Rosenberg

Company Profile - The Rosenberg Group

Air conditioning and ventilation technology is our world

Air is our element – moving it intelligently and efficiently is our passion. Since 1981 we have been developing and producing adjustable external rotor motors, fans and air handling units.

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 continuous exchange of information between customers and employees comes first with us. Consequently, we can permanently optimise products and quality to respond flexibly to all of our customers’ needs.
 

Our success factors

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.
 

About 1,400 qualified and experienced employees are employed in the punching plant, casting plant, as well as in the motor, fan, and air handling unit production to ensure immediate assembly and quick delivery.  
Through a combination of human know how and innovative production technology we achieve a quality which meets the highest requirements.
 

Our claim - we stand for uncompromising quality

We do not make any compromises on the quality and reliability of our products. We have obtained certification according to DIN EN ISO 9001, Eurovent certification (series Airbox F40 and T60) as well as being members of the RLT-Herstellerverband Raumlufttechnische Geräte, the German manufacturers’ association for ventilation and air conditioning equipment, which confirm our expertise and know how in the development and production of ventilation equipment.

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. Therefore the reliability and accuracy of the Rosenberg measurement equipment, and hence the accuracy of the products’ performance data have been confirmed by an independent body. The tested data and curves are the sole basis for our product catalogues and selection program.
