Extinguishing system with water mist arose from numerous research in order to cover all the needs and requirements of the fire protection requirements, as an alternative to other systems: halon, CO2, sprinklers and presenting many advantages compared to the methods mentioned above. Pure water as fog has the ability to extinguish fires with high calorific value: Fireworks flammable liquids, gases (eg. Hydrocarbon solvents), shots from electronic equipment, cables, wood, paper. It’s the easiest and cheapest extinguishing system using a small amount of water. Fields of application are multiple:
  • ceata apa1Storage of flammable liquids
  • Kitchen Hoods
  • Transformer stations
  • Gas Tanks
  • Galleries cables
  • Technical pubs
  • Engines

Placed in the sewer diversion emission nozzles generate a fine spray of water cone filled with a droplet size of the order of 20 to 200 microns. This type of spray is generally obtained using internal divergence that causes a controlled turbulence before reaching the outlet of the nozzle. Special geometry of these nozzles allow their use at low pressure without requiring a pressurizing agent, resulting in a simplification of the installation in relation to high-pressure systems.

Principles of fog water system:
  • Water droplets creates a heat exchange with the energy produced in the combustion zone, preventing temperature rise. This exchange of energy is proportional to the surface area of ​​the water droplets but not volume. At an equal volume, the more droplets are smaller, the surface energy that is exchanged is greater
  • A side effect is the decrease in oxygen concentration. The droplet of water near the fire outbreak, it will gradually evaporate, expandandu – is 1,600 times, thus removing oxygen
  • Cloud water droplets filter infrared radiation, thus preventing temperature rise
  • Cloud water droplets plays an insulator and prevents heat flow dispersion
  • Radicals that are part of the chain reaction of combustion are absorbed by water droplets, thus interrupting the reaction sequence
