Water System

The cooling is caused by the spraying of water with a special fog nozzle under high pressure. The oxygen concentration in the air decreases and is replaced by the mist, because the saturation limit has been reached. In addition, the cooling time of the fumigation system inhibits the fire development. This caused less smoke, which can prove life-saving. Also the chronic staff shortages at the Fire Department shows how important this property is. In a fire, the resources be deployed urgently to delete.
The evacuation comes then often too short and also poses a potential risk for the safety of firefighters. Another advantage of a fine spray plant of the type of fog system is located in the lower water consumption. This reduces logistical problems and reduced the dimensions of the fire-fighting equipment. Example: If a sprinkler system is designed so that water needs this 33 liter per square meter, so consumed one, however, Water is only 0.24 Liter.Der reason for this same interpretation in the modified effect of firefighting and indirect delete the spatial effect. And results in the next advantage of this type of fire extinguishing systems.
The fog spreads out in all directions and unfolds its effect up to the smallest detail. A sprinkler system can spray only from top to bottom and reach therefore spatially limited and massive consumption of water used. This permits the use of more sensitive fire alarm systems (BMA), which much earlier to detect smoke and allow a limit, or putting out the fire at an early stage, because when sprinkler systems a massive use of water is given at an already advanced stage of the fire. Smouldering fires or light fires are still not recognized in these stages. This eliminates the still not sprinklers but being insensitive indoors this technique economic, because no high pressure pipe and high pressure pump must be installed. This means also less security and technology requirements. Sensitive buildings, fire a high risk for life, the environment and goods, the effort in relation to the target stands. The insurance companies, who can see an opportunity to reduce damage and reduce the risk premia, thereby increasingly recognise that.
