The intelligent use of water for fire fighting applications The SEM-SAFE® high-pressure water system uses water micro-droplets released through the nozzle into protected areas. An ultra fine mist is formed, with a two-fold extinguishing effect. In addition to cooling the fire, it simultaneously starves the fire of oxygen. The cooling effect also lowers the risk of re-ignition. This makes high-pressure water mist highly effective in the fight against fire and protects against heat damage. SEM-SAFE® in short The SEM-SAFE® system comprises of a high-pressure modular pump unit, section valves, piping and water mist nozzles. With small pipe dimensions, large coverage, minimal water consumption, a compact pump unit and simple design, the SEMSAFE® system is the perfect choice to protect hotel buildings against fire, with reliability and cost-saving in mind. A total of 2,500 SEM-SAFE® high-pressure water mist nozzles have been installed in Alsik, covering OH1, OH3 and OH4 applications such as offices, hotel rooms, restaurants, meeting rooms, atrium and storages. In addition, we have supplied 37 section valves. The entire Alsik hotel is covered by two SEM-SAFE® high-pressure water mist pump units. Fire protection for people and assets The goal is to save lives and limit damage to the equipment and the hotel building. In case of a fire, the SEM-SAFE® system will activate immediately in the areas where a fire is detected. High-pressure water mist has excellent properties in capturing the smoke particles, thus increasing the chances for a safe evacuation of guests and staff. The SEM-SAFE® high-pressure water mist system uses very little water compared to other technologies on the market. In addition, water damage is kept to a minimum. Maintenance-free Danfoss pumps The SEM-SAFE® high-pressure water mist system uses Danfoss PAH high-pressure pumps, which are lubricated by water, making them virtually maintenance-free. Tested and approved system The design of the SEM-SAFE® high-pressure water mist is based on full scale fire tests. The system chosen for the Alsik project has been tested in accordance with CEN/TS 14972 and approved by the Danish Institute of Fire and Security Technology to comply with the European standard for water mist systems prEN 14972 for Ordinary Hazard Groups OH1, OH3 and OH4. Best choice for window cooling The windows of the building go from floor to ceiling, allowing light to project further into the room. The excellent cooling features of the SEM-SAFE® high-pressure water mist technology make it the perfect choice for protecting glass facades. SEM-SAFE® has passed the EN-1364-1 fire resistance test for non-load bearing elements, thus allowing for lighter glass in the building facade. Savings can be obtained by using our technology, as there is no need for expensive fire-resistant glass. “We chose high-pressure water mist as it requires less installation in the building, and thus saves space. For us, the advantage of the SEM-SAFE® high-pressure water mist fire safety system is, that it is a very safe system for people staying in a hotel environment while also incurring limited damage to interiors and technical installations in case of a fire. The system itself has a low water consumption, which releases space in the building that otherwise would have been needed for a big water reservoir, for example. We are very happy with the product and the installation. We will definitely recommend Danfoss Fire Safety to others.” John Knudsen Project Director at Bitten og Mads Clausens Fond Best fire safety solution for high-rise buildings The SEM-SAFE® high-pressure water mist system is the ideal choice for the Alsik high-rise hotel: It does not require large water reservoirs Pipes are thin for added flexibility in installation There is no need for sprinkler units on every floor to prevent pressure loss ® 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.
