Liquid Cooling for Data Centres
Liquid cooling, or Coolant Distribution Units (CDUs) are utilised in computers, data centres, and various other applications to enhance performance, boost efficiency, and ensure greater reliability.

Liquid cooling for Data Centres
Liquid cooling has become a vital solution for managing the intense heat loads generated by modern high-performance computing (HPC) systems. These applications demand immense processing power, often organised in setups resembling traditional data centres.
Liquid cooling is no longer just a performance booster—it is an essential tool to cope with the thermal challenges of next-generation computing and increasing demands of AI servers and other high-performance hardware. As heat loads continue to rise dramatically, solutions like direct-to-chip cooling are indispensable for sustaining operations and meeting the stringent demands of modern technology.
The process involves a liquid coolant, typically water glycol mixture, that flows through pipework. As it circulates, the liquid absorbs heat from chips or servers and transports it to a heat rejection system, such as free cooling chillers, heat pumps, (adiabatic) dry air coolers or a combination of those.
Why is everyone talking about Liquid Cooling?
The demand for efficient cooling in data centres has accelerated with the rise of AI and large-scale data processing. And it is just the beginning.
As current technologies struggle to keep pace, we have launched Liquid-DENCO CDU – engineered to deliver superior cooling efficiency while significantly reducing total cost of ownership.

Data centres consume significant amounts of electricity, with a large portion dedicated to cooling systems. Efficient cooling reduces this energy consumption, lowering operational costs and minimizing the environmental impact.

Servers and equipment generate substantial heat during operation. Efficient cooling prevents overheating, which can degrade performance or cause throttling, ensuring optimal operation of hardware.

Maintaining stable temperatures prevents wear and tear on components, reducing the risk of hardware failure and downtime, which is critical for uninterrupted service.

Advanced cooling solutions, like liquid cooling, can be made compact than traditional air-based systems, enabling higher hardware density and improved utilisation of space within the data center.
