Danfoss expanded its portfolio of compressors with low global warming potential (GWP) by introducing an option to use R-513A. The company also added to its operating map range to cover low lift applications for the TT Series compressor family.

R-513A is a low-GWP, non-flammable (A1) alternative refrigerant to R-134a that allows chiller manufacturers to meet future HFC regulations such as the European Union’s F-gas regulation.  All Turbocor TT Series compressors produced starting in December 2017 with compressor firmware version 4.1 will be compatible with both R-134a and R-513A.

Turbocor TT Series compressors’ expanded operating range can now support low lift applications such as low temperature process cooling, air-cooled heat pumps and ice storage. The low lift operating range allows chillers to start and operate at low condenser water temperatures that are common during cold ambient temperature conditions. This allows manufacturers to avoid using economizers on chillers.
