AB (alkylbenzene) lubricants are used!
