Today’s high cost of energy as well as the increasing level of environmental awareness and political measures, spiral the search for modern and more efficient solutions in the field of energy saving.
The environmentally friendly EC+ concept is the result of a close cooperation between Danfoss and NOVENCO and is the latest market response to growing demands for energy saving.

Existing AHUs that get the EC+ upgrade become considerably more energy efficient and move in many cases miles ahead of the competition. This is due to the unmatched EC+ total system efficiencies of up to 85%. The EC+ concept is specifically conceived to increase the efficiencies of HVAC systems and comprises the NOVENCO ZerAx® series of high-efficiency axial fans, high-efficiency IE4 and IE5 permanent magnet (PM) motors and the intelligent and high-efficiency Danfoss VLT® frequency drives.
