Introduction

The Coolant Distribution Unit (CDU) is a crucial component in cooling systems, primarily functioning in the secondary side of the circulation.
In a typical cooling system, there are two main loops: the primary side and the secondary side. The primary side is usually connected to the main cooling sources such as chillers or cooling towers, which provide the initial cooling medium. The secondary side is connected to the equipment that requires cooling, such as servers, electronic devices, etc., ensuring these devices operate at optimal temperatures.

The CDU plays a vital role in the secondary side by distributing the cooling medium from the primary side to the equipment needing cooling, achieving efficient heat exchange. Its core components include variable frequency circulating pumps, plate heat exchangers, temperature and pressure sensors, filters, expansion tanks, and flow meters. The CDU not only ensures effective distribution of the coolant but also provides online liquid replenishment, maintaining system stability.

Additionally, the CDU features an intelligent control system that can monitor and adjust temperature, flow, and differential pressure in real-time, preventing condensation and supporting various communication protocols for seamless integration with other systems. Its corrosion-resistant, high-quality materials and modular design make it suitable for various industrial and commercial environments, ensuring efficient cooling and long-term operation of equipment. Choosing a CDU means opting for an efficient and reliable cooling solution.

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.
