TÜV renews certification of high performance ZerAx® axial flow fans

The German technical service corporation TÜV has April 2018 renewed the certification of the Novenco AirBox software for calculation of ZerAx fans from NOVENCO Building & Industry A/S. As with the old certificate, the new certificate covers the ZerAx fan types AZL, AZN and AZW in sizes 355 - 710 with motors from WEG.
The fans sent for test and the AirBox calculation software were tested and found to match each other with an accuracy of B1 according to the TÜV classification system. See page 2 in the certificate.
The ZerAx fans are since the introduction in 2009 unsurpassed and world leading with efficiencies of up to 92%. The technologies and designs are patented all over the world.
