The air-cooled modular chiller is a central air conditioning unit that uses air as its cooling and heating source and water as the heat transfer medium. The unit can form a centralized air conditioning system together with FCU and AHU for cooling in summer and heating in winter. King series air-cooled units employ a modular design, and include 35 kW and 130 kW modules. Up to 16 modules can be connected in parallel to form a combination product from 35 kW to 2,080 kW.
