Data Center Cooling Solutions
ENGINEERED SOLUTIONS FOR MISSION CRITICAL APPLICATIONS
For data centers seeking to use less energy, free cooling solutions that use naturally cool air or water, instead of mechanical refrigeration, are increasingly attractive options.
Factors such as the maximum temperature required for the servers, and the availability of water will influence which free cooling system to choose. Typical heat rejection systems include dry air coolers, adiabatic dry coolers, hybrid coolers and cooling towers.
Space, power and cooling are the three essentials for effective data center operation. CRAH systems offer a competitive solution for the data center industry as they are simple to mount and have the flexibility to be designed to suit specific needs.
In considering a CRAH system, it is important to take into account – at the design stage – the available space,aisle widths, ceiling heights, coil configurations and the air flow requirements of computer manufacturers, as well as system redundancies.
The different ways of adopting liquid cooling all need to be weighed against the characteristics of the fluids, the type of system, design, costs and available space.
It is clear that you need to consider the design as a whole and select the heat exchanger that is best suited to the performance requirements and specifications.
It is therefore recommended that you find a partner that can offer an extensive portfolio, backed by quality and experience, and that can tailor the coil or plate configuration to suit your application.
Finding the right solution brings peace of mind as it ensures that your system will run efficiently while having a positive impact on your total costs.

Customised coolers support Mainova WebHouse data centre
Mainova WebHouse is developing an environmentally friendly data centre in Frankfurt that will help customers and the city achieve their climate protection goals. Sustainability and energy efficiency were paramount when choosing suppliers and Kelvion cooling technology was way ahead in meeting these requirements.
Data Centre Reference
Green electricity
The new data centre is the first for Mainova WebHouse, a subsidiary of German regional energy company Mainova, which supplies more than a million people with electricity, gas, heat and water.
As part of the company’s commitment to decarbonization, the data centre campus will be supplied with 100% green electricity. Built with LEED-Gold certification, the new facility will reuse waste heat to power other buildings in the area.
