Energy, the topic for the future. Efficiency, the demand of our time. Across the globe energy is the topic of the future. Due to the rapid increase in global economic growth and the increasing population, the enormous additional demand for energy presents us with great challenges. By 2030 alone the increase in the demand for energy is expected to rise further by another 40%. The demand for energy burdens our environment and as a consequence the pressure to move over to a more sustainable energy supply is growing. The buzzword of the day. Energy efficiency improvement. The most effective and most...

Small principle. Big effect. Example for a 2-pole motor, 50 Hz: 50 Hz x 60 sec./pole pair. – 5 % slip = 2850 R.P.M. In contrast, the rotating field at the ECmotor becomes brushless by constant electronic switching and adapting to the required operating conditions. Permanent magnets form the magnetic poles, the frequency is thereby not of importance. According to the desired speed the motor winding with a fixed switching frequency is alternately supplied with energy. Thus a continuous, almost linear regulation is possible over the entire speed range (fig. 2). From the use of modern, energy efficient...

EC-motors are brushless direct current motors with shunt characteristic, which were developed specifically for use in ventilation and climate technical systems. Commutation electronics Permanent magnet Lamination stack Longlife ball bearing External rotor motor Aluminium die casting casing

Mixed operation This brings it to the point. 200,00 € energy consumption per year ac Advantages of the EC-technology + Highest motor efficiencies, especially during speed control. + Up to 30 % energy saving at full-load operation and over 50 % during speed control. + Exceeds the requirements of the EuP directive 2015 (Energy using Products). + Amortization within shortest time. + Continuous, almost linear control mode. + Via speed potentiometer simply and economically controllable from 0-100 %. + Integrated regulation electronics (0-10 V signal) saves lossy, expensive solutions like transformer...

Cost minimising and sustainability is a management issue. In the future purchase and operating costs must be calculated closely for fans and controllers in the industry. Clever business companies have already recognised the possible savings which the innovative EC-technology offers. Due to the most efficient operation the payback period for the investment costs for EC-fans is relatively short. The energy consumption is effectively lowered and thus an active contribution to environmental protection is made. The more flexible drive of the EC-technology matches the trend of the increasing networking...

GigaBox and MegaBox EC-centrifugal fans GigaBoxes with energy-saving drive technology are real, multifunctional options that offer almost unlimited flexibility in various applications. I Compact frame construction and assembly-friendly accessories make a variable and thus optimal adaptation possible by simply repositioning the casing panels to the structural conditions. I With five possible discharge directions this gives design flexibilty to suit all site conditions. GigaBox with rain repellent grille (accessories). I All types have integrated crane hooks for easier positioning as standard....
