As technological leader for ventilation and drive engineering, ebm-papst is in demand as an engineering partner in many industries. With over 15,000 different products, we provide the right solution for just about any challenge.  Our fans and drives are reliable, quiet and highly energy-efficient.
 

 
Adequate air exchange is important for a healthy, comfortable environment and to protect the building structure. However, the energy conservation regulation (EnEV), demands that building envelopes should now be designed with virtually air-impermeable insulation. Window ventilation alone is no longer sufficient to ensure the specified minimum air change rate. Additional ventilation measures are required.
 
Future-proof concepts are ventilation systems of central or decentralized design. With a central residential ventilation system, the unit is installed at a central location such as the cellar and the air is circulated through pipes. Decentralized ventilation systems are installed in specific rooms and can be controlled individually. In both cases it is advisable to use systems featuring heat recovery and demand-based adjustment of the air volume.
 
To suit these requirements, we have developed highly efficient, extremely quiet-running fan solutions with heat recovery, at the same time employing the warm exhaust air to heat the cooler supply air and keep energy losses to a minimum.
 
All ebm-papst fans with GreenTech EC technology already far surpass the efficiency standards likely to come into force from 2020 onwards. We call this “ErP Next – the future of efficiency now”. For our customer’s it is a guarantee of highly efficient, future-proof high-end products conforming to legal requirements.
 
As the legislation relating to ventilation in residential buildings is a complex matter, a brief outline of the two main points is given below:
 
1.       Building air tightness and minimum air change rate. Both these factors are regulated by the applicable building efficiency guidelines. Buildings must be constructed in such a way that the heat transmitting envelope is impermeably insulated while at the same time ensuring the necessary minimum air change rate.
 
2.       Minimum efficiency requirements effective from 1 January 2016, the ecodesign directive (ErP) demands that residential ventilation units satisfy stringent minimum energy efficiency requirements and bear a corresponding energy label. The ecodesign directive currently stipulates the following: Fan regulation with at least three speed levels or, better still, infinitely variable speed control. Bidirectional ventilation units must feature heat recovery. The annual energy demand limit value must be less than or equal to 0 kWh/m². And it is set to become even more drastic: From 1 January 2018 onwards, this specific annual energy demand is required to be below –20 kWh/m². 
 
As pioneers in the development of highly efficient EC fans and innovation experts, we can supply you with just the solution you need – with the best possible efficiency values and guaranteed to conform to the applicable legislation.
 
The highlights at a glance: 
 
ü  Infinitely variable fan control characteristics for a controlled room atmosphere
ü  Ideal fan solutions for central ventilation in new buildings and decentralized ventilation in existing buildings –  Low-noise fan operation for a better quality of life
ü  ebm-papst fans already surpass the minimum efficiency requirements for 2020
ü  Far lower current consumption than comparable fans on the market
ü  Extensive product portfolio of GreenTech EC fans suitable for the DC low-voltage range and single-phase AC (1~ 230).
