Danfoss, Baltimore, Md., introduced an option to use R-513A refrigerant on low-GWP (global warming potential) compressors.

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.

Danfoss also expanded the operating range of its Turbocor TT Series compressors to support low lift applications such as air-cooled heat pumps. The low lift operating range allows chillers to start and operate at low condenser water temperatures common during cold ambient temperature conditions.
