Ziehl-Abegg has introduced its Bionic bio-fan, which the company says reduces CO2, cuts down on noise and electrical consumption, and has better load capacity and temperature resistance. The new fan consists of castor oil-based bio-polyamides. Since the blade geometry incorporates knowledge from bionics, the fan is also quieter and more efficient – and therefore reduces electricity costs and noise emissions in operation. The design is used in refrigeration engineering, in heaters, heating pumps, and for electrical cooling. The fan is also 100% recyclable.
