AquaEdge® Water-Cooled Centrifugal Chiller

The AquaEdge 19MV Water-Cooled Centrifugal Chiller – Experience Unconditional Performance. It’s time to rethink what you know about chillers. In the past, more operating range often meant less efficiency at design conditions. Now Carrier has created a chiller that delivers both, unconditionally. The all-new AquaEdge 19MV chiller can provide MORe :   More O perating Range and high efficiency at design conditions.

Quickly evaluate chiller system performance

Carrier’s PLV Pro is a software tool that empowers consulting engineers to make objective and informed decisions about their chiller plant design that go beyond Full Load and IPLV metrics. Results are provided in a professional report or .csv format for further analysis. The tool is for professionals who need a quick and free-of-charge alternative to detailed energy modeling analyses.  

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
