Industrial and commercial compressor maker Bitzer released a new version of its selection software. The software, version 6.4.3, can be downloaded from the company's website or at

According to the company, the new version matches the company’s compressors with the latest generation of refrigerants, including the Ecoline series with R448A, R449A, R450A and R513A, and semi-hermetic screw compressors with R448A and R449A.

With global warming potential around 65 percent lower, R448A and R449A are a suitable alternative for R404A. Ecoline compressors do not require cooling through liquid injection even in low temperature applications. All the refrigerants are allocated to the safety group A1 and declared as noncombustible.
