175 to 550 Nominal Tons (615 to 1,934 kW)
The 23XRV chiller is the world’s first integrated variable-speed, water cooled, screw chiller. The 23XRV incorporates significant breakthroughs in water-cooled chiller technology to provide excellent reliability and achieve superior efficiency at true operating conditions without compromising the environment. Quality design and construction make the AquaEdge® 23XRV chillers the best choice for modern, efficient chilled water plants.
Carrier's AquaEdge® chillers offer the best value in high-efficiency chlorine-free variable-speed screw 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.
