Unfold the Power of Water

2,500 kW Liquid-to-Liquid In-Row CDU

The Cooler Master 2,500 kW Liquid-to-Liquid In-Row Coolant Distribution Unit (CDU) manages a 2,500-kW heat load. The CDU effectively segregates the primary and secondary loops using one brazed plate heat exchanger (BPHE). This enables high-capacity liquid cooling in data centers, providing significantly higher power and compute density. The high-efficiency heat exchanger can produce an approach temperature difference (ATD) of 5 degrees Celsius with 2,500 kW heat dissipation.

Features


  • Efficiently cools up to 2,500 kW.
  • Supports facility water supply temperatures from 2°C to 45°C (ASHRAE W2–W4 Liquid Cooling Class).
  • Maximum secondary flow rate: 4,200 LPM.
  • 46U in-row chassis.
  • Stainless-steel, gasket-less, brazed heat exchanger rated to 19 bars.
  • Sanitary flanges and clamps for easy connections.
  • Redfish API for remote management and monitoring.
  • Optional Multi-Machine Linkage for centralized coordination of multiple units.
  • 10.1-inch touchscreen with real-time monitoring.
  • Menu-driven interface for status, diagnostics, and configuration.
  • Monitors water quality with pH, ORP, conductivity, turbidity, and humidity sensors.

Benefits


  • Supports high heat loads with low power consumption (approximately 40 kW).
  • Offers standardized remote access and control.
  • Features a large, intuitive interface for easy operation.
  • Manages condensation by diverting low-temperature primary supply fluid to the return.
  • Keeps facility and IT equipment water separate, allowing different fluids in the secondary loop for specific needs.
  • Provides comprehensive secondary loop control and monitoring for optimal IT cooling.
  • Centralized management enables automatic failover and coordinated operation across units, improving energy efficiency and reliability while reducing complexity.
  • Delivers real-time alarm monitoring for complete system and environmental protection.
  • Enables early leak detection to prevent damage and flooding.
  • Streamlined menu system minimizes training time and simplifies maintenance.

MAXIMIZED COOLING WITH PRECISION

The Cooler Master 2,500 kW CDU is equipped with sensors to monitor various fluid conditions, including flow, pressure, pH, ORP, electrical conductivity, temperature, humidity, and leakage. This allows for precise tracking and supports proactive maintenance and error detection through its integrated alarm system. Cooler Master's liquid cooling technology is designed for both new and existing data centers, helping managers address the demands of high-performance computing and AI. These solutions enhance performance, energy efficiency, and sustainability, while also reducing operational costs.
