New super arena in Sweden is ventilated by new Direjet Vario Fabric Ducting
October 2009
In May 2009, Sweden’s largest multi-purpose arena, Göransson Arena, in Sandviken 200 km north of Stockholm opened. KE Fibertec supplied the air distribution system. The choice fell on the new, flexible Vario nozzle.
In cooperation with Kyl och Ventilation Svante Lundbäck and Grontmij, KE Fibertec AS has supplied the fabric ducting for Sweden's new multiple-purpose arena, Göransson Arena. With 13,000 m2 area under roof, Göransson Arena is unique as to size, design and application possibilitites. The arena cost more than 210 mill. DKK to build and has a capacity of approx. 4,000 spectators during sports matches and a capacity of approx. 10,000 people during other venues.
Apart from bandy that is played on an indoor ice rink of 67 x 111 m the arena is used for a number of different venues such as exhibitions, concerts and indoor rally. For example the next Swedish Eurovision Song Contest is to be helt here, as is the bandy world cup and the Swedish indoor rally championship.
To ensure an optimum air distribution during the many different operational conditions, the contractor chose a combined KE-DireJet® fabric ducting system with 24 mm nozzles and the new adjustable Vario nozzles. The new KE-DireJet Vario fabric ducting with multi-adjustable nozzles is an innovation in textile based ventilation. With the Vario nozzle it is possible to adjust the inlet air direction by 30° in any direction in relation to the standard position. At the same time the nozzle applies for throw lengths of 20-30 metres.
KE Fibertec has supplied totally 697 metres of fabric ducting iin the dimensions Ø900, Ø800 and Ø500 mm for Göransson Arena with a total weight of approx. 1,700 kg inclusive of suspension rails and fabric ducting. With a maximum ridge height of 28.5 m the planning of the installation played a major role in the choice of air distribution system. KE Fibertec supplied all rails in lengths of 2.5 m and the fabric ducts were packad in cartons labelled with tracking number according to drawings. The nozzles were preinstalled and factory-adjusted at the right angle. All in all this meant a much easier and quicker installation compared with a conventional spiroduct system that would weigh approx. 13,700 kg or almost 8 times more than the fabric ducting.
