Erp directive FAQ

ErP - why and what is it?

ErP is an abbreviation for Energy Related Products Directive. The objective with the directive is to reduce electrical energy consumption, forcing the market to use eco-correct components as regards efficiency. Less energy consumption means less pollution and consequently a cleaner and more sustainable world!

How does the ErP Directive 2009/125/EC involve Multi-Wing products and customers?

By regulation EU 327/2011 (specific fan regulation inside ErP’s big basket) fans driven by electric motors are classified as widely diffused electric consumption devices that need an Eco-design regulation. Our customers who produce complete fans have to comply with the new minimum standard of efficiency (a complete fan is treated as “final assembly fan” in the directive): fan, motor, and structure’s design contribute to reach the target of the regulation.
The fan component is classified as part of an electric fan (as “not final assembly”) with reference to regulation EU 327/2011. When the fan is coupled to an electric motor inside a product (machine different from the fan) which is not a ventilator, also the fan has to be ErP compliant. The regulation states conditions and equations to measure, calculate and certificate the fan in regard to the minimum efficiency target.

Who is subjected to Regulation 327/2011?

Directly: companies that produce electric fans (supplied as final assembly) and companies that produce fans (part of fan defined as "not final assembly ").
Indirectly: all manufacturers of products that contain fans or parts (fans coupled to an electric motor). These companies have to install fans or part of fans in accordance with the ErP Directive.

Which markets are involved?

The directive is valid for manufacturers of the involved products and components located within European Union (EU). Imported products have to be compliant with the directive as well, exported products are not involved.

What’s the timeframe for Regulation 327/2011?

There are two defined tiers.
Tier 1, from 01/01/2013. An overall minimum efficiency limit has been set.
Tier 2, from 01/01/2015. Increased minimum efficiency limits compared to Tier 1.

Are there any exceptions to regulation 327/2011?

Fans driven by motors with an electric input power not between 125 W and 500 kW
Fans designated for export out of the EU and does not apply to means of transport for persons or goods
Fans designed specifically to operate in explosive atmospheres*
Fans designed for emergency use only, at short-time duty*
Fans in toxic, highly corrosive or flammable environments or in environments with abrasive substances
Fans designed specifically to operate where operating temperatures of the gas being moved exceed 100 °C*
Fans designed specifically to operate where operating ambient temperature for the motor, if located outside the gas stream, driving the fan exceeds 65 °C*
Fans designed specifically to operate where the annual average temperature of the gas being moved and/or the operating temperature for the motor, if located outside the gas stream, are lower than – 40 °C;*
Fans with a supply voltage > 1000 V AC or > 1500 DC*
Fans placed on the market before 1 January 2015 as replacement for identical fans integrated in products which were placed on the market before 1 January 2013**
Fans designed to operate as at optimum energy efficiency at 8000 rotations per minute or more
Fans designed to operate as conveying fans used for the transport or non-gaseous substances in industrial process applications
For dual use fans designed for both ventilation under normal conditions and emergency use, at short-time duty, with regard to fire safety requirements the 2013 requirements is reduced with 10% the 2015 requirements with 5%
Small fans (indirectly) driven by an electrical motor between 125 W and 3 kW which primarily serves other functionalities. E.g. an electrical motor in a chain saw even if the motor of the chain saw itself is above 125W.
Fans integrated in products with a sole electric motor of 3 kW or less where the fan is fixed on the same shaft used for driving the main functionality Fans integrated in laundry and washer dryers ≤ 3 kW maximum electrical input power
Fans integrated into kitchen hoods < 280 W total maximum electrical input power attributable to the fan(s)

Does the Directive also involve existing installations?

No, existing installations are not affected

Is Multi-Wing able to help in regard to ErP?

Multi-Wing started more than two years ago analysing and understanding the new EU efficiency challenge.
Today we are ready with:
• A wide range of ErP compliant fans (2013 and 2015) and with all the necessary formal documentation as required and defined in the EU Regulation 327/2011.
• An EU confirmed approach for supporting non fan package customers selecting and documenting compliant fan & motor combinations. This requires no additional testing.
• An approach to support fan manufactures predict the compliance for their entire product portfolio. This approach requires that all distinct fan package designs have been tested by the fan package producer.
Using our new powerful tools we can help select, analyze and verify ErP compliance and after the selection process we can support with the required ErP documentation and EC Declaration of conformity.

Does it matter that your measurement category is different from mine?

Yes it matters, however, target efficiencies are listed for both AMCA A, B, C & D in the EU Regulation 327/2011 meaning that it takes the different measurement categories into account . For AMCA A & C the efficiency targets are lower as this measurement category only accounts for the static efficiency, whereas measuring in accordance to AMCA B & D you also gain the contribution from the dynamic efficiency. Therefore efficiency targets for AMCA B & D are higher. At Multi-Wing we measure in accordance to AMCA A. We have detailed information on both the static and the dynamic efficiency of all of our fans.

Are we all required to test?

No. However, you are responsible for meeting the law.

What verification procedure will be followed by EU?

When performing the market surveillance checks referred to in Article 3(2) of Directive 2009/125/EC, the authorities of the Member States shall apply the following verification procedure for the requirements set out in Annex I. 1. The authorities of the Member State shall test one single unit. 2. The model shall be considered to comply with the provisions set out in this Regulation if the overall efficiency of the fan (ηe) is at least target energy efficiency*0,9 calculated using the formulas in Annex II (Section 3) and the applicable efficiency grades from Annex I. 3. If the result referred to in point 2 is not achieved: — for models that are produced in lower quantities than five per year, the model shall be considered not to comply with this Regulation, — for models that are produced in quantities of five or more per year, the market surveillance authority shall randomly test three additional units. 4. The model shall be considered to comply with the provisions set out in this Regulation if the average of the overall efficiency (η e ) of the three units referred to in point 3 is at least target energy efficiency*0,9 using the formulas in Annex II (Section 3) and the applicable efficiency grades from Annex I. 5. If the results referred to in point 4 are not achieved, the model shall be considered not to comply with this Regulation.

Does EU provide support for testing?

No economic support for testing products because you are responsible. It is the law.

What criteria must the law meet?

DIRECTIVE 2009/125/EC specifies that implementing measures shall meet all the following criteria:
(a) there shall be no significant negative impact on the functionality of the product, from the perspective of the user;
(b) health, safety and the environment shall not be adversely affected;
(c) there shall be no significant negative impact on consumers in particular as regards the affordability and the life cycle cost of the product;
(d) there shall be no significant negative impact on industry’s competitiveness;
(e) in principle, the setting of an ecodesign requirement shall not have the consequence of imposing proprietary technology on manufacturers; and
(f) no excessive administrative burden shall be imposed on manufacturers.
