A unique fan system was created thanks to a newly developed blade design in combination with a high performance fan housing. The ZAplus Next Generation raises the bar again and is the perfect solution for refrigeration units. The combination of motor, impeller, electronics and ZAplus housing means efficiency levels could be enhanced to a whole new level. The successful adaptation of further biomimetic principles to the new FE3owlet blade achieves not only lower operating costs but also improved acoustics.
Our FE3owlet is a globally unique, biomimetic blade design for unrivaled high performance.
With the unprecedented combination of several biomimetic aspects, such as the impressive adaptation of essential findings from the wing shape of nocturnal barn owls - serrated trailing edge, profiled, sickle-shaped wing - and the new leading edge inspired by biomimetic principles. ZIEHL-ABEGG engineers developed a completely new, biomimetic wing design with unbeatable impeller performance.
The Next Generation of ZAplus fan housing allows an optimal air flow. The smart ventilation system offers significantly higher levels of performance data and acoustics, which is also reflected in considerable cost savings per unit. With integrated guide vanes as motor suspension and a short diffuser on the pressure side, ZAplus noticeably improves its performance data and acoustics. The robust multi-diffusor leads to a major increase in performance. The brand new guide vane with revolutionary biomimetic fine air dividing technology for exceptional reduced acoustic values with up to 4dB lower noise level.
The well-known ECblue motor technology plays it part as well in this fan system. ECblue motors fulfil all relevant EU energy efficiency directives. The motor efficiency allows declaration of the IE5 class (Super Premium Efficiency).
The interaction of biomimetic blade design, the integrated guide vane with biomimetic fine air dividing technology and the premium ECblue motor makes the ZAplus Next Generation to the best fan system in the market.
Why is this all so important? More and more refrigeration equipment is now found in built up areas so noise is always going to play its part, the new ZA plus 2nd gen helps achieve much lower noise levels than ever seen before. Not only does it do this but it can also give more air, so in the world of increasing temperatures its important that the refrigeration equipment is up for the task, thirdly its got to do all this using less power! ZA plus 2nd gen meets all of these challenges.
The next rounds of ERP or also known as Regulation EU2024/1834 comes into force in July 2026 which means the levels of efficiency in fan systems is pushed again even further and conventional AC fans will fail to achieve the efficiency levels required. The good thing is the ZA plus 2nd gen fans not only achieve the levels required it sets the bench mark for levels that can be achieved.
