Water Mist Fire Suppression 610.265.3610
How Water Mist Suppression Works
For a fire to exist, all three elements of the fire triangle must exist. Other systems suppress a fire by attacking one of the three elements of the fire triangle. Only Fogmaker’s water mist system attacks all three parts of the fire triangle.
Oxygen: The basic principle of water mist is using high pressure and special nozzles to create very small droplets of water. The Fogmaker system turns 1 litre of water into 1800 litres of mist. When activated, the high pressure water mist is released into the space where it immediately vaporizes. This vapor displaces enough oxygen to put out the fire.
Heat: The water mist vapor has the added benefit of rapid cooling. It is 540 times more effective than water at reducing the ambient temperature of the compartment. Re-ignition requires high temperatures. Unlike powder systems that quickly disperse, the Fogmaker system actuates approximately one minute although systems can be designed for longer activations.
Fuel: The Fogmaker system includes a low concentration, environmentally friendly AFFF (Aqueous Film Forming Foam) that acts like a powder system to blanket the fuel source.
Other system features:
With its patented piston accumulator, the Fogmaker system is unique in that it can be mounted in any orientation and fully functions regardless of vehicle orientation. Other systems require precise mounting orientations and will not fully engage if the vehicle is not flat on the ground.
The Fogmaker system is fully pneumatic and does not require any electrical connections to function. As such it is not prone to electrical short issues that frequently cause false activations.
The system is available with gauges to allow monitoring of the system pressure. It can be tied into the engine, fan and fuel line functions.
The system is certified for use in temperatures down to -75°F (-50°C).
The gaseous propellant behind the piston remains in the accumulator after system discharge. The fluid and gas in the system can be serviced without removing the extinguisher from the vehicle.
