Carrier, the United States, has become the latest chiller company to design a machine using low global warming potential (GWP) refrigerant R1233zd(E). The new AquaEdge 19DV two-stage, variable-speed centrifugal chiller is featured on the Carrier. Produced by Honeywell as Solstice zd, R1233zd(E) is a single component, non-flammable A1, fourth generation HFO refrigerant. It was originally developed for use as a blowing agent but has also been found to be a high efficiency alternative to R123.
