Building Fire Suppression Systems

Sprinkler extinguishing systems
Fire safety is especially important for high-rise buildings since fires in buildings with a height of over 9-10 floors usually lead to severe consequences and significant financial losses. This is mostly because the effectiveness of external fire-fighting is reduced due to the height of the building.
Internal fire suppression systems play a leading role in ensuring fire safety in buildings. These include sprinkler spray systems and deluge water systems.
Sprinkler systems are designed for internal firefighting by spraying water. Modern sprinklers do not supply water in a continuous stream, but create a kind of water fog–this mechanism reduces water consumption on the one hand and minimises damage to property on the other. It is also important that when a fire is triggered, only the sprinklers near the source of fire should be activated to reduce the damage. There are essentially three types of installations:
Water
In this type of installation, the entire piping system is constantly filled with water. Such fire suppression systems are used in heated rooms where the temperature never drops below 5°C.
Aerial
Such fire suppression systems involve filling pipelines with water only to the control and start-up site, and they constantly fill the rest of the network with compressed air. Air sprinkler systems are suitable for use in unheated rooms with an average daily temperature of 8°C or lower.
Air-Water
These units combine the operating principles of the first two types and act as water in the warm period, and as air in winter.
Deluge/Drencher Water Systems
Drencher fire suppression systems are used to together extinguish a fire throughout the room, to create water curtains, and water the equipment. Usually they are installed on fire hazardous facilities.
The deluge curtain installation can comprise one or several sections. Each of them is serviced by an independent control and launch unit. The difference between deluge and sprinkler systems is the design of the sprinklers. Sprinklers are equipped with nozzles with thermal elements that melt at a significant increase in temperature, and deluge systems are triggered by an automatic fire alarm.
Foam
Foam is used in protecting chemical and petrochemical industries, warehouses and bases of oil products, and any objects where flammable and combustible liquids are used which could cause the rapid spread of fire.
Gas
Foam is used in protecting chemical and petrochemical industries, warehouses and bases of oil products, and any objects where flammable and combustible liquids are used which could cause the rapid spread of fire.
