The AquaEdge® 19XR/XRV centrifugal chillers achieve energy efficiency levels using proven technology designed specifically for chlorine-free refrigerant. This combination ensures the most cost-effective, reliable solution for today's comfort cooling and process cooling applications.

Carrier's AquaEdge® chillers offer the best value in high-efficiency, chlorine-free centrifugal HVAC chillers.

Water-cooled chillers within the scope of the AHRI WCCL certification program are certified in accordance with the AHRI Water-Cooled Water-Chilling and Heat Pump Water-Heating Packages Certification Program, which is based on AHRI Standard 550/590 (I-P) and AHRI Standard 551/591 (SI). Certified units may be found in the AHRI Directory at www.ahridirectory.org.
