Technical Specifications

CDU solution providers often release theoretical performance data when a new product is launched. nVent can provide RackChiller CDU800 data based on actual performance through independent lab verifications and results from early platform users. These experimental data provided information on the high performance of the RackChiller CDU800, heat exchange, flow and pressure.

The RackChiller CDU800 delivers 800 kW liquid cooling capacity at 4K approach temperature and delivers high performance liquid flow, pressure delivery and heat dissipation within the footprint of a standard IT rack. CDU is an ideal high-density coolant dispensing solution for convergent and direct-to-chip cooling applications.

The RackChiller CDU800 is designed for reliability, availability, and serviceability. The platform is designed with N+N redundant pumps providing up to 950 liters per minute of secondary flow and 46 pounds per square inch (3.2 bar) of differential pressure.

The CDU includes an intelligent control system that continuously monitors over 35 integrated sensors. This combination, along with a lower approach temperature throughout the operating range, can eliminate the need for costly coolant support by enabling ASHRAE Class of Engineers W45 warm water liquid cooling for high-power IT systems. The pumps, sensors and filtration system can be operated without incurring downtime or affecting performance during operation.

The complete system is integrated into an aesthetic enclosure with a 10-inch color touch screen, side panels and removable doors. CDU can be installed on a slab or raised floor, respectively with IT equipment racks, or a separate facility room.

Through its nVent HOFFMAN, nVent RAYCHEM and nVent SCHROFF brands, nVent offers the most complete and innovative thermal management solutions for a variety of applications to meet equipment protection needs. From standard fan kits to air conditioners, heat exchangers, liquid cooling, leak detection and more, customers can choose from over 2,000 UL®-listed and recognized products for reliable operation and longer life for protected components.
