We are very happy about winning 1st place at the German Data Center Awards 2018 in the data center cooling & climatization category for cooling data centers using CPU heat.

The prize was awarded for our adsorption cooling technology which uses the low temperature residual heat from servers for cooling air-cooled components, or for air conditioning the data center itself. By re-using the server heat, instead of electric power, to drive chillers, the technology can save up to 90% of the electricity required for cooling.

The technology is based on our zeolite crystallization process, which makes adsorption feasible at the low drive temperatures typical for CPUs, from around 50°C. The technology is already in practical use at the Leibniz Supercomputing Centre’s CoolMUC-2, and it will soon be implemented at a much larger scale for the new SuperMUC-NG by Lenovo, which will become operational from the fall of 2018.

The award ceremony was held as part of the German data center convention “Future Thinking” in Darmstadt on April 24, 2018. There have been 51 submissions among all 8 categories; the cooling & climatization category was the most heavily contested one with a total of 13 applications.
