Water Extinguishing Systems
There is a range of systems available on the market for water extinguishing systems. These systems provide effective means of fighting fires depending on the particular application.
The following systems are available:
- Sprinkler systems
- Spray-water systems
- Mist extinguishing systems
The sprinkler system is the most widespread type of system
Sprinkler systems detect,report and extinguish fires in very short periods of time .The main characteristic of a sprinkler system is the controlled and metered use of water over a limited local area. It can be deployed precisely where it is needed. And only there.
International statistics show sprinkler systems have been successful in 98% of all cases over the past 15 years.More than 70% of these fires are extinguished by max. 4 sprinklers.
Important: The water damage incurred through the use of sprinkler systems deployed in extinguishing the fire is covered by insurance.
There are basically two types of sprinkler system:
wet systems and dry systems
Wet systems are alway used if a non-freezing environment is guaranteed in all areas proteced by the sprinkler system. When not in operation, the wet system is completely filled with water and is under a system pressure of max. 10 bar. After a sprinkler has been opened, water to extinguish the fire comes out immediately.
Dry systems are used where there is risk of freezing in the pipework (e.g. underground parking lots). The network of pipes behind the alarm valve station is filled with compressed air has to be expelled from the system before the water for extinguishing the firecan come out of the open sprinklers. Dry systems therefore react to an outbreak ot fire with a certain delay.
Both types of system can also be used to protect against special risks such as liquid storage tanks and PE/PP storage.
