Carrier-Aquaedge

CHINA: US manufacturer Carrier has become the latest chiller company to design a machine using low GWP refrigerant R1233zd(E).


The new AquaEdge 19DV two-stage, variable-speed centrifugal chiller is featured on the Carrier China stand at this week’s China Refrigeration Expo in Beijing. It features Carrier’s Greenspeed variable frequency drive motor controller and is said to achieve market-leading refrigeration efficiencies.

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.

US rival Trane was the first to adopt the refrigerant when it launched its Series E CenTraVac water-cooled centrifugal chiller in 2014. It was followed last year by Mitsubishi Heavy Industries’ launch of the ETI-Z Series using the same refrigerant.
