Centrifugal Chiller achieved high efficiency through Two-stage Compressor. With optimized Two-stage compressing cycle, energy efficiency has been improved and operation costs has been reduced as opposed to the previous One-stage Centrifugal Chiller.

A centrifugal chiller utilizes the vapor compression cycle to chill water and reject the heat collected from the chilled water plus the heat from the compressor to a second water loop cooled by a cooling tower.
