Energy-efficient dual-evaporator chillers

Medium of heat transfer (water) in direct contact with ice

Circulation of chilled water (non-hazardous and non-toxic)

Consistent leaving water-temperature of 1.1°C

Wider temperature differential (up to 10-11°C compared to 6.6°C for conventional chilled water system)

Requires lower flow-rate, thus lower energy consumption

Smaller system components (AHU, heat exchanger, pumps, distribution pipes etc) - more energy savings

Better control of humidity for better comfort
