Product Background & Working Principle

As AI computing and supercomputing drive rapidly rising rack power density, traditional air cooling can no longer meet high-load heat dissipation demands. Liquid cooling has become the most reliable and energy-efficient solution for modern data centers and industrial energy equipment. As the core hub of liquid cooling systems, the VENTTK Coolant Distribution Unit (CDU) is cabinet-installed to achieve efficient and cyclic heat exchange. It absorbs heat from IT equipment through secondary-side coolant and transfers waste heat to external chilled water or natural cold source systems on the primary side, precisely maintaining hardware operating temperatures within a safe and stable range. Covering a heat transfer capacity of 350kW to 1500kW, our CDU is purpose-built for large-scale, high-density cooling scenarios.

Integrated Technical Merits

1.Real-Time Intelligent Monitoring & Accurate Thermal Control

VENTTK CDU integrates precision control, ultra-high energy efficiency, wide compatibility and industrial-grade reliability in one compact system. Equipped with a 10-inch color touch screen and multi-level permission control, the intelligent monitoring system tracks temperature, pressure, flow rate and water quality in real time, with anti-condensation protection and precise temperature control accuracy up to ±0.5℃.

2.Energy-Saving Configuration & Excellent Compatibility

Adopting high-efficiency plate heat exchangers and N+1 redundant variable-frequency pumps, the fan-free CDU supports large-temperature-difference operation and significantly reduces overall energy consumption. With strong compatibility, it works stably with deionized water, ethylene glycol and propylene glycol coolants, and seamlessly matches copper, 3-series and 6-series aluminum liquid cooling plates.

3.Corrosion-Resistant Structure & Flexible Communication Options

Built for long-term continuous operation, the entire pipeline adopts 304 stainless steel anti-corrosion fittings. The standard RS485 communication interface provides complete monitoring, alarm and system protection functions. Operating data and alarm records are automatically saved without loss during power failure, while sensors and filters support online maintenance with 25–100μm high-precision filtration. Optional dual power supply further improves operational stability, and customized communication protocols are available for different project needs.

Target Application Environments

Ideal for large data centers, supercomputing centers and high-density green computing clusters, the high-capacity CDU supports new project deployment and traditional data center renovation while being fully compatible with existing chilled water systems. It also delivers reliable thermal management for power electronic equipment and BESS energy storage systems in industrial and energy sectors. By optimizing cooling paths and reducing invalid energy consumption, VENTTK CDU effectively improves overall energy efficiency, helping data center and industrial users lower OPEX and achieve low-carbon, sustainable operation.
