New radial fan developed with bionic profile blades
Germany, Künzelsau, Baden-Württemberg: The fan manufacturer Ziehl-Abegg has developed a new generation of radial fans drawing on the knowledge gained from nature, and allowing for energy savings of up to ten percent.
Germany, Künzelsau, Baden-Württemberg: The fan manufacturer Ziehl-Abegg has developed a new generation of radial fans drawing on the knowledge gained from nature, which allows for energy savings of up to ten percent, according to the manufacturer.
The company applied the knowledge of bionics gained from the study of humpback whales to the new ZAbluefin radial fan, enabling peak efficiency to be achieved, the manufacturer said in a press release.
“The characteristic features of excessive turbulence are high flow losses and noise,” says Dr. Walter Angelis, Technical Manager for Ventilation Systems at Ziehl-Abegg.
Over millennia the humpback whale has optimised the design of its fins so that a whale weighing 25 to 30 tons can swim very quickly and with great agility. “We have recreated this on the leading edge of the fan blade and implemented it as an undulating profile,” explains Angelis.
According to the manufacturer, a bionic profile ensures higher efficiency and lower noise. With the bionic profile blades, there are no gaps into which dirt or condensation can penetrate, providing additional strength and optimization of the weight.
