Leading the way

Made in Germany

Our energy saving EC-motors are developed and manufactured exclusively on our modern production line at our headquarters in Künzelsau. Through the combination of know-how and innovative manufacturing technology we attain a quality that meets the highest standards.

Energy-related Products Directive(ErP)

The European Union mandates the minimum energy efficiency requirements for energy using products with the Energy-related Products Directive 2009/125/EG (ErP). Rosenberg EC-fans are 100% compliant and fall below all maximum permissible values.

Tested precision

Modern measuring systems are available in our own company laboratories. Here electrical, fluidic and circuitry related properties of our fans and air handling units can be measured and analyzed. Our testing chambers are regularly inspected and certified by TÜV Süd according to DIN EN ISO 5801. Through this an independent entity confirms the reliability and accuracy of the testing equipment used and hereby confirms the precision and performance data of our products.
