R-513A. Carrier, a world leader in high-technology heating, air-conditioning and refrigeration solutions, is a part of UTC Climate, Controls & Security, a unit of United Technologies Corp. 

“Our customers rely on Carrier for quality, reliability and predictability and they will be pleased to know our AquaEdge 19XR and 23XR water-cooled chillers along with our AquaForce 30XV/XA air-cooled chillers are able to transition smoothly from R-134a to lower GWP R-513A at the same time we pursue the development of other low global warming refrigerant alternatives,” said Chris Opie, director, North America Commercial Marketing. “We believe R-134a will continue to provide the best combination of availability, cost, performance and safety for many years to come. The ability to convert our R-134a centrifugal chillers to lower GWP R-513A provides owners and facility managers even greater options that ensure the full useful life of this chiller."
