Eislingen/Fils, May 13, 2026 – On April 28, 2026, Salvia Building Technology signed an agreement to acquire a majority stake in the Hand & Werk Group. The transaction is still subject to approval by the German antitrust authorities; closing is expected in the coming weeks.
The Hand & Werk Group, together with MJS Airklima GmbH & Co. KG, has been active in data center construction for several years under the dcblue Datacenter Experts brand. Through this collaboration, numerous demanding projects in the data center environment, particularly in the Rhine-Main region, have been successfully completed.
As part of the transaction, MJS Airklima GmbH & Co. KG will be integrated into the Hand & Werk Group. At the same time, the existing holding structure will in future operate under dcblue GmbH. This will create a unified market presence for the joint activities in data center construction.
