We launched the world’s first EC/DC compact fan on not least to live up to our own expectations. the market right back in 1965 – 30 years before any other manufacturer. And so GreenTech EC technology made by ebm-papst is the Motors with a built-in saving effect. outstanding product of a consistent efficiency strategy – in other The most significant advantage of fans and motors employing words it is the most authentic EC technology.

This means not Without doubt the development and advancement of EC technology only better utilisation of primary energy, but also reduced heat loss represented one of our most significant challenges. Today, the largest and hence a longer service life. range of EC fans and motors in the world is evidence of our success.

Whether we are talking about ventilation, air conditioning, refrigeration, information technology, heating systems, building systems, industrial automation, automotive engineering or telecommunications – there is a need to save as much energy as possible wherever motors are employed in drive systems or for ventilation. GreenTech EC technology leads by example: All our EC fans already surpass the requirements of the ErP directive for 2015. And that’s not just talk, but a proven fact! Example: Energy savings in the air conditioning sector. And here’s another fact: Even at varying speeds, GreenTech EC fans maintain their extremely high efficiency levels, whereas there is a sharp drop in the already inferior efficiency of AC motors. In the case of condensers/evaporators operating with our EC fans for example, energy savings of more than 10 % can be achieved even just at nominal speed. The relative and absolute savings become yet more apparent with infinitely variable control. As compared to GreenTech EC technology, conventional phase control may require more than [W] [W] twice as much energy depending on the operating point. 1 800 1 600 AC with phase-angle control AC with transformer AC with frequency inverter ebm-papst EC 1 400 +650 W +118 % 1 200 1 000 800 +200 W +36 % 600 550 W 400 Pe Pe 200 qV 7 000 Pe = Input power 6 9 000 q V = Air flow 11 000 13 000 15 000 17 000 [m3/h] Power consumption for various control methods 29 % savings E. g. A3G800 axial fan. A heat exchanger operates with 6 fans. Given an average utilisation rate of 75 %, there is potential for saving more than 24 MWh per year. That corresponds to roughly 14.4 t of CO2 and represents a saving of 2,814 euro*. 67 % savings E. g. W1G200 axial fan. 40 fans operate in refrigerated display cases in a small supermarket. On account of the lower level of heat generated by the energy-saving motor, the operating time is 30 % shorter. This translates into a potential annual saving of more than 9.4 MWh and 5.6 t of CO2. Cost saving: 1,080 euro*. 22 % savings E. g. R3G500 centrifugal fan. 6 precision air conditioning units, each equipped with 3 GreenTech EC fans, operate in the IT rooms of a computer centre. Given a 100 % duty cycle it is possible to save up to 50 MWh of electricity. That corresponds to around 30 t of CO2 and 5,898 euro* per year. * Based on CO2 emissions of 600 kg/MWh (German energy mix) and 11.69 cents/kWh, average price paid by industry for electricity in Germany (as at: January 2010, source: VEA, BDEW). 7 Higher Tech: GreenTech EC technology surpasses standards. Natural resources do not last for ever, so certain materials are GreenTech EC technology is the right answer for motors as well. becoming ever scarcer and more expensive. Consequently there is The situation for electric motors is basically the same as for fans. a growing demand for energy-saving products – not just on the part Since June 2011 they have been required by the EU ErP executive of consumers, but also in the light of new legislation to limit energy order no. 2009/640/EC to at least satisfy efficiency class IE2.

This affects pass the required efficiency standard. many different sectors, from refrigeration and air conditioning systems right through to machinery and IT applications. New limit values highlight the limitations of conventional fans. Starting in 2013 and with effect from 2015, two-stage implementation of the ErP directive will enforce more stringent efficiency requirements for fans in the power range between 125 W and 500 kW. The corresponding minimum efficiency values for the various types of fan are stipulated in the EU directive no. 327/2011. The future belongs to GreenTech EC technology. In the light of these developments, the strengths of the innovative GreenTech EC technology created by ebm-papst for electrically driven fans really come to the fore. In contrast to fans employing AC tech nology, GreenTech EC motors from ebm-papst achieve efficiency levels in excess of 90 per cent, thus permitting substantial energy savings as compared to conventional AC designs. Added to this, the speed of GreenTech EC fans can be regulated to adapt the air volume to the specific requirements. This has the positive effect of considerably reducing energy consumption still further. 8 Top performance under all conditions: Guaranteed! Just one example of flexible fan operation: Air conditioning and refrigeration in a supermarket. This application demands full speed and capacity in summer at peak load, reduced capacity in the winter months and q uiet running at low speed during the night. GreenTech EC technology from ebm-papst is the ideal answer under these theoretical but nonetheless realistic conditions. Intelligent control functions make it possible to quite simply adapt air conditioning and cooling to all the requirements of manufacturers, operators, consumers and Example: Performance comparison for condensers/evaporators.

The fans remaining in operation continue to run at full speed. The energy saving potential with GreenTech as compared to AC fans is quite considerable – as shown by the graphs below.

All fans thus remain in Example: You can count on considerable savings potential. operation – and far less power is consumed as a result.

But that’s not all.

On/off operation: To adapt the air performance to differing cooling requirements, it is still standard practice to switch individual AC fans off and on. Modulating operation: All devices and fans remain in operation. Optimum cooling performance is achieved by continuously regulating the speed of all fans.

The ErP directive for 2015 quite clearly shows: EC technology from ebm-papst is years ahead of its time. Not surprisingly, as we were one of the first technology companies to recognise the potential of electronic commutation and systematically promote its advancement. To stop now and rest on our laurels would not do justice to our claim to be the leading innovative company in the field of fans and drive systems. And so we continue to pursue our research and development work. We do not just concentrate on the actual motor, but rather look at every product as a whole with a view to exploiting all possible potential for increasing efficiency – whether this is to be found in materials, electronic control or aerodynamics. A few examples: We have not finished yet. The future belongs to biomaterials. Without doubt: Our EC technology forms the hub of GreenTech around Increasing efficiency whilst conserving resources – the comprehen- which everything revolves. And we intend to keep it that way. Even so sive GreenTech approach starts with the development and production there is no let-up in our constant research and development activities – of our motors and fans. We are already in the process of developing in all areas of fan and drive technology.
