ABB and Novenco offer a modular axial fan package claiming up to 85% system efficiency

The useful part

Swiss motor and drive manufacturer ABB says it is collaborating with Danish fan company Novenco, to improve system-level energy efficiency across axial fan applications. The first result of that is a complete axial fan package combining Novenco's ZerAx fan with ABB's IE5 permanent magnet motor and variable speed drive. It claims a system efficiency of up to 85% in a typical air handling unit installation, outperforming EC and belt-driven fan alternatives.

What to take from it

Collaboration creates high efficiency fan package. Novenco's ZerAx axial fan is said to achieve up to 92% aerodynamic efficiency at the impeller, thanks to an optimised blade design and a hub reminiscent of a jet engine. Unlike EC fans, the modular architecture of the ZerAx package – with fan, motor, and VSD as separate components – means each element can be independently upgraded, retrofitted, or replaced as needed.
