2 OBJECTIVES

ErP DIRECTIVE - OBJECTIVES“ErP” stands for “Energy related Products”. The associated Directive supports the aims of the EU Climate and Energy Package by encouraging the use of environmentally friendly designs (“Eco design”), in order to reduce greenhouse gas emissions by 20%, whilst also increasing the use of renewable energy sources within the EEA (up to 20%) by 2020.

However, the main focus of the ErP directive is to increase product energy efficiencies by 20%. This ethos is also known as the “20-20-20” target. Although the ErP Directive only applies within the EEA, others often adopt European legislation as best practice, especially as the Directive is based upon the internationally recognised climate change agreement, the Kyoto Protocol.

For this reason, within the main ErP Directive 2009/125/EC, applicable standards have been developed for each specific product group for use within the EEA. For fans, the Commission’s regulation (EU) 327/2011 (also known as lot 11), applies. Electric motors and their construction are covered separately by Regulation 640/2009.

Products AffectedThere are some exceptions, but most energy using products will be affected by this ErP Directive. Electric motors are of specific interest to fan manufacturers as these are core to all ventilation products. Regulation 640/2009, which sets the minimum efficiency requirements for electric motors, came into effect on 16th June 2011 and related to electric motors rated between 0.75kW and 375kW.

On 1st January 2015, efficiency targets for electric motors were increased. Revised efficiency grades (as detailed below) apply to an amended IEC output rating range of between 7.5kW and 375kW inclusive.

Although regulation 640/2009 does not apply to airstream rated motors (which is our standard), where IEC power rated motors are used (within bifurcated fans for example) it is a legal requirement to use IE3 motors, or IE2 motors with a variable speed drive. Where airstream rated motors are used, IE2 or even IE1 efficiency grade motors can be used as long as the combined fan and motor efficiency is greater than that defined within the fan regulation 327/2011.

Regulation 327/2011 Requirements All fan products incorporating motors which have an electrical input power of between 125W and 500kW are within the scope of this regulation.

Fans are rated taking into account the combined motor and impeller efficiency to give an FMEG rating (Fan Motor Efficiency Grade) - also referred to as “N” grade, which is then checked against the minimum pass grades stated within the 327/2011 regulation (see table 1 on page 4) and used to determine if the complete product meets the target efficiency to enable it to be sold and used within the EEA. On the 1st January 2015 the second efficiency tier came into effect. 2013 targets are shown for reference. Manufacturers are legally required to ensure that their products comply with this legislation.

ErP Compliant Product Identification Products that do not meet their required FMEG rating will therefore not be ErP compliant, which in turn means that a CE mark cannot be affixed to them. The CE Mark is a legal requirement for products sold into the EEA.

For products which comply, there is a legal requirement to affix a label which shows 5 key pieces of ErP related information, the FMEG N grade, the measurement category, the efficiency category and the overall efficiency of the product at its optimum energy efficiency point and if applicable, confirmation that the calculation of fan efficiency is based on the use of an Inverter (VSD). In addition, the range of compliant impeller pitch angles will be stated.

Although products which are ErP compliant will of course display a CE mark, Flakt Woods products will also display a distinctive “ErP compliant” logo to help customers identify compliant products. This logo will also be used in all relevant marketing material, selection tools, and packaging to assist in positive identification of compliant products.

Regulation Exemptions and AllowancesSome fans which are designed to be used in particularly hazardous conditions are not required to comply with this directive. ATEX fans, high temperature fans (operating continuously at temperatures above 100°C) or Smoke Extract fans designed for single emergency use operation are the most common exemptions.

20% LESS CO

+

Dual Use and Dedicated Smoke Exhaust FansWhere Smoke extract fans are used ONLY when an emergency condition exists, then they do not need to comply with the ErP regulation. If however, fans are “dual use” and are designed to provide normal ventilation and short-term emergency Smoke Extraction, then these fans do need to comply, but can have additional grade allowances applied to compensate for the increased running clearances (impeller tip gaps) required in such products.

When the first tier was applied (as from 1st January 2013) the target grade could be reduced by 10%

However, when the second tier was enforced on the 1st January 2015 the increased target grade can now only be reduced by 5%

Fans integrated into kitchen hoods also get a dispensation by way of increasing the threshold input power from 125W to 280W.

This allowance does not apply to general kitchen applications, as the fan must be an integral part of the hood itself.

Fans Fitted Within Other ProductsRegulation 327/2011 for fans was produced under lot 11 during the implementation of the ErP directive. An additional product group for ventilation units is being addressed under lot 6. In the same way that electric motors installed into fans must comply with Regulation 640/2009, then fans that are used within other ventilation products must still comply with regulation 327/2011.

As further Lots are issued, products will have to comply with multiple requirements, i.e. the fan inside a box fan unit will have to comply with Lot 11, whilst the complete unit will also have to comply with Lot 6.

Replacement of Non Compliant FansNon-compliant products cannot be sold as replacements into building service type applications.

The only circumstance where a non-compliant product can be supplied within the EEA is where spare parts are being provided for a fan that was originally shipped before 1st January 2015.

In such a case, it is possible to supply spare parts required to affect a repair. The only exception however is spare impellers, which cannot be supplied as non-compliant variants.

If a replacement impeller is required for a fan supplied before 1st January 2015, then the customer should instead purchase a new and fully compliant fan.

4 TARGETS

Enforcement Date and ImpactAs mentioned previously, the second tier of Regulation 327/2011 came into effect on 1st January 2015, but how will this impact upon manufacturers and consumers of Energy related Products?

Regulation 327/2011 states that products that are placed on the market, or put into service, after this date must be compliant. To place a product onto the market it must either be physically handed over or the transfer of ownership must have taken place.

A product has not been placed on the market if it is held in stock by the manufacturer. If a subsequent alteration is made to a product after 1st January 2015, it will have to comply with the requirements of the regulation in its revised state. The modifier is then responsible to ensure its compliance.

Grading ProcessThe minimum FMEG pass grade requirement is dependant on the fan type and how it will be installed.

The ErP Directive states different minimum FMEG grades per fan type (Centrifugal Forward curved, Backward curved, Plug fans, Mixed flow and Axial fans). Each of these are further differentiated by test category, of which there are 4. (A to D).

These are defined in detail in table 1 (see previous page). Table 2 states the calculation methods used and target FMEG ratings per fan type.

We believe that optimal fan efficiencies are most likely to be achieved, when the actual fan N grade is calculated and tested against the measurement and efficiency category, which relates most closely to the intended installation method.

Table 2 – 2015 ErP Targets

There are multiple ways of meeting the required minimum FMEG grades. Many manufacturers use EC (Electronically Commutated) motor technology as a solution, as these typically have higher efficiencies than AC motors.

This, however, is not the whole story as the legislation measures the entire fan, not just the motor. Fitting an EC motor does not therefore automatically mean that the fan will be compliant, as it may be using a very inefficient impeller. Similarly, by using high efficiency impellers, there maybe no need to rely upon EC technology in order to reach the required grades.

The Directive allows the use of Variable Speed Drives (VSDs) and prescribes that a small efficiency loss allowance can be applied when VSDs are used. This could in some cases mean that the resultant FMEG rating is improved to a pass level, when a more efficient VSD is combined with a given fan and motor combination.
