A complete range of EC fans up to 3 kW for use in a variety of applications, such as building air conditioning, telecommunications, ventilation, and refrigeration, is available. Integrated electronics make the fans easy to operate. These controls make it possible to increase or reduce the fan speed while only using as much energy as necessary, says the company. For large EC fans, a new blade design allows the fans to operate more quietly and consume less energy. The new EC fans have five, not seven, blades. In addition, the blade ends have been optimized with winglets (wider blade ends). The new fans range in size from a blade diameter of 25-40 inches (630-910 mm).
