OERTZEN HDL - The compact revolution
Extremely short fire-extinguishing times by micro-spraying of water. The procedure of high pressure fire-fighting is based on the micro-atomizing of water. Producing finest water drops consequently will result in a large water surface. Hence the cooling effect of the water is best used (energy cut-off). At the same time the concentration of oxygen is reduced by the development of water steam resp. the supply of oxygen is blocked.
The mode of effect
The water flow raised to a pressure of up to 250 bar causes the water to exit the spray nozzle of the spray pistol with high speed. Hence the water mist also arrives at hard-to-reach seats of fire, e. g. in roof frameworks, wall panellings or false ceilings. In short time the fire loses a great amount of energy because of the vaporization of the water. In turn, the amount of oxygen in the fire blaze sinks under critical limits leading to the quench of the already weakened fire. It is just this double effect which makes the fire-extinguishing procedure with high pressure so effective.
