All AxZent fans have new optimized and high efficient HD impellers with backward curved blades, manufactured from aluminium. The fans are equipped with IEC standard motors outside the air stream for all 400V three phase motors from 0.75 kW. Optimum motor protection by cold conductors to be connected to an external motor protection device. The long casing is manufactured from pre-galvanized steel and has spun flanges according Eurovent 1/2, for direct installation in duct systems.
Please note: Speed control by voltage, i.e. voltage transformers, is not possible!
In accordance with Commission Regulation (EC) no 640/2009 of the European Parliament - eco-design requirements for electric motors - the new international efficiency classes are binding as of 16 June 2011. These guidelines defined by CEMEP and EPACT are regarded as international standard for energy-saving high-efficiency motors for frequencies of 50 or 60 Hz and make the use of IE3 motors mandatory.
With this new and more efficient technology we offer our customers many advantages such as environmentally friendly operation, reduced energy consumption and hence lower emissions. IE3 motors have a higher efficiency even in part load operation and allow optimum adjustment to the operating point. In addition, the IE3 motors generate less noise and develop less heat, which has a positive influence on the efficiency and the cooling requirement of the motor. Please note: IE3 motors cannot be speed controlled by voltage, i.e. voltage transformers.
