Compact Power. Maximum Efficiency

100 kW Liquid-to-Liquid In-Rack CDU

Overview The Cooler Master 4U 100 kW CDU effectively manages a high server-rack heat load, dissipating 100 kW of heat from ever-increasingly high-density data center applications that require an in-rack solution. This enables high-capacity liquid cooling for data centers, providing significantly higher power and compute density. The CDU effectively segregates facility water in the primary loop and efficiently exchanges heat from the IT cooling loop via a high-efficiency plate heat exchanger, achieving an approach temperature difference of 13°C with 100 kW of heat dissipation.
