Drenchers Will Improve Your Fire Protection System

Drenching Fire Protection

Drenchers are a system of water heads that are used for the fire protection. In contrast to sprinklers which are found internally, drenchers are normally found on the exterior of a building to protect against a fire from a neighbouring building.
They tend to be positioned on roofs and over windows and external openings.
They are also used extensively in tunnels and depots to protect steel reinforcement and equipment.

Why install a drencher?

One of the main reasons to install a fire drencher system is to control water usage and the resulting costs. Fire sprinkler systems are expensive, especially when they are installed in older buildings.
The cost of installation is typically between $8,000 and $10,000 per acre. Commercially rated fire sprinklers can reduce water usage by as much as 90 percent, but the initial cost of the system prevents many companies from installing them until they are required to do so by law.
Installation costs can range from $400 per square foot to more than $1,000 per square foot for older buildings.
Fire drench systems, on the other hand, cost around $0.75 per square foot. They are relatively inexpensive because they use water only when necessary and don’t require any additional structural changes to the building’s infrastructure or walls.
They also do not damage or corrode wiring or plumbing like fire sprinklers may if left unused for long periods of time.

The three main types of drenchers are:

There are basically three types of drenchers: roof drenchers, wall or curtain drenchers and window drenchers.
Roof drenchers are positioned on the roof ridge and throw a curtain of water upwards.
Wall or curtain drenchers throw a curtain of water over openings or portions of a building most likely to admit fire.
Window drenchers position horizontally level with the top of a window so as to protect the opening.

A drencher system consists of the follows components:

A fire drencher system is a special type of fire protection system which is used to control fires, especially in industrial and commercial areas where the possibility of explosion is high. It uses water as the extinguishing medium and aims at controlling the fire in its incipient stage itself. Fire drenchers can be installed both indoors as well as outdoors.

A fire drencher system is composed of the following components:-

Water source
Pump unit
Distribution piping
Control fittings
Alarm device
Special nozzles or water heads
The water heads are like those of sprinklers and may be sealed or unsealed. (Unsealed systems are activated by manually turning on a main valve in the event of a fire, while sealed systems are activated automatically)

Advantages of using a drencher rather than the sprinklers

The fire drencher is a more cost effective and better alternative to the fire sprinklers. The fire drencher is used for large spaces as well as for small spaces.
They are used to detect and put out fires in warehouses, factories, offices and homes.

The main advantages of this type of fire fighting system are: -Affordable -Easy to install -Simple maintenance.
The fire drencher is a very convenient way to fight fire because it can be installed easily in places where the water pipes cannot be laid. It can also be placed at high points so that it can reach all parts of the building.

Fire drenchers are an effective, inexpensive, fire protection method that can be installed on buildings quickly. They’re an easy way to protect a building from fires, and if they had been used in the Grenfell Tower, many lives would have been saved. There are lots of other ways to prevent a fire like that from happening again, but fire drenchers are some of the cheapest and easiest ways to do that. And they’re not just for residential buildings either—they can be used in office buildings as well.
Another advantage of fire drench systems is that they are not dependent on electricity or water supply to function properly. If a fire occurs and there is no water available at all due to an electrical failure or a broken pipe, the drench system will still work as designed.

In Conclusion

Drenchers are a critical component in the protection of an occupied or unoccupied premises or structure against fire.
The range of applications for these water heads are widely varying, including tunnels and depots, warehouses with high window spaces, roofs, open-plan office buildings, computer rooms, multiple storey buildings and external openings to name just a few.
