ENVIRONMENTALLY FRIENDLY TECHNOLOGY

Hot water-fired absorption chillers

Chilled water of 8° C can be produced using waste hot water of 80° C to 95° C from gas engine etc. It is a chiller driven by waste hot water which temperature is low. Waste hot water and unused energy can be effectively used and it is suitable for combined heat and power system.
