Horizontal Coolant Distribution Unit (CDU) for AI Data Centers and High Density Liquid Cooling
High Performance Horizontal Coolant Distribution Unit for AI Data Centers and HPC Liquid Cooling
The Horizontal Coolant Distribution Unit (CDU) is a high-capacity liquid cooling solution designed for AI data centers, HPC clusters, GPU servers, edge computing facilities, and other high-density thermal management applications. The horizontal cabinet structure provides a compact footprint while maximizing cooling capacity, making it ideal for installations with limited equipment room height or specific project layouts.
The CDU isolates the facility water loop from the technology cooling loop through a high-efficiency plate heat exchanger, ensuring stable coolant temperature, pressure, and flow while protecting sensitive IT equipment from contamination. Equipped with intelligent PLC control, redundant pumps, and comprehensive monitoring functions, the system delivers reliable 24/7 cooling performance for mission-critical infrastructure. Modern CDUs have become a key component in direct-to-chip liquid cooling architectures for AI and HPC environments.
