Piercing Nozzle Vehicle

The piercing Extinguisher system consists of a mixture of water and cutting agent (abrasive) being ejected through a special nozzle at high pressure to piercing through all kind of building and construction materials.

The method facilitates combating fire and fire gases from the outside of the fire location. The high pressure of the water results in very high velocity and dispersal of the water into droplets. Once a roof, wall, door, casing, car body or similar construction, has been penetrated the cutting medium is shut off and only water is applied through the thumbnail-size hole in the form of a very finely distributed mist.

As the penetration hole is so small no oxygen is admitted to the fire area, which significantly boosts the firefighting effect. The smaller the opening to the fire area, the more effectively the temperature will be reduced, as the mass of gas will be more easily made inert if the area is completely sealed. The water vapour stays longer in the area and the temperature is reduced accordingly.
