Experience in Germany

We have been building and operating data centers in Frankfurt for over 20 years and the city is where our original headquarters was located for Global Data Centers EMEA. With our experience and trust, we ensure high availability while maintaining the highest levels of security to keep client infrastructure and data safe.

Hybrid external air cooling

In our Frankfurt 3 Data Center, the new hybrid external air cooling system has been developed which is a particularly efficient operation to cool computers. The combination of indirect, adiabatic external air cooling and water cooling, known as hybrid external air cooling, fulfills these requirements, while saving approximately ¼ of the cooling energy costs in comparison with pure water cooling with free cooling.

Serving Frankfurt

The Frankfurt 3 Data Center offers the best network connection and a power supply from two different substations with two feeds at 110/20kV level. Frankfurt 3 is located centrally in the Rhine-Main region in Ruesselsheim, about 17 km from Frankfurt am Main Airport. We also operate three additional data centers throughout the Frankfurt area.
