BITZER compressors which are intended for use with chlorine-free HFC and HFO refrigerants (R134a, R404A, R407A/C/F, R507A, R1234yf, R513A, R450A etc.) are charged with a high-quality polyolester oil. In these cases, a “Y” is added to the type designation of the compressor. 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.
BITZER compact screw compressors for R22 are charged with a high-quality complex ester oil. It significantly exceeds the requirements of DIN 51503, Part 1, for refrigeration compressor oils with respect to water content and total acid number (TAN). It mixes well with R22 and is therefore especially suitable for operation with this substance.
