23XRV AquaEdge

Variable Speed Screw Chiller

175 to 550 Nominal Tons (615 to 1934 kW)
23XRV Icon

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 efficiencies 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.
