High Pressure Water Mist Systems: Effective Fire Suppression Technology

Jun 22, 2023 | news

Fire is a significant hazard that can cause extensive damage to property and result in the loss of life. Fire suppression systems are essential for protecting lives and property from fires, and high pressure water mist system is an effective technology for suppressing fires.

High pressure water mist fire suppression systems utilize a finely atomized mist of tiny water droplets to effectively suppress fire. These systems offer several benefits over traditional sprinkler systems:

• Higher efficiency – The large surface area of the mist enables more effective heat absorption per unit volume of water.
• Lower water usage – Only a fraction of the water is required compared to sprinklers for the same level of fire suppression.
• Precision control – The mist can be targeted directly at the fire source with pinpoint accuracy.
• Lesser impact – The mist causes less damage to valuable contents, facilities and electronics.

How High Pressure Water Mist Systems Work?

• Producing a mist of tiny water droplets, typically 15-50 microns in size, at pressures around 40-60 bar.
• Distributing the mist through a network of pipes and nozzles into the protected area.
• The finely atomized mist effectively absorbs heat from the fire through its large surface area, lowering temperatures and oxygen levels to extinguish the flames.

Key Components Of High Pressure Water Mist Systems

• Water source – Usually a tank and fire pump to provide water at high pressure.
• Filter – Traps particles that could clog the mist nozzles.
• Pressure relief valve – Releases excess pressure from the system.
• Actuation – Can be automatic via heat or smoke detectors, or manual pull stations.
• Mist nozzles – Produces the high-pressure water mist.
• Piping – Distributed network of pipes carries the mist throughout the protected area.
• Control valves – Regulate water flow and pressure.
