US testing association certifies EC fans

AMCA, the not-for-profit association which monitors standards and certifications of ventilation technology systems worldwide, has given its certification of the consistent credibility to Ziehl-Abegg for its data on air performance and energy consumption for energy-saving EC fans. At its headquarters in Germany, the company operates one of the world’s largest combined air and hemi-anechoic chamber for fans. “This is a tribute to our long-term commitment to reliability and accuracy of measurement data,” says Vikas Kundra, Managing Director of Ziehl-Abegg India.

The certification of the EC fans is a great contribution to the long awaited certification of the company’s AC products. Both certifications attest 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 composite material. 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.

“When EC fans are installed by our customers they must be able to have total confidence in the quoted measurement values” says Kundra. 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, Germany since 2008,” explains the Managing Director. 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, are quite costly. “But in the interest of providing credible measurement data this is not an area in which we cut corners,” emphasises Kundra.
