- Ziehl-Abegg is presenting the "MAXvent owlet"
- Medium-pressure axial fans for conventional AC motors and for highly efficient EC drives
- New composite material for fan production receives several awards
The Künzelsau fan manufacturer Ziehl-Abegg has fundamentally improved a fan which is being used, for example, in wind turbine generator systems and in drying plants for foodstuffs. The main benefits of the new product: More air, lower energy consumption and reduced noise emissions. If you rely on the new "MAXvent owlet" you will meet the strict EU energy savings specifications in all cases. "We already by far exceed these regulations for the year 2015" says Chairman of the Board Peter Fenkl. That applies to the energy-saving ECblue motors as well as with traditional AC motors. "In operation, we consume 15 percent less energy than the current products on the market" explains Mr Fenkl.
On account of the convincing efficiency of the "MAXvent owlet", the specifications of the ecodesign directive of the EU (ErP 2015) are not only achieved, they are even significantly exceeded. One reason for being able to achieve this is that the axial fans are made from the newly developed ZAmid composite material. The ZAmid material from Ziehl-Abegg has won multiple Awards during the past months because the composite material has material properties which are similar to steel, but is significantly lighter. Moreover, ZAmid fans can be produced in a one-shot process, without welds or connectors and in bionically optimised three-dimensional moulds. "The 'MAXvent owlet’ together with the ZAmid blades withstands considerably higher speeds" Product Manager Mathieu Forget adds.
The development of this new fan is an international joint project: Working together, engineers from Ziehl-Abegg in France and Germany have established a benchmark in terms of efficiency and performance for medium-pressure fans. "The great benefit is that at Ziehl-Abegg the blade, motor and controller come from one single company and were developed there as a series of matched components" underscores Forget. "No other manufacturer can offer that." This ideal combination of three premium components has resulted in an extremely energy efficient product; this means that means electricity is saved during operation and the payback period is shortened. "The reduced CO2 emission spares the environment" says Forget.
The new generation of the "MAXvent" series is also ideal for emergency diesel power generators in hospitals and airports. The predecessor was the successful MAXvent2, which was also used in water purification units or transformer heat exchangers; the "MAXvent owlet" will once more make a leap forward in the area of energy efficiency.
Ziehl-Abegg is now presenting the new "MAXvent owlet" for the first time. "The product unifies the latest insights from material development and bionics" adds company boss Fenkl. The suffix "owlet" emphasises the bionic approach of the blades. "The serrated blades are modelled on the owl, which plunges down onto its prey extremely quietly during its dive" adds Product Manager Forget. The upshot is, the "MAXvent owlet" can work with increased efficiency and more quietly than its predecessor model and all other comparable fans that are on the market. "We more than halved the noise emissions" clarifies Forget.
Ziehl-Abegg is supplying the "MAXvent owlet" through more than 30 subsidiaries around the world. That means OEM manufacturers are always close to the fan experts from Ziehl-Abegg for modification requirements. The competence centre for the new medium-pressure fans is located in France, which is also where the series production will start. Ziehl-Abegg is launching the "MAXvent owlet" in 13 product sizes, diameters ranging from 310 to 1400 millimetres. The "MAXvent owlet" is ideal for pressures up to 1800 Pascal (static pressure measurement method type A).
