Cooling
The numerous servers, storage systems, network equipment, and other critical infrastructure of data centers generate huge amounts of heat during its operation. Such heat may lead to equipment failures, reduced performance, and increased energy consumption if it is not properly managed. Therefore, effective cooling systems are crucial to ensure the reliability, efficiency and sustainability of data center operations. From planning to installation and maintenance, our experts are by your side to find the best solution to optimise your PUE.
Cool down and let us face your challenges
Data centers face several challenges when it comes to cooling systems. These challenges include degassing, maintaining top water quality, managing pressure, using effective separators as well as an energy-efficient operation. Degassing is essential to remove dissolved gases that can cause corrosion and reduced heat transfer efficiency. Pressure management is crucial for maintaining proper flow rates and system stability. Separators are necessary to remove impurities from the cooling water. Energy efficiency is becoming increasingly crucial in reducing both PUE (Power Usage Effectiveness) and WUE (Water Usage Effectiveness) as data centers continue to be substantial consumers of energy. At Wilo, we understand these challenges and have the products and expertise to overcome them.
Liquid Cooling
Liquid cooling involves the use of liquid, typically water or specialised coolant, to directly remove heat from the components within the IT infrastructure. In liquid cooling systems, heat is transferred directly from the IT components, such as processors or graphics cards, to a liquid coolant that circulates through the system. This allows for more efficient heat dissipation compared to traditional air-cooling systems.
Common liquid cooling methods include:
- Direct-to-chip Cooling
- Immersion Cooling
- High-density Cooling

Direct-to-chip Cooling
Direct-to-chip (cold plate) cooling is an advanced cooling technique that utilises the circulation of a cooling liquid directly through a cold plate, establishing direct contact with critical heat-generating components like CPUs and GPUs in IT devices. By doing so, this method efficiently dissipates heat from these components, resulting in highly effective cooling.
Immersion Cooling
Immersion cooling is a liquid cooling technique used to regulate the temperature of data center equipment by submerging it in a cooling fluid. By immersing servers in a cooling liquid, heat is efficiently dissipated, promoting optimal performance of components such as CPUs and GPUs. Immersion cooling systems are known for their superior efficiency compared to traditional data center cooling methods, thanks to the higher thermal conductivity of most liquids in comparison to air.
High-density Cooling
The Rear-Door Heat Exchanger is a cooling solution for high-density data centers. It uses radiator-like doors at the back of the racks to cool a 20kW rack using chilled water. The server exhausts hot air through the heat exchanger, which transfers the heat to liquid coolant. The coolant then goes to cooling towers connected to an external chilled water system, cooling the air before it returns to the data center space.
Hybrid Cooling
Hybrid Cooling is an innovative approach that combines multiple cooling technologies to create a highly efficient and sustainable system for managing heat in data centers. Thanks to its high flexibility, hybrid cooling allows for the combination of a variety of cooling technologies in both primary and secondary water systems. The hybrid system intelligently selects the most suitable cooling method based on the specific heat load and ambient conditions which leads to impressive energy savings.
Air Cooling
Air cooling involves the circulation of cool air within the data center to dissipate heat and maintain optimal temperatures. The air cooling systems are carefully designed with a combination of refrigeration, air distribution, control systems and cooling water circulation systems to ensure stable cooling, minimise hot spots, and optimise energy efficiency. The industry-standard approach for air cooling in data centers involves the use of computer room air conditioning (CRAC) units or computer room air handlers (CRAH). These systems are specifically designed to maintain the desired temperature and humidity levels within the data center environment.
