SEM-SAFE® high-pressure water mist system In contrast to traditional sprinklers, the SEM-SAFE® high-pressure water mist uses less water and produces a high level of atomization. The water damage in case of a fire situation is therefore kept to a minimum. Water mist has excellent fire suppression properties, including capture of soot particles, strong reduction of radiant heat and rapid lowering of the temperature to acceptable levels. Furthermore, it does not require a large water buffertank or complicated water connections, and there are no major requirements for installation space, structural loads and leak tightness in the building. Isala will have two diesel pumps feeding the system and approximately 10,000 nozzles. The pipes run through a tunnel into shafts leading to the various parts of the building. Risk classification for the Isala project are: • Ordinary Hazard 1 for most areas. • Ordinary Hazard 3 for shopping areas. • Ordinary Hazard 3 pre-action with automatic fire detection for special rooms. • Deluge system with open nozzles and automatic fire detection in atria. Awards In December 2010, D2B (Designed to Build), the construction consortium responsible for realizing the building and the installations, received a gold award for environmental quality with compliments for the continued functioning of the old hospital without disruption, a clean construction site and pride in a building partner with complete trust in continued operations. The new ‘better house’ consists of four connected units, the ‘butterflies’. Flexibility was a high priority. The layout of a ward can be modified relatively easily without affecting the structural skeleton. Another major theme was sustainability. To this end, the Deerns engineering firm designed the technical installations, such as combined heat and power generation (dual source) and motion sensors for lighting. The SEM-SAFE® nozzles are reliable and will keep the water damage to a minimum in case of a fire situation. By using soft colors and natural materials, Isala hospital promoted the well-being of its patience, visitors and employees. ® Danfoss Fire Safety A/S · Middelfartvej 9 · DK-5000 Odense · Denmark Tel. +45 7488 7800 · E-mail firesafety@danfoss.com · www.semsafe.danfoss.com Danfoss Fire Safety A/S can accept no responsibility for possible errors in catalogues, brochures and other printed material.
