The piston accumulator (1) filled with extinguishant and nitrogen and pressurized to 100-105 bar is connected to a distribution system consisting of: distribution hose(s), distribution pipes and Fogmaker’s patented high pressure water mist nozzles (2).
The detector bottle (3) filled with detector liquid and nitrogen, pressurized to 24 bar is connected to a polymer detector tube (4).
The piston accumulator and the detector bottle are inter-linked via a patented release valve (5) that keeps the piston accumulator closed if the pressure in the detection system is normal. If there is a fire – the detector tube bursts (6), the pressure falls in the detection system and the valve on the piston accumulator releases. As the system deploys, the pressure switch warns the driver through the alarm system (7).
The extinguishant is pressed through the distribution system’s nozzles and a high pressure water mist is spread throughout the protected volume (8). Absorbs heat: 1 liter of high pressure water mist is converted into 1700 liters of water vapor by consuming 540 000 kilocalories. Fogmaker’s water mist contain so small drops that 8000 of them fill out a normal sized water drop.
The fire triangles or combustion triangles or ″fire diamond″ are simple models for understanding the necessary ingredients for most fires. The triangle illustrates the three elements a fire needs to ignite: heat, fuel, and an oxidizing agent (usually oxygen). Fogmaker attacks all three elements.
As high pressure forces the extinguishing fluid through Fogmaker's patented spray nozzles, 8000 tiny droplets are made per every one normal sized droplet. The result is a mist or 'Fog'
1 litre of extinguishing fluid absorbs 540,000 kilocalories and produces 1700 litres of water mist. This creates a choking effect removes the oxygen and cools the temperature significantly. A layer of foaming agent covers the area to prevent re-ignition.
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.
