Ziehl-Abegg data credibility endorsed by AMCA

AMCA, the not-for-profit association which monitors standards and certifications of ventilation technology systems worldwide, has given its endorsement of the consistent credibility of German manufacturer Ziehl-Abegg's data on air performance and energy consumption for energy-saving EC fans.

At its headquarters in Germany, Ziehl-Abegg operates the world’s largest combined test chamber for fans.

“This is a tribute to our long-term commitment to the reliability and accuracy of measurement data,” said Ziehl-Abegg’s chief executive, Peter Fenkl.

The certification of the EC fans comes as a counterpart to the long-awarded certification of the company’s AC products, with both certifications serving as a testament to Ziehl-Abegg’s position as a technological leader in aerodynamic and energy-saving fans.

With a high level of vertical integration in manufacturing, the company produces fans made of steel, aluminium and plastic. The modern energy-saving fans are powered by external rotor motors with integrated control electronics; the external rotor technology was developed by the founder of the company, Emil Ziehl.

Mr Fenkl explained: “When EC fans are installed by our customers they must be able to have total confidence in the quoted measurement values. In many installation situations the individual measurement values for EC motor and ventilator can no longer be measured as they become lost in the overall system. This is why we have been operating the world's largest combined measurement and test chamber for fans in Künzelsau since 2008.”

State-of-the-art, high-precision measuring instruments, plus regular training for employees combined with regular inspections by external organisations such as AMCA or TÜV, can be quite costly, but Mr Fenkl emphasises: “In the interest of providing credible measurement data this is not an area in which we cut corners.”

Mirco Herrmann, managing director of Ziehl-Abegg in the USA, is delighted with the endorsement of the measurement precision awarded to his parent company as the certification also applies to EC products made in the US. He explains: “This means we can promote this new certification along with the already existing certification for our AC products in the USA where everyone is familiar with AMCA. We have maintained long-standing relationships with our customers built on trust – this is now underlined by the AMCA certification.”
