Bitzer Compressor Oil BSE 170

Oils for HFC and HFO refrigerantsBITZER 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 requirementsof 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 thesesubstances.Characterising the oilsOil Oil type Applications Designation on compressorBSE170 polyolester oil(POE)standard oil charge for e.g. CSH.5, CSVHoption for e.g. CSH.6, CSW"Y" (e.g. CSH8593‑140Y)BSE170L polyolester oil(POE)standard oil charge for e.g. CSH.6, CSW, CSVW "Y" (e.g. CSVW37-240Y)BSE55 polyolester oil(POE)standard oil charge for e.g. CSW with motor 4 "Y" (e.g. CSW8573-80Y)Tab. 1: BITZER oils for HFC and HFO refrigerants and their blends in compact screw compressorsThe approved refrigerants can be found in the respective operating instructions or the BITZER SOFTWARE.
