Maximize your data center’s cooling with Coolnet’s CDUs. Designed for AI and HPC, our rack, row, and large liquid-cooled CDUs offer dual-pump redundancy, smart PLC control, and high efficiency.

Coolnet focuses on the research and development of data center cooling products, offering a full series of solutions from liquid-cooling racks, CDUs, manifolds, immersion tanks, and prefabricated piping to primary side cooling sources. The integrated design of dry coolers and supplementary cooling units—where air-cooled and liquid-cooled modules share a set of cold water trays—significantly reduces costs, saves space, and facilitates seamless on-site installation.


Highest density Coolant Distribution Units (CDU) are engineered to meet the most demanding direct liquid cooling requirements for Artificial Intelligence (AI), High-Performance Computing (HPC), and enterprise computing applications.
Coolnet’s CDUs deliver exceptional performance, density, efficiency, and reliability for data centers with or without facility water infrastructure.
In a server cooling system, integrated CDUs enable greater processing power density, meaning more servers can fit in each data center rack. Integrate CDUs directly into facility water systems for direct rack server cooling, or design self-contained cooling that offers the next level of flexibility for liquid-cooled servers.
Liquid-to-Liquid CDUs require facility water to remove heat from rack and row equipment but come with a battery of benefits to offset added system complexity. Fully liquid-cooled data centers maximize energy efficiency from the higher heat capacity of liquid throughout the entire infrastructure.


In large data centers, place the CDU in the equipment room and connect the cold plate server cabinets through pipes. The outdoor unit acts as a cooling tower or dry cooler, efficiently managing massive thermal loads.
