Why ebm-papst EC Technology?
EC is easy. Permanent magnet motors running on high voltage direct current (DC) electricity with built in AC to DC conversion allowing them to run direct from single phase or three phase mains supplies. There are several suppliers of such motors so why choose ebm-papst Green Tech products?
EC technology is not new. Not to ebm-papst at least. We developed our first EC compact fan in 1965, 30 years before our competitors started to market their EC products and 15 years before environmental protection was even an issue. In this time we have improved, refined and extended the ebm-papst EC range into the universal, high technology and reliable product which it is today.
This means that ebm-papst EC gives you high performance, silent speed control and long life expectancy in a product which is the same size as the old, power hungry AC products it replaces.
ebm-papst EC products offer you;
-
stepless and infinitely variable speed control
-
fully integrated, mains input power supplies
-
compact motors making them fully interchangeable with AC products for retrofit
-
fully sealed electronics
Having successfully integrated our advanced electronics into the motor, we realised that it would be a waste to only use it for turning the motor. Our large motors have full programmable networking capability for integration with BMS systems or can be individually programmed with a PDA connected via Bluetooth.
Constant volume or constant pressure functionality is easily achieved with the connection of one simple sensor or, in some cases, without any external sensors at all. Silent, infinitely adjustable speed control can be as simple as connecting a potentiometer to the motor. Commissioning becomes simplicity itself.
And finally, but to us most importantly, Green Tech products are not just about high efficiency, energy saving motors. It’s our whole ethos. Every newly developed product has to be economically and ecologically superior to its predecessor. From the efficiency of the motor to the carbon footprint of the factory in which it is made, ebm-papst strives to be green through and through. For example, the average fan factory with a floor area of 13,000 m2 uses around 830,000 kWh per year but we have built new factory for making large EC fans so that it uses only one tenth of this amount. That’s 91% below the standard set by German building regulations.
Why use ebm-papst EC technology? It is more efficient, quieter and more reliable than any other EC product on the market giving better performance and a lower whole life cost. But if for no other reason, then because switching to EC technology will reduce carbon emissions by at least 30%.
