Reliable cooling. Efficient by design.

75 kW Liquid-to-Air In-Row CDU

Overview The Cooler Master 75 kW Liquid-to-Air CDU is a breakthrough cooling solution engineered for high-density IT environments. Designed to fit seamlessly into hot/cold aisle configurations, it delivers up to 75 kW of thermal dissipation with an approach temperature difference of 12.2°C at 50 LPM using dual V-pattern radiators and 16 hot-swappable fans, all within a 44U rack footprint. Built for reliability and scalability, the CDU features redundant dual-pump modules, modular power supplies, and intelligent sensor arrays for real-time monitoring. Whether deployed in AI clusters, HPC racks, or retrofitted into existing infrastructure, this CDU offers a powerful, space-efficient answer to modern data center cooling demands. The Cooler Master Liquid-to-Air CDU features numerous sensors that measure flow, pressure, pH, turbidity, conductivity, temperature, relative humidity, and leakage, enabling accurate monitoring of fluid conditions. Operators can use CDU performance data to support actionable decision-making on preventive maintenance, address potential errors or malfunctions, and respond to alarms from the CDU's integrated alarm system.
