Danfoss Semco : Water mist
DANFOSS SEMCO HIGH PRESSURE WATER MIST PRINCIPLES
When water is forced through nozzles, at high-pressure, a super-fine mist is formed that has a two-fold extinguishing effect. As well as cooling the fire like a traditional sprinkler, it simultaneously starves the fire of oxygen like gas systems. When the mist comes into contact with flames, it evaporates and expands minimum 1,700 times. The dense vapour created displaces the flames and quickly extinguishes the fire.
The uniqueness of water mist is that it combines the suppression effect of gas and traditional sprinkler systems. As well as removing the oxygen like a gas system, it simultaneously cools the fire like a traditional sprinkler. The cooling effect additionally lowers the risk of re-ignition.
HIGH PRESSURE WATER MIST ADVANTAGES
Minimum use of water
Danfoss Semco nozzles
Small stainless steel pipes
Water is supplied via either pump units or cylinder systems. This covers small systems of just a few nozzles, right up to systems with thousands of nozzles, with or without electrical power.
Intensive research has led to the creation of the world’s lightest and most compact high-pressure pump. Danfoss pumps are multi-axial piston pumps made in corrosion resistant stainless steel. The unique design uses water as a lubricant, eliminating the need for routine servicing and lubricant replacement. The pump is protected by international patents and is widely used in many different segments. The pumps offer up to 95% energy efficiency and very low pulsation, thus reducing noise.
TESTED AND APPROUVED
Danfoss Semco continues to invest heavily in new approvals, as a consequence of new nozzle development as well as the need for adapting to new standards. These approvals for industrial and commercial applications are obtained by testing according to specifications from, for example, FM, UL and ISO, as well as from the European guideline CEN / TS 14972 and approvals from DIFT, VdS and TÜV.
Danfoss Semco was one of the first to obtain approvals in accordance with the European technical guideline TS 14972 for ordinary hazard with a spacing as high as 5.5 meters, and up to 6 m ceiling height for public spaces. Danfoss Semco is also among the firsts to have VdS certificates for ordinary hazard applications, i.e. OH1 and OH2.
