Introduction

    The Coolant Distribution Unit (CDU) is the core component of the water cooling system, responsible for efficiently distributing the coolant to meet various cooling needs. By integrating auxiliary monitoring and support devices, the CDU ensures stable operation of the system.
    It is mainly used for heat exchange control in liquid cooling systems, incorporating secondary side variable frequency circulating pumps, plate heat exchangers, electric control valves, temperature sensors, pressure sensors, filters, expansion tanks, flow meters, and online replenishment functions. The CDU is pre-installed and debugged at the factory, reducing on-site installation and commissioning work.

Our Advantages

    With Venttk's innovative design, the CDU optimizes the performance and reliability of the water cooling system. It features six channels that connect the main circuit to the secondary water distributor of the water-cooled cabinet, reducing installation and production errors with the use of chucks and rubber hoses.

    Venttk's CDU incorporates a multi-stage centrifugal pump for industrial water circulation, ensuring efficient and reliable coolant flow. An integrated expansion tank compensates for temperature fluctuations, maintaining stable pressure levels and ensuring reliable system operation.

    To prevent issues such as oxidation corrosion, poor circulation, and cavitation of the circulation pump, the CDU includes an automatic air vent valve on the top of the makeup water tank/main pipeline, which promptly eliminates non-condensable gases from the system. 

    Additionally, the CDU is equipped with a 150μm filter in the main path to protect the quality of the coolant, ensuring the reliable and stable operation of the entire system.
