Fire Sprinkler Systems
From Water-Based Systems
Sprinkler systems are used for automatic fire fighting, to protect life and property. The operating principle is straightforward and reliable. It has the largest share of the market for water extinguishing systems. The consistent use of VdS-approved components and careful processing ensures maximum safety and compatibility with international standards.

The Functionality of Sprinkler Systemsy
In the case of sprinkler systems, the pipe networks are equipped with sealed nozzles that open individually when heated and the fire water spray is targeted to the fire source. You can fight or extinguish the fire directly at the source as a result of the resulting cooling effect of water evaporation and the subsequent exclusion of air due to the mist. An extinguishing operation is triggered in case of a temperature rise directly at the sprinkler head. This is achieved by the expansion of a liquid or by the separation of a solder joint. The response sensitivity can be influenced by the design of the sprinkler.
An extensive pipeline network with a closed extinguisher nozzle protects the relevant areas. An adequate water supply is provided from compressed air containers, elevated tanks, mains water, master or intermediate containers with pump systems or various combinations of the systems stated above.
The output of a sprinkler system is designed according to the assignment of fire hazards (Low Hazard LH, Ordinary Hazard OH1-4, High Hazard Production, HHP 1-4 & Storage HHS1-4). The indicators for the plant sizing parameters are protection area, water pressure, effective area and operating time. Depending on the requirements, systems with EFSM (increased water pressure) can be used.
The Extinguishing Principle
In case of fire, one or more sprinklers in the fire area open automatically as a result of the heat. The extinguishing water escapes under pressure and is sprayed on a sprinkler plate; it is then distributed as parabolic drizzle on the fire. In parallel to the opening of the sprinkler an alarm bell and an alarm message will be triggered. Depending on the version of the system, the extinguishing water is first supplied via a compressed air water tank. If the pressure drops, the sprinkler pump is switched on, which pumps the extinguishing water from a water tank.
