The German fan and electric drive manufacturer Ziehl-Abegg puts the spotlight on bionics: This time a marine mammal is the idea behind a new fan development. “My colleagues have clearly underlined their position at the forefront of bionics and as leaders in fan technology,” emphasises Peter Fenkl, chief executive officer at Ziehl-Abegg SE. The innovative fan ZAbluefin increases efficiency by up to 15 per cent. When it comes to reducing energy consumption in the production process, plant managers of industrial companies are professionals. In this context, they look at benchmarks and invest on a targeted basis with the aim of achieving a rapid return on investment. However, ancillary costs not directly associated with production are often viewed as unalterable and are tolerated as a permanent annoyance.
