4+3kW Low-Noise C&I BESS Liquid Cooling Chiller – PACK & PCS Dual Circuit

CTHB-D1HW040030FB34-220-2-2 is a low-noise liquid cooling chiller for commercial and industrial battery energy storage systems. Two coolant circuits serve the battery PACK and PCS: 4kW battery-side cooling and 3kW PCS-side cooling at their separately specified inlet-water temperatures. At 50°C ambient and 50% relative humidity, battery-side cooling is rated with 18°C inlet water and PCS-side cooling with 55°C inlet water. The dual-circuit arrangement is for different thermal duties, not full-duty standby redundancy.
