Energy efficiency

The maincubes FRA01 relies on an open-air cooling system using innovative Kyoto cooling. Thanks to this new type of cooling, the PUE value of the data center can be reduced to a value of 1.3 and less. Which enables you to operate in a more cost-efficient and environmentally friendly manner.

For comparison: The average PUE value in german data centers was 1.7 in 2018.


For security, the maincubes FRA01 relies on multi-level access controls with vein scanners, camera surveillance and a security service that is on site 24 hours a day. In addition, the data center has comprehensive fire protection thanks to a CO2 extinguishing system and early fire detection.

In addition, the maincubes FRA01 data center is TÜV-tested and certified according to ISO/IEC 27001:2013 and ISO 9001.
