The construction opens within twenty minutes and then has an opening of 120m x 85m, i.e. the same size as the pitch of the stadium. elnic provided several air machine systems to support the air inside the new stadium roof and connected them on site.
The closed roof is an air cushion roof and must be continuously supplied with air. Before the roof is opened, the elnic eluft machines draw the air out of the pillows, so the membrane can be pulled together more quickly.
All units are made for 60Hz network and can be delivered with UL certificate.
In order to test the design, a prototype was constructed in the United States, a strip of the oval roof. This mock-up was set up near Seattle to test whether the design will work. The textile roof has to emerge and then inflate. Then emptied again bydrawing out the air. The membranes are again retracted and stowed away in the middle of the roof. Wind and rain influences were examined here. elnic developed and manufactured the air machines for this roof. They control the inflation, deflationand the conditioning of the pillow.
