Yes. The CHx2000 is a liquid-to-liquid CDU and connects to the facility water system through a 4″ tri-clamp interface. If your data center does not have facility water available, CoolIT’s AHx240 and AHx180 are self-contained liquid-to-air CDUs that reject heat directly to the room air.

One CHx2000 provides 2,000 kW of cooling, enough for up to 12 NVIDIA GB300 NVL72 racks. For larger clusters, multiple CHx2000 units can be group-controlled through a single Redfish interface. Up to 20 CDUs in one group support 240+ GB300 NVL72 racks under unified operator visibility.

Yes. Warm-water cooling is supported across CoolIT’s CDU portfolio, enabling free-cooling operation in most climates and heat-reuse strategies where facility infrastructure supports it. That reduces reliance on mechanical chillers and improves overall data center PUE. Learn more in our article on warm-water cooling and AI.

The CHx2000 integrates with data center management systems through Redfish, and supports group control across up to 20 CDUs from a single interface. That coordinates pump, flow, temperature, and alert states at cluster scale.

The CHx2000 is designed for continuous operation in mission-critical AI infrastructure. Pumps and TCS filters are front and rear accessible for fast field service without stopping the loop, and every unit is validated against a 6 MW simulated load before shipping from CoolIT’s Canadian manufacturing facility.
