Case story | SEM-SAFE® high-pressure water mist system Alsion in Denmark Large-scale project in Denmark using high-pressure water mist Danfoss Fire Safety A/S The Alsion building was finished on 30 October 2007 and was opened by Her Majesty Queen Margrethe II of Denmark. Alsion was build to create a unique environment in a unique building at a unique location to stimulate local & regional growth. Therefore, a unique fire protection system was chosen: the innovative SEMSAFE® high-pressure mist system from Danfoss. Building description The building covers a gross area of 28,400 m2 and a total of 10 blocks. Each block consists of four levels and one basement. The building has three different applications: University/education of 15,400 m2, concert hall of 1,795 m2 and research park of 5,900 m2. Fire test criteria The system chosen for the Alsion project had to comply with the European standard draft prEN 14972, prepared by the Technical Committee CEN/TC919 “Fixed fire fighting systems”, the secretariat of which is held by BSI. The SEM-SAFE® high-pressure water mist system was thus tested according to the fire test procedures described in this standard. The tests were carried out to prove that an automatic high-pressure water mist system achieved better results than comparable tests carried out with a sprinkler system. After successful testing, the SEM-SAFE® high-pressure water mist system was approved by DIFT (Danish Institute of Fire and Security Technology) to comply with the European standard for water mist system prEN 14972 for Ordinary Hazard Group 1. www.semsafe.danfoss.com
