Fans in accordance directive ERP
Energy saving in the use of centrifugal fans
After focusing on improving the efficiency of electric motors, the European Union has defined the regulation 327/2011, on the energy efficiency of fans driven by electric motors with power between 125 W and 500 kW. They published the ErP Directive (Energy-related Product Directive 2009/125 / EC).
This issue is part of the Kyoto agreements, with the ambition to reduce fossil fuel consumption by 20%, to reduce greenhouse gas emissions by 20% and to reach 20% of the share with renewable energies by 2020.
This goal is to assign a level of efficiency “N” to each type of fan, applicable from 01 January 2013, which allows to define a target energy efficiency, knowing that this “N” value will be raised to a higher level from 1st January 2015.
This efficiency objective will then go hand-in-hand with the IE3 efficiency motors commercialization requirement. This Directive applies to fans manufactured or imported and used into the EU, but does not include fans intended for export outside the EU.
From 01st January 2013, only ErP-compliant fans will carry CE marking, while non-compliant fans will not be marked and will be used only for non-EU applications.
Existing fans must not be replaced and only fans marketed after 01.01.2013 are concerned.
Timing of implementation of the ErP Directive
January 01 2013
1st phase
Target energy efficiency applicable for fans between 125 W and 500 kW
Motors between 0.75 and 375 kW: IE2 minimum
=> CE marking only for compliant fans
January 01 2015
2nd phase
Target energy efficiency enhancement for fans between 125 W and 500 kW
Motors between 7.5 and 375 kW: IE3 minimum, or IE2 if driven by frequency converter => CE marking only for compliant fans.
January 01 2017
3th phase
Target energy efficiency enhancement for fans between 125 W and 500 kW
Motors between 0,75 and 375 kW: IE3 minimum, or IE2 if driven by frequency converter => CE marking only for compliant fans.
In most of the cases, the fans from AIRVISION range already comply with these new regulations, and many applications are exempted from ErP-compliant fans, including:
– High power fans > 500 kW at the maximum efficiency point of the fan.
– Fans designed to process gases over 100 °C.
– Fans designed to process corrosive, toxic or abrasive gases
– ATEX fans used in case of emergency (smoke extraction 400°C/2h, 300°/1h etc.)
– Etc.
