Water mist
What is a Water Mist system?
Water mist as an effective means of fire suppression system operates on the principle of cooling the fuel/heat mix in an active fire.
There are two water mist systems available; High Pressure and Low Pressure.
The benefits
With any fire alarm activation in public places or buildings, we automatically think of the traditional water sprinkler system. But the traditional sprinkler system as an effective method of fire suppression has moved on.
The High Pressure Water Mist system is comprised of water and pressurized nitrogen contained within pressurised cylinders and discharged via high pressure storage pumps through a small bore stainless steel pipe work array and high pressure discharge nozzles.
This system uses minimal volumes of water.
The Low Pressure Water Mist system is typically comprised of a series of pumps and storage tanks.
Tending to use more water than the high pressure system, this option does use less water than traditional sprinkler systems.
Due to the reduced pressure, the associated pipe work can be of different source and integrity, ranging from copper pipe to specialist plastic piping.
Suitable environments
- Diesel Generators
- Food Processing
- Hotels
- Data Centres
- Hospitals
- Care Homes
Considerations
The process of combustion has already to be under way for
this system to be operational and effective. The inherent nature of the system
means that it is unsuitable in environments of risk involving electrical
equipment or sensitive materials.
