Drencher system – definition of drencher system by The Free Dictionary
Upon manual or automatic actuation all nozzles are activated simultaneously, in contrary to sprinkler systems where individual nozzles open one by one only in the fire epicenter. For a building block with 3 or more refuge floors, the water tank capacity will be considered on a case by case basis. This type of system tends to be used in petrol storage, airports, etc. Such system shall be installed in accordance with standards acceptable to the Director of Fire Services.
Fire Sprinkler & Drencher System
They are intended mainly for extinguishing, cooling down, preventing the radiant heat from spreading, cooling down surfaces of buildings, steel structures and technological equipment. Functions Advantages Application References Servis. When the heat from the fire gets to a certain temperature the fire sprinkler heads operate spraying water over the fire. This page of partial functions have not been able completely to support help disabled persons’ software and the instrument.
The water flow rate should be maintained not less than 10 litres per minute per square metreof the external wall openings.

Drencher systems shall be installed on all refuge floors to cover all external wall openings. Drencher system consists of systfm source, pump unit, distribution piping, control fittings, alarm device and special nozzles. Drencher systems are used mainly to protect cable objects, building structures, technology equipment, outdoor oil-cooled transformers and stationary tanks for storing liquefied gases.
There are two types: These systems are used for fire protection of technologies and objects where it is possible to use water as the extinguishing agent. The pipes in this system are filled with compressed air, which are connected to a water main or storage tank with a valve that keeps the water out of the pipes.
A deluge value set shall be installed close to the inlet for the drencher system. The valve will open to allow water to enter the piping system, providing a constant water flow from all sprinklers. The task for drencher water systems is to prevent spreading of fire to other fire compartments and also they are intended to prevent the radiant heat from spreading and to cool down surfaces of buildings, steel structures and technological equipment.
