Rosenberg's energy efficient EC fans already fulfil the efficiency values of the ErP regulations

Top Quote With the Ecodesign Directive 2009/125/EC (ErP Directive) the European Union has defined the requirements to the environmentally configuration of energy using products. End Quote
  • (1888PressRelease) September 30, 2011 - This directive is part of the 20-20-20 target, according to which energy use shall be reduced by 20% and the share of renewable energies shall be increased by 20% until 2020. It replaces the EuP Directive 2005/32/EC which had only related to a selection of electrical products.

    Concrete measures will be defined through more detailed regulations. In the first stage, starting January 01, 2013, fans in range of input power of 125W to 500kW have to meet specific values of efficiency. On January 01, 2015, the second stage with higher efficiency values enters into effect.

    Thereby considered will be the entire fan, not just the single fan motor. Compliance with all efficiency requirements is condition for utilisation of the CE symbol.


    Starting June 2011, IEC-motors have to comply with the requirements of the regulation (2009/640/EC) and have to reach at least efficiency class IE2 (earlier called: eff1).

    IECmotors of a lower efficiency class will no longer be allowed to be marketed within Europe. Therefore Rosenberg has already completed converting all fans with IEC-motor to IE2-level. These are clearly indicated in the latest price list 2011.

    External rotor motor

    External rotor motors are not affected by this regulation; they are usually used as fan motors and these fans have to comply to the ErP Directive for fans (2011/327/EC) with efficiency values starting beginning of 2013.

    EC technology
    Rosenberg's energy efficient EC fans already fulfil the efficiency values of the ErP regulations. They are 100% ErP ready!
    In comparison to conventional AC fans, considerable higher efficiency levels of more than 90% will be reached due to the motor effectiveness. EC fans are easily speed controllable by the integrated electronics through which very high energy saving potentials can be achieved. As a result, the air volume can be adjusted to every possible operating point.

    The integrated intelligent electronics does not only enable speed control but also additional functions like for example airflow-/pressure- or air quality-control. Rosenberg EC fans fulfil highest demands regarding energy efficiency and economic efficiency.

    You will find further information on our EC standard fans in our brochure "Standard fans with energy efficient EC technology" which we will send to you upon request.
