Coolcentric Coolant Distribution Units
The Coolant Distribution Unit (CDU) provides close controlled cooling water for a variety of heat exchanger devices such as the Coolcentric Rear Door Heat Exchangers (RDHx). Creatation of an isolated secondary loop, separate from the chilled water supply (building chilled water, dedicated chiller etc.), enabling strict containment and precise control of the liquid cooling system. This 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 RDHx is then transferred to the chilled water supply by means of a stainless steel plate heat exchanger. The Coolant Distribution Unit (CDU) controller provides intelligent monitoring and interfaces with building management systems and web management tools for the highest reliability.
The CDU Model CD6C is a floor mount. It is a versatile unit designed with redundant variable speed pumps to maximize system availability. This unit provides up to 305kW cooling capacity to support up to 26 rear door heat exchangers each with a 10kW load density. The CDU Model CD6C is very energy efficient providing up 260kW of cooling while only consuming a maximum of 3.7kW of energy at 480VAC. This represents nearly 80% reduction in energy consumption when compared to traditional indoor air conditioning units.
The small footprint (600mmx1000mm) and casters makes it easy to deploy and maintain either floor mount model whether it is positioned next to IT enclosures or outside of the white space entirely. Both models are available with a variety of secondary loop distribution options offering maximum flexibility.
Coolcentric’s rack-mount Coolant Distribution Unit Model CDRM is a 5U high unit that mounts within a 19” EIA IT enclosure. Rated at 50kW, the CDU Model CDRM is a cost effective method to support one to two RDHx in a data center or wiring closet.
