2nd Generation - 6H.2(Y)
With the 2nd generation, BITZER has taken a decisive step forward: There is now a model range for chlorine-free HFC refrigerants and HFCKW. Thanks to their highly efficient and robust designs, the standard compressors meet all the criteria for operation with chlorinated and chlorine-free refrigerants.
- Suitable for coupling and belt drives.
- Pressure oil lubrication with reversible gear pump.
- The special oil return system results in extremely low oil carry over.
