he first W22 high efficiency motors supplied by WEG in Europe - 3 off 200kW machines - are (appropriately) engaged in a ‘green’ process for the production of
sustainable bio-fuels. Te 4-pole 315L frame W22 motors have been supplied to BioWanze in Belgium. Tey are used with inverters in a mill that processes wheat and beet syrup to produce bio-ethanol. With this innovative system, BioWanze intends eventually to provide half the amount of the bio-fuel consumed in Belgium. BioWanze is the first project to produce new generation, bio-ethanol in Europe. Begun in 2009, the plant, at Wanze in Belgium, is capable of producing 758m3
of ethanol per day. Bio-
ethanol is produced from agricultural feedstock – in this case, wheat and beet syrup. Te process is highly efficient - the centrepiece being a biomass boiler with enhanced thermal efficiency - with each element of the process optimised to ensure an overall minimal impact on the environment.

Te requirement for maximised efficiency across the process has resulted in the use of WEG’s new W22 high efficiency motors at the BioWanze facility. Te motors are installed on the cooling tower of the mill at the plant. Tey were supplied by WEG’s Benelux, branch in Belgium, to Hamon Termal Europe, a cooling tower manufacturer, and subcontractors to De Smet Engineering and Contractors, partners of BioWanze in the mill construction project. Te W22 line is a new generation of high efficiency motors; it excels in energy performance due to its ability to reduce motor losses by between 10 per cent and 40 per cent when compared to traditional AC induction motors. Moreover, the W22 units complement their excellent energy efficiency with low levels of noise and vibration in operation. Te W22 motors offer the key advantage that
they already comply with and (in some cases) exceed all the requirements of IEC60034-30, the new harmonised IE (International Efficiency) grading standard for electric motors, which will be standard worldwide from June 2011. Te design that enables them to achieve conformity includes an aerodynamic frame, which increases the air flow and reduces
