GreenTech EC technology:
The original.
EC technology can mean a lot of different things. These days the term
is broadly used to refer to a variety of drive concepts such as PM
the market right back in 1965 30 years before any other manufacturer. And so GreenTech EC technology made by ebm-papst is the
only better utilisation of primary energy, but also reduced heat loss

commutation strategy and motor design. The tangible result for cus-
many of our EC fans are exactly the same as those of their AC equiv-
alents.
And this is not just the case for new applications. Changing from AC
of the ErP directive for 2015. And thats not just talk, but a proven fact!
Example: Energy savings in the air conditioning sector.
And heres 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/evaporatorsoperating 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 c ompared to GreenTech
EC technology, conventional phase control may require more than

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 p rice
paid by industry for electricity in Germany (as at: January 2010, source: VEA, BDEW).
Higher Tech:
GreenTech EC technology surpasses standards.
Natural resources do not last for ever, so certain materials are
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

GreenTech innovations:
Thats where the future lies!
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:
replacing certain oil-based plastics in the future. Good for the environment and a good selling point.

Numerous different bus systems can be employed to link the coordinating and automation levels. The process data of the higher-ranking
coordinating level, e.g. a BACnet system, are made available by way
of the bus systems.
The field level is where the actual actuators operate such a s the
ebm-papst GreenTech EC fans and motors. There are also numerous
sensors for measuring the ambient temperature or the pressure in the
coolant pipes for example.
