EU-Regulation 327/2011 for Fans
Thanks to the ErP Directive, the energy-saving potential of numerous energy-related products is being investigated and minimum requirements specified with regard to their energy-efficiency. Eventually, in June 2010, mandatory limit values for fans were specified.
The directive defines a fan to be the unit consisting of nozzle, impeller and motor, as well as any control electronics present (see Fig. 1). The aim is to categorise products brought onto the European market with ageneral minimum efficiency specification for fans. The first stage of the minimum efficiency specifications for fans became effective on 01.01.2013.
More stringent requirements from 01.01.2015
The second stage of Regulation 327/2011 came into effect on 01.01.2015. Then the minimum efficiency requirements will be increased again, compared with the limits from 2013. This means that affected products which do not meet the minimum efficiency requirements can no longer be brought on to the European market from 01.01.2015. This only applies to so called motorized impellers.
Introduction of the Regulation 1253/2014 and 1254/2014
1st of January 2016 the next step of the ErPdiretive comes into force. It rules ventilation units which is intended to to replace utilised air by outdoor air in a building or a part of a building. Included are roof fans, duct fans, residential ventilation units and modular air handling units. These ventilation units have to fulfil a minimum efficiency and need to have at least a multispeed control which is under the response of the installer.Systemair supports all customers with a wide range of controls.
Excluded from this regulation are still ventilation units used for security functions (Ex- and smoke extract) aswell as units for processes like extract of agressive or high temperature mediums.
Definition of “placing on the market“
After the indroduction of the regulations 1253/2014 and1254/2014 at the 1st of January 2016 it is only allowed to sell ventilation units within the EU which meets the new requirements.
Due to high lead times and inventory levels, fan manufacturers will not be able to get through all their stock by the deadline. The legal definition states that the ventilation unit is already on the market once it leaves the factory. Ventilation units which are stocked at the customer before the valuation date are allowed to be installed and set into service afterwards.
Which fans are affected?
Fans of all types of construction with an electrical input power above 30 W are affected by the Directive. For manufacturers such as Systemair, this means that some models with affected motor-impeller units need to be changed and adapted. Systemair will continue to be able to offer you complete model series of the different variants in the future. Fans which are already equipped with EC motors today already meet the requirements.
Which fans are not affected?
Fans with the purpose of providing protection and which are outside certain temperature ranges are not affected. This includes: •Single stage smoke extraction fans, as long as these are not used for daily ventilation on demand •Explosion-protected fans •Fans for the extraction of aggressive media •Fans for transported media temperatures above 100°C •Fans for ambient temperatures above 65 °C
During the course of the introduction of the Directives,many manufacturers will also improve these motors without being legally required to do so.
There is also a Regulation for motors (“MotorDirective”) – what’s the difference?
The ErP Implementation Regulation No. 640/2009/EC specifies the efficiency of electric motors or, more specifically, IECstandard motors. This regulation refers only to the motor. Since 01.01.2015 only asynchronous motors with an efficiency class of at least IE2 (up to and including 5,5 kW) and from 7,5 kW with efficiency class IE3 may be brought onto the market. The use of IE2 is allowed at Motors above 7,5 kW if they are used with a speed control (e.g.Frequency converter).
IEC standard motors (from 0.75 to 375 kW) shall fulfill efficiency class IE3 or IE2+FU from January 1, 2017.
