German TÜV SÜD renews certification of the NOVENCO® ZerAx® fans
The German technical service corporation TÜV SÜD in Munich has September 2020 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 one 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 fan efficiencies of up to 92%. The technologies and designs of the fans are patented all over the world.
