Coolant Distribution Unit (CDU)
Cooling Distribution Units (CDUs) are essential components in liquid cooling systems. They distribute coolant or water evenly throughout the system while regulating temperature and flow rate.
Liquid-to-Liquid CDU
Our company offers the DHS-X430175-01 coolant distribution unit, a 4U height, and 19-inch rack-mounted appliance designed to distribute coolant through the cold plate loop. This effectively removes heat load from IT components within a rack.
The CDU product features a plate-type heat exchanger for liquid-to-liquid heat exchange. It transfers heat from the secondary liquid side to the primary liquid coolant, effectively transporting heat from IT components on the secondary side to the facility chiller on the primary side.

| - ASHRAE W4 warm water cooling without the need for chillers. - Easy setup for a liquid cooling solution. - Provides 100 kW of cooling capacity at an approach temperature of 25°C. - Redundant pump design with a 2 + 1 pump arrangement, featuring two active pumps and one redundant pump. - Equipped with a leakage alarm and protection system. - Designed for rack mounting. - Offers multiple control mechanisms, including fixed secondary supply flow rate, fixed secondary supply pressure, and secondary supply temperature settings |
- Operation and Storage Conditions: - Operating ambient temperature: 5 to 45°C - Secondary supply temperature: 0 to 65°C - Maximum secondary operating pressure: 190 kPa - Storage temperature range: -20 to 60°C |
Liquid-to-Air CDU
The Delta Coolant Distribution Unit, with the model number FHS-X440350-01, is a rack-mounted appliance measuring 8RU in height and designed to fit into a 19-inch rack. Its primary function is to distribute coolant through manifolds and a cold plate loop, effectively removing heat generated by IT components within a rack.
One of the key features of the FHS series CDU product is its liquid-to-air heat exchanger, which efficiently transfers heat from the liquid coolant to the surrounding air.
