Welcome to a new version of the BITZER Software!

What is new in 6.17.5?

R1234ze(E) performance data for CSW105 compressors
Implementation of performance data for CSW105 compressors with the refrigerant R1234ze(E) for condensing temperatures up to 65°C for a maximum evaporating temperature of 25°C. Depending on the point of operation, BSE170 has to be used as oil.

New VARIPACK frequency inverters
The new VARIPACK frequency inverters FMU+6-4 ... FQU+202-4 have been added to the BITZER software. The enclosure class is IP20.

Performance data for ORBIT Boreal compressors with R454B
For ORBIT Boreal compressors, individual 50 Hz performance data can now be calculated with the refrigerant R454B.
