Air is our element – moving it intelligently and efficiently is our passion.

Our headquarters is located in Künzelsau. German Engineering skill is the basis of our development work and drives our innovation. As a worldwide company we are represented where our customers need us. The complete range of motors, fans and air handling units is mainly manufactured in the Rosenberg Group’s own production sites.  From technical advice via assembly to delivery of air handling units that are wired ready for connection, the customer receives all services first-hand from the Rosenberg Group. 

Our production steps – from motor to controller – make us more independent from suppliers and allow us to respond flexibly to our customers’ wishes. In short: We are good at troubleshooting.  We are already in direct contact with the customer during the development and planning phase and therefore we can fulfil special requirements quickly and on an individual basis. Our aim is to ensure that our clients are satisfied. 

In our own company laboratories we have modern measurement equipment at our disposal to measure and analyse the flow and sound characteristics of our fans and air handling units.  Our test chambers for recording performance characteristics are tested and certified by TÜV Süd according to the European standard DIN EN 5801.
