Leading the way with energy efficient EC technology

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 in Germany. 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.

Overview of the advantages

1. high efficiency factor
2. low energy consumption
3. integrated monitoring function
   (motor temperature, locked rotor and many more)
   
4. easy installation and connection (Plug & Play)
   
5. expanded functionality (pressure control and many more)
6. compact construction

Energy Efficiency

Our engineers and technicians are constantly working on improving the energy efficiency of our products - with success. Our motors with modern EC-technology achieve efficiency ratings over 90% and save up to 50% energy versus traditional motor technology. In comparison to EC 60034-30, Rosenberg EC-motors have an efficiency rating greater than IE4. The lower energy consumption is not only good for the environment, but lowers the operating costs for our customers.

Expanded Functionality

The EC-technology offers more than just efficiency. Rosenberg EC-motors are maintenance free and low-noise. In addition, the integrated, intelligent electronics take care of control, communication and monitoring functions. Steplessly variable speed settings are possible as well as the creation of pressure, air flow and air quality parameters. Parameters essential to the proper operation, i.e. voltage or temperature, are monitored automatically. With this, our EC-products meet the highest standards in regards to energy efficiency, cost effectiveness and high air quality.

Amortization

Quality pays for itself. The slightly higher investment costs compared to conventional motors is usually amortized within a short operating time due to lower energy consumption und greater ease of installation (no transformer controller, motor overload switch, thermocouple meter, VFD, or phase angle controller are necessary).
