Rosenberg Axial Fans are mostly used in Air heaters, Heat pumps, Condensers, Cooling units, Evaporators and Chillers. The fans are suitable for handling air and other non-aggressive gases or fumes.

Rosenberg EC Axial Fans with profiled and noise optimized blades, made of die-cast aluminium, combined with electronically commutated motors (EC-motors), form a very efficient and design optimized fan unit. The Fans are available in sizes 500 – 1000 mm impeller diameter.

The main concern for Rosenberg EC Axial Fans was to keep noise emission low in the main range of application of the fan while having an optimal performance curve with the long and short nozzled inlet cone.

Custom designed EC motors, flexible production of blades and high end metal fabrication, gives Rosenberg the capability to manufacture fans that provide the best possible benefit to customers while taking the design demands and the customer’s application into consideration.

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 Kuenzelsau (Germany). As a worldwide company we are represented in more than 45 countries.

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.

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.

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.
