2nd Generation - 2T.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.
