The Coilmaster CDU (Coolant Distribution Unit) — purpose-built for modern data centers to deliver precise liquid-cooling control, exceptional reliability, and energy-efficient performance through seamless integration with advanced heat-exchange systems. With configurable components and intelligent controls, it integrates effortlessly into both new and existing liquid-cooling infrastructures.
A coolant distribution unit manages heat transfer between the liquid cooling systems serving IT equipment and the facility water loop. Coolant absorbs heat from high-density servers through cold plates, rear-door heat exchangers, immersion systems, or other liquid-cooled architectures. The CDU then transfers that heat to the facility side while maintaining the temperature, pressure, and flow conditions required by the IT equipment.
Precise control is critical as computing loads change. Coilmaster CDU cooling systems are engineered to maintain stable supply conditions during rapid load changes, helping protect sensitive equipment and support continuous operation. This controlled approach to data center liquid cooling can also improve cooling efficiency and reduce the energy required to manage high thermal loads.
As rack densities increase, effective CDU cooling supports greater cooling capacity within a limited footprint while helping maintain equipment reliability and continuous operation. Coilmaster systems use proven heat exchangers to provide the thermal interface between IT and facility loops while keeping the two circuits separated.
AI and high-performance computing are changing the thermal requirements of modern data centers. Accelerated computing hardware can produce significantly higher rack-level heat loads, increasing the need for liquid cooling systems capable of efficiently removing concentrated heat. Hyperscale and enterprise data centers also need cooling infrastructure that can adapt as capacity and equipment requirements evolve.
Coilmaster CDUs are designed to support these demanding applications with capacities ranging from 500 kW to 10 MW. Configurable in-row, row-adjacent, and centralized deployments provide flexibility for different facility layouts, while modular architecture allows multiple units to be scaled together as site requirements increase.
This flexibility makes Coilmaster CDU cooling suitable for new AI and HPC facilities as well as existing data centers transitioning to higher-density liquid cooling. Coilmaster can configure each CDU to meet the facility’s thermal, hydraulic, and deployment requirements, providing flexibility as cooling demands evolve.
For applications requiring additional facility-side heat rejection, Coilmaster also provides fluid coolers engineered for demanding commercial and industrial heat transfer requirements.
Coilmaster combines heat transfer expertise with configurable and custom engineering capabilities to support demanding data center liquid cooling projects. Our team works with customers to develop CDU solutions around specific thermal, hydraulic, deployment, and integration requirements.
As AI, HPC, and other high-density computing applications continue to increase thermal loads, the coolant distribution unit has become a critical component of next-generation data center liquid-cooling infrastructure.
