GT-Liquid Series Cold Plate In Row CDU Cooland Distribution Units 30~600kVA

This in row liquid cooling distribution unit is a high-efficiency solution designed for modern data centers. It is compatible with ASHRAE W4 water temperature design, enabling year-round free cooling across different climates. The system uses built-in pressurized make-up technology to maintain coolant volume, and intelligent anti-condensation control ensures safe and reliable operation of the secondary loop. Its rack-mounted modular design allows flexible installation close to IT heat sources, reducing piping complexity and enabling fast on-site deployment.

Standard dual power supply with 1+1 redundant circulation pumps, minimizing single points of failure.

7-inch capacitive touchscreen with graphical status display and temperature/pressure curves for intuitive monitoring.

Electric proportional control valves combined with variable-speed circulation pumps deliver precise flow control, achieving steady-state temperature accuracy of ±0.3°C.

Supports group control modes with cold standby and hot standby, enabling scheduled rotation, fault takeover, and cascade operation.

Standard quick-connect couplings, with multiple interface options available.

Application

Medium- and large-scale newly built intelligent computing centers; small-scale newly built and upgraded intelligent computing centers; high-density, high-performance computing deployment applications.

GT-Rack Precision Cooling 3.5/5/7.5/12.5kW

Key Technical Characteristics

We provide complete solutions for the entire deployment process of liquid cooling systems, including design, implementation, operation and maintenance.

air cooling vs liquid vooling (1) — Air cooling uses air as the heat exchange medium, relying on fans to circulate cool air and remove heat from IT equipment, and it remains the most commonly used cooling method in traditional data centers.
In contrast, liquid cooling uses liquid as the heat transfer medium to absorb and carry away heat more efficiently, either directly or indirectly from heat-generating components.
With the rapid growth of high-density and high-performance computing, liquid cooling has emerged as a more efficient and energy-saving cooling solution.

Liquid cooling architecture with higher heat transfer efficiency compared to traditional air cooling.
Modular rack-mounted design allows flexible installation at any position within the cabinet.
High-efficiency rack-mounted liquid cooling capacity distribution unit designed for standard cabinets and rack architectures.
