Overall

The CDU serves as the critical interface between the facility water system and the IT-side cooling circuit, providing hydraulic isolation and efficient heat transfer through an integrated heat exchanger.

It enables independent regulation of coolant temperature, flow rate, pressure, and differential pressure, while integrating key functions such as circulation, filtration, air removal, expansion, and system monitoring.

The CDU can interface with BMS, DCIM, SNMP, Modbus, and other control systems, and can be configured with N, N+1, or 2N redundancy to meet different requirements for system availability and reliability.
