The need for data centers to house computer systems is rapidly increasing, with a resulting rise in energy consumption. However, solutions are at hand that will help keep consumption down. A data center owner has had highly efficient cooling units, which use Danfoss technology, installed and now saves 33% energy annually.

Quite a lot of the energy consumption in a data center is used for heat removal, to keep data safe at the right temperature and humidity. Eaton-Williams, a climate solutions company, has installed cooling units for a scalable data center, which use Danfoss variable speed compressors. This has resulted in an excellent power usage effectiveness rating of 1.21 for the data center.

In a recent survey, the average rating of more than 500 data centers was 1.8. The low power use means that the owner saves 33% energy and 1.5M EUR annually.

The installation in the data center consists of 12 highly efficient cooling units, each supplied with multiple variable-speed fans and compressors in order to minimize energy use and ensure quick and precise temperature control. For security reasons, we cannot reveal the name and the location of the data center, because the information managed by the servers is often very sensitive.
