NESTRO® Lufttechnik GmbH designed, planned, supplied and installed three complete re-circulating wind tunnels for the ‘Nur Alem’ pavilion of EXPO 2017 (10/6 to 10/9/17) in Astana, Kazakhstan. ‘Nur Alem’ is the architectural symbol of the world exhibition and, according to the organizers, the largest spherical building in the world with a diameter of 80 m and a height of 100 m. The NESTRO® wind tunnels allow visitors to the exhibition to experience and feel air-stream speeds of 3, of 5 and of 7 Beaufort in three areas on the sixth floor. Three solar-powered, frequency-controlled, high-performance tube axial fans with blades made of cast aluminum in three separate systems produce the respectively required volume flow rates of 32,400, 55,000 and 80,000 m³/h for this purpose.
