74 With Helios even indoor wind surfing is a pleasure using 27 large axial fans to guarantee wind speeds of approximately 7 Beaufort. Impeller diameter 2 m Motor power of each fan 45 kW Total air flow volume 6 million m3/h The axial windmachines are ‘mobile’ and are transported in containers to the different meetings without dismantling. Photo: Dual System Germany Competence i n aerodynamic design Technical ventilation know-how from Helios also is also seen in the most unusual places. The World’s largest artificial tornado, 22 m high, was staged every hour during the EXPO 2000 in the pavilion of the ‘Dual System’. One main fan with an impeller diameter of 2 800 mm located in the roof of the building as well as 40 further fans, arranged in a spiral shape have been used to achieve this special effect.
