ErP Directive and Regulation (EU) 327/2011

Industrie CBI S.p.A.CBI Group Headquarters

The Commission and the European Parliament, in accordance with the Kyoto Protocol which provides for a 20% reduction of CO2 emissions into the atmosphere by 2020, have issued several directives and regulations with a view to implementing the agreements on the reduction of energy consumption.

In this context Directive 2009/125/EC (ErP Energy-related Products) of 21 October 2009 was issued by the European Parliament and by the Council for the establishment of a legislative framework for the setting of ecodesign requirements for energy-related products.

The criteria for application of the Directive are inserted into appropriate regulations dedicated to the different types of products.

As for fans, the European Commission issued Regulation No. 327/2011 of 30 March 2011 laying down detailed rules for the application of Directive 2009/125/EC on the specific ecodesign requirements for fans with an electric motor whose input power is between 125W and 500kW (note: 125W – 500,000W) .

Application occurs in two phases, the first from 1 January 2013, the second from 1 January 2015.

For certain particular types of fans (e.g. roof exhaust), the regulations implementing the Directive have not yet been finalized.

S c o p e o f t h e R e g u l a t i o n

The Regulation applies to fans with power input of between 125W and 500kW.

However the following types of fans are excluded from the scope of the Regulation:

- Fans designed for operation in potentially explosive atmospheres (ATEX) (designed and manufactured in accordance with Directive 94/9/EC).- Fans designed exclusively for emergencies in relation to fire safety regulations 89/106/EC (e.g. smoke and heat extractors).- Fans specifically designed to work when the operating temperature of the circulating gas exceeds 100° C.- Fans specifically designed to work with a motor whose ambient operating temperature, if located outside the flow of gas, exceeds 65° C.- Fans specifically designed to work with an average annual temperature of the circulating gas and/or the motor environment, if out of the flow of the gas, less than -40° C.- Fans specifically designed to work in toxic, highly corrosive, flammable environments or in environments with abrasive substances.

Please note: Environments considered as creating abrasive substances and therefore excluded from the scope of the Regulation may be considered the following:• Cement industry• Asphalt industry• Ceramic industry• Cereal milling industry• Glass Industry• Steel Industry • Brick Industry • Wood industry





- Fans for the transport of non-gaseous substances in industrial applications.- CBJET-type fans because the Regulation does not define how to calculate the efficiency of impulse fans.- Fans with a compression ratio R > 1.11- Fans destined for the extra-European market (even if sold to other manufacturers of machinery within the

Community)





Requirements of the Regulation

The Regulation requires that fans of different types, falling within the scope of the Regulation, satisfy specific minimum requirements for energy efficiency and provides calculation rules.

An "efficiency level" N that fans must reach is indicated, which corresponds to the target energy efficiency for a unit with power of 10kW. The regulation also provides rules for calculating the value of the target energy efficiency, called ηTarget, as a function of the power and type of the fan, which in fact represents the minimum value of the target energy efficiency that the fan, inclusive of the components responsible for the transformation of energy (from electrical to aerolic), must reach.

D e f i n i t i o n o f t h e t a r g e t e n e r g y e f f i c i e n c y η T a r g e t

There follow the efficiency levels N for the main types of fans and the consequent value of target energy efficiency target ηTarget.

(NB there are 2 different minimum values to be observed from 2013 and from 2015).

C a l c u l a t i n g t h e e n e r g y e f f i c i e n c y o f t h e f a n η e

Complete fan (without inverter)

The overall efficiency of the fan η e is calculated using the following formula:

η e = P U(S) P e

Where:

- ηe is the overall efficiency

- P U(S) is the aerolic power of the fan

Obtained as the product of: Gas flow rate x Pressure difference x Compression factor, measured at the optimum energy efficiency of the fan.

- P e is the power measured at the ingress of the power supply to the fan motor when this last is operating at optimum energy efficiency





Complete fan (with inverter)

In case of use of variable speed drives, a compensation factor Cc is inserted in the formula for calculating the efficiency. Overall efficiency is calculated according to the following:

η e = (P U(S) P ed) C C

Where;

- P ed is the power measured at the ingress of the power supply to the variable speed drive of the fan when this last is operating at optimum energy efficiency

Where C C is a factor of partial compensation of the load, calculated as follows:

C C = 1 without variable speed drive

C C = 1.04 with variable speed drive and power Ped greater than or equal to 5 kW

C C = P ed< 5 kW, C C = - 0.03 ln(P ed) + 1.088 with variable speed drive and power Ped less than 5 kW

Incomplete fan

This is the case when the fan is supplied with "non-definitive assembly," i.e. when at least the impeller is mounted, but the fan needs one or more components supplied externally to convert electrical energy into aerolic power of the fan.

In this case the overall efficiency of the fan is calculated at optimum energy efficiency of the impeller using the following equation:

η e = η r • η m • η T • Cm • C C

Where:- η r = Efficiency of the impeller- η m = Efficiency of the motor- η T = Efficiency of the traction device- Cm = Compensation factor for Matching of the components = 0.9- C C = Part load compensation factor





L A B E L L I N GThe labelling required by the Regulation must contain:

- Overall efficiency η rounded to the first decimal- Measurement category used to determine the efficiency (A, B, C or D)- Efficiency category (Static or Total)- Efficiency level at optimum energy efficiency- Indication whether the fan requires the use of a variable speed drive and if, in that case, the variable speed

drive is integrated into the fan or must be installed together with the fan

Example of additional labelling:

Option a (without variable speed drive):

η = 55.3% (B, Total) N(2015)=62 N=65 VSD Not Provided

Option b (variable speed drive to be installed):

η = 55.3% (B, Total) N(2015)=62 N=65 VSD Must be installed

Option c (variable speed drive built-in):

η = 55.3% (B, Total) N(2015)=62 N=65 VSD Integrated

Where VSD stands for: Variable Speed Drive.

R E P L A C I N G F A N S A L R E A D Y I N S T A L L E DThe Regulation does not require the adaptation of existing plant and buildings.

In case of replacement of fans installed in plant and buildings before 1 January 2013, the same, until 31 December 2014, may be replaced with identical fans (including those not conforming to the efficiency requirements of the Regulation), as long as they are marked accordingly.





From 1 January 2015, for a replacement, new fans will have to comply with the Regulation.

C B I F A N SMost CBI fans were conceived with design features that place them out of the scope of the Regulation, as they are usually specifically designed for operation at temperatures greater than 100° C, or else for processing toxic and corrosive gases or with abrasive substances typical of industrial environments.

Nevertheless CBI fans were designed with efficiency criteria high enough to satisfy in most cases the efficiency parameters required by the Regulation.

CBI is able to provide where required an adequate selection of machines satisfying the criteria of efficiency required by the Regulation.

Thanks to the selection software specially updated with the parameters required by the Regulation, CBI is able to offer the best solution from the energy point of view.

Where fans are incomplete, typically without a motor, CBI is able to provide the value of optimum energy efficiency of the incomplete fan, as indicated by the Regulation, and to provide all the additional elements for the definition by the customer of the energy efficiency of the complete fan.
