It is a system that supplies high temperature water up to 80℃ by using 70-80% of unused energy such as waste heat source, river water and ground water discharged from power plants and sewage treatment plants. It can save energy economically because it draws low temperature heat energy to high temperature heat energy with small amount of energy.

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.
