Air is our element - moving it intelligently and efficiently is our passion. Since 1981 the Rosenberg Group has been developing and producing adjustable external rotor motors, fans and air handling units. Our global headquarters is located in Künzelsau, Germany. German Engineering skill is basis of our development work and drives our innovation. As a multinational company, we are represented wherever our customer needs 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.
