Increased demands on reduced noise and emission of exhaust fumes have lead to enclosed and more insulated engine compartments, higher fuel pressures and increased engine compartment temperatures. Most fires start in the engine compartment. A well-developed fire in an engine compartment often has a very intensive course of event and is impossible to fight with a hand extinguisher. The solution is a permanently installed and fully automatic fire suppression system.
Fogmaker has developed a method that suppresses with the help of three basic mechanisms. High pressure water mist is a far superior fire suppression technique in engine compartments. The high pressure in combination with special nozzles creates microdroplets with an average size of 50 µm. As a comparison, 8000 of these microdroplets are needed to fill a regular water drop of 1 mm in diameter. Large quantities of fuel and hydraulic oil constitute great risks for machines. If they also operate in flammable environments such as the forest industry, recycling or the petrochemical industry flammable material is often accumulated on the engine and can easily ignite. The fires often develop quickly. The water mist protects against fires in engine compartments, hydraulics and built-in brakes. The systems are fully or semi-automatic with hydropneumatic detection.
The advantage of Fogmaker is that the fire suppression system manages heavy voltage variations that can occur during welding work and start assistance and that the system operates independent of power supply. Fogmaker's unique construction means that it will always be completely emptied, regardless of the installation angle or position when released. This is a great advantage since it permits horizontal installation in cramped compartments and this saves space. This is also a decisive safety factor when the extinguisher is installed in a vehicle where there is a risk that the vehicle can land on its side.
Since 1995 Fogmaker International AB has been developing, manufacturing and marketing fire suppression systems for engine compartments with high pressure water mist.
Since 2006 over 15,000 Fogmaker systems have been installed in the UK and Ireland.
The Fogmaker Fire Suppression system has a unique suppressing performance as it both cools down and smothers the fire, at the same time as the foam additive effectively prevent the fire from reigniting.
Fogmaker holds a wide range of certifications and approvals including UNECE R-107, SPCR183-approved by SP, 2016, IATF-16949 and SS-EN ISO 9001:2015.
Once a year the system should be inspected and the functions tested by a certified installer. Normally, this does not take more than an hour. Every five years the suppression system should undergo a revision where the suppression fluids are also exchanged.
The total life span cost of Fogmaker suppression systems is low compared with competing systems. Installation costs often fall below the cost of re-setting deployed alternative systems.
