In-rack 150 kW liquid-to-liquid CDU
150 kW of heat exchange in 6U. A high-efficiency plate exchanger, dual pumps and variable-frequency circulation, sized for high-density AI racks.
Built around the heat load, not around a rack size.
This in-rack CDU is tailored for cold plate liquid cooling systems. Its compact design fits standard 19-inch racks without occupying additional floor space. Dual-pump redundancy and variable-frequency circulation hold precise temperature control while significantly reducing the data center PUE.
Heat exchange, fluid replenishment and monitoring are integrated into a single unit, so it can be deployed independently. Built-in multi-level protection against leaks and over-temperature, together with visualised smart O&M, make it suitable for edge computing and for retrofitting small-to-medium AI computing rooms.
