LiquiCool® Coolant Distribution Units is the World’s Most Energy and Space Efficient Cooling Solutions for Reducing Data Center Costs.

The Coolant Distribution Unit (CDU) provides closely controlled cooling water for the Coolcentric Rear Door Heat Exchangers. The CDU creates an isolated secondary loop, separate from the chilled water supply (building chilled water, dedicated chiller etc.), enabling strict containment and control of the liquid cooling system. The CDU maintains the secondary loop supply temperature above the dew point of the data center, preventing condensation and ensuring 100% sensible cooling. Heat removed by connected Rear Door Heat Exchangers is then rejected to the chilled water supply by means of a stainless steel plate heat exchanger within the CDU. The CDU controller provides intelligent monitoring and interfaces with building management systems and web management tools for the highest reliability.

The floor-mount CDU is a versatile unit designed with redundant variable speed pumps, actuators and control valves to maximize system availability. This CDU provides up to 150kW capacity and supports up to 12 Rear Door Heat Exchangers. It is available with a variety of secondary loop distribution options offering maximum flexibility. Easy to deploy and maintain, the CDU can be placed next to IT enclosures or outside of the white space entirely.

Coolcentric rack-mount CDU is a 6U high unit that mounts within a 19" EIA IT enclosure. Rated at 20kW, this smaller CDU is a cost effective method to support 1-2 Rear Door Heat Exchangers.
