Since 1981, Rosenberg Ventilatoren GmbH, based in Künzelsau-Gaisbach (D), has developed into an important European centre for the ventilation and air-conditioning industry through the development and production of controllable external rotor motors. The production of all parts, from motors and fans to control systems and complete box air conditioners, enables Rosenberg to be independent of suppliers. With around 1,400 employees worldwide, Rosenberg Ventilatoren GmbH has become a competitive medium-sized company. Over the past 35 years, the Rosenberg Group has expanded its European operations by seven additional plants and shareholdings in France, Italy, Hungary, the Czech Republic and Germany.
