The DCX Enterprise Coolant Distribution Unit (ECDU) is an advanced rack-based coolant distribution platform engineered for high-density, mission-critical environments where performance, reliability, and scalability are essential. It represents a significant technological advancement over conventional CDUs, combining ultra-low approach temperature, exceptionally high flow rates, and full system redundancy within a standard in-row footprint. Designed for modern data centers, including enterprise, colocation, cloud, and hyperscale deployments, the ECDU platform supports supply water temperatures up to 45°C while maintaining class-leading AT3 energy efficiency. Its optimized hydraulic architecture, high-capacity pumping system, and integrated coolant management ensure stable and consistent thermal performance even under extreme heat loads. With a scalable portfolio ranging from 600 kW to 2.6 MW of real cooling capacity, the DCX ECDU enables operators to precisely align performance, redundancy, and investment with specific deployment requirements.
