The SEM-SAFE® water mist system is a unique fire fighting system. By forcing water at a high pressure through nozzles, an extremely fine mist is created.
Water is supplied via a pump unit. The SEM-SAFE® pump unit can supply all water mist applications. This is beneficial because you only need one unit for all applications, and it is easy to add more sections and applications, if needed. In addition, servicing of only one unit is easier and less costly.
For centuries, water has been used as a medium to fight fires by cooling the fire. The breakthrough that water mist represents is to use the same method as traditional sprinklers but to add the effect of converting the water into steam. This means that the cooling effect is up to seven times higher.
If we look at the fire triangle, a fire relies on the presence of three elements in order to survive; oxygen, heat and combustible material. The removal of any one of these elements will extinguish a fire.
A high pressure water mist system goes further: it attacks two elements of the fire triangle: oxygen and heat. This means that water mist combines the suppression effect of gas and traditional sprinkler systems. As well as removing the oxygen like gas system, it simultaneously cools the fire like a traditional sprinkler.
During operation, the high-pressure pump draws water from the tank on unit (a non-pressurised stainless steel tank) and forces it through a non-return valve to a high-pressure manifold. From here, it is distributed to the relevant section(s) via the section valve. A pressure relief valve controls the pump pressure and is designed to return the full pump capacity to the tank on unit.
