How Does it Work?

Impulse fire extinguishing technology discharges the extinguishing agent in a matter of milliseconds at a very high velocity right into the seat of the fire.

25 bars of air pressure in the pressure chamber provide the high discharge velocity; the extinguishing agent – usually plain water – is pressurized with 6 bars into the water chamber.

The extinguishing agent is released by a high speed valve, which lays between the two chambers; the valve opens for only 20/1000 of a second.

The nozzle made of stainless steel consists of a power chamber, a high speed valve, a pistol grip with release mechanism and a water/agent chamber. The power source is 25 bar compressed air.
When the valve opens, the compressed air forces the agent out of the nozzle at high velocity within milliseconds. The fire extinguishing agent is discharged with high momentum, high penetration effect and high fire cooling power.

Air resistance acting on the water stream breaks the water droplets down and reduces the normal mean droplet size from about 700 microns to an average of 100 microns. So the cooling surface of one liter of water is increased from the normal 5,8 sqm to 60 sqm, thus reducing the temperature in confined rooms from a deadly 1000°C to 40°C within seconds.

The smaller the size of the water droplets, the greater their absorption capacity; the higher the droplet velocity, the greater the amount of water that reaches the base of the fire.
Only a small amount of water has to be moved to the site of the fire for an effective initial attack. This makes for the high mobility of use.
