WINNER – Green Building

Carrier’s Evergreen® 23XRV chiller is the world’s first integrated variable speed, water-cooled, screw chiller.

It incorporates significant break- throughs in water-cooled chiller tech- nology to provide excellent reliability and achieve superior efficiencies at true operating conditions without com- promising the environment.

The 23XRV chiller provides:

•Variable speed, positive displacement screw compressor.

•Air Conditioning, Heating, and Refrigerant Institute (AHRI) certified efficiencies to 0.33 kW/ton (AHRI IPLV).

•Chlorine-free HFC-134a refrigerant.

•IEEE-519 compliance for harmonic distortion.

•An ideal solution for constant and variable flow pumping systems.

Features/Benefits

Quality design and con- struction make the Evergreen 23XRV chillers the best choice for modern, efficient chilled water plants.

Product reliability

The 23XRV chiller uses proven tech- nology from Carrier’s existing line of Evergreen chillers along with innova- tions that increase reliability. The 23XRV compressors are designed for extremely high reliability. The ad- vanced tri-rotor compressor features a balanced rotor geometry and shorter screw lengths, resulting in vastly re- duced compressor bearing loads and a minimum L10 compressor bearing life in excess of 500,000 hours when op- erated at AHRI conditions.
