1MW Coolant Distribution Unit (CDU)

Facing the heat dissipation challenges of ultra-large-scale AI computing clusters and high-density data centers, traditional cooling solutions can no longer meet the demands of kilowatt-level computing loads. The WONE 1 MW CDU is a high-power coolant distribution unit purpose-built for large liquid-cooled data centers. With ultra-high heat exchange efficiency, fully redundant safety design, and intelligent management capabilities, it provides stable and reliable liquid cooling support for megawatt-level computing loads, ensuring efficient, energy-saving, and safe data center operation.

Core Product Positioning

The WONE 1 MW CDU is a high-power coolant distribution unit designed for large liquid-cooled data centers. Its core function is to provide efficient coolant distribution, heat exchange, and temperature control management for high-density, large-scale computing clusters. With a rated heat exchange capacity of 1000 kW and an integrated rack-mount design incorporating heat exchange, circulation, filtration, monitoring, and safety protection, it reliably supports centralized liquid cooling for supercomputing centers, AI computing centers, and large data centers — delivering a complete, highly reliable liquid cooling solution.

Core Product Features

• 1 MW ultra-high heat exchange capacity for high-density loads: Rated heat exchange capacity of 1000 kW, secondary side rated flow of 1800 LPM, easily supporting ultra-large-scale GPU/CPU clusters. Flow adjustment range: 40–100%, allowing dynamic adjustment based on load for both efficient cooling and energy savings.

• Fully redundant design for uninterrupted operation: 1+1 redundant pump configuration with automatic failover; dual power supply with ATS automatic transfer switch for seamless power backup when the main supply fails. Multi-level redundancy ensures 7×24 uninterrupted operation.

• Multi-layer safety protection for worry-free operation: Built-in leak detection and liquid quality monitoring continuously track system status and provide early warnings. Bypass filter supports online replacement without shutdown — filtration accuracy 50 μm. Automatic coolant refill monitors liquid level and replenishes as needed.

• Intelligent precision temperature control for complex conditions: PID control dynamically adjusts based on supply/return temperature sensor data for accurate temperature management. Primary and secondary side temperatures support 35°C/45°C and 40°C/50°C wide-range operating conditions. Supports Modbus RTU & TCP/IP for seamless integration with facility monitoring systems.

• Wide environmental adaptability for flexible deployment: Operating ambient temperature −10 to 55°C, storage temperature −45 to 70°C, adaptable to diverse geographic locations and server room environments. IP55 ingress protection for dust and water resistance. Equipped with a 10.1-inch touchscreen display for visual HMI.

• Low power design for energy savings: Total power consumption <18 kW, delivering ultra-high heat exchange efficiency while minimizing self-consumption, helping data centers reduce PUE.
