Coolant Distribution Unit (CDU)

Rackmount Liquid-Liquid CDU

The secondary side heat exchange unit CDU is mainly used for heat exchange control of liquid cooling heat sink systems. The system integrates the secondary side frequency conversion circulating pump, plate heat exchanger, electric control valve, temperature sensor, pressure sensor, filter, pressure stabilizing tank, etc. The system is pre-installed and debugged at the factory, which reduces the on-site workload.
