More than 8,000 all-terrain, mine-resistant, ambush protected vehicles (M-ATV) are protected by automatically activated aerosol fire extinguishing systems. These vehicles are deployed in various combat zones.
Vehicle durability through battlefield experiences is one of the primary objectives. The fire detection and suppression systems are installed in various parts of the vehicles to protect the engine. The system is specifically tailored to the vehicle’s interior/exterior shape and volume and contains a specific fire extinguishing agent designed to extinguish the fire of a predicted scenario in the protected area.
The system addresses slow growth and rapidly developing fuel fires generated by various explosive effects. It extinguishes petroleum, oil, and lubricant fires before crew members are incapacitated or significant vehicle damage occurs.
System consists of:
• Rugged, programmable fire heat detection and release system.
• Lightweight aerosol fire suppression
The aerosol generators can be activated either manually or automatically from a control device. Upon activation, aerosol generators produce an exceptionally effective, ultra-fine, potassium based aerosol. The generators have a lifespan of ten years.
Unlike other fire extinguishing systems, aerosol generators are cost effective to install and maintain due to the elimination of the cost, space, and weight of pressure vessels, piping, and other expensive installation considerations associated with other extinguishing systems.
On an agent weight spectrum, aerosol is ten times more effective than gaseous agent alternatives. The aerosol efficiency is a function of its patented design, aerosol composition, and ultra-fine particle size. Fire suppression is rapidly achieved through interference between the ultra-fine particulate and the flame’s free radicals; this interference terminates fire propagation.

Sample Installation of Stat-X System:
Since the vehicle is deployed in the battlefield, it is subject to explosions, requiring the fire extinguishing system for this application to be rugged and properly secured. The Stat-X system is secured with heavy duty brackets and tested for MIL standards to withstand the vibrations caused by explosions.
Engine compartment fire suppression system provides the following performance:
• Complete detection coverage by means of rugged overheat detector, which can withstand dirt and is easy to install in areas such as under the engine, batteries, auxiliary power unit, turret floor areas, etc.
• Two levels of operation: overheating will activate an alarm and fire will automatically activate the extinguishing system
• Release panel should have built in test and monitoring indication
• Operational under all possible vehicular working conditions
• Shut downs the engine before agent discharge.
Overassen AS produces the large snow blowers in Gjovik, Norway.
The end user was looking for a reliable, well documented, and approved fire extinguishing system that could fit in the engine compartment.
Stat-X® fire suppression system became the answer to the challenge because we have the Swedish bus approval, which felt comfortable and “close to home”. Further our customer needed a distributor that could support and install the system. The Stat-X light weight and pressure-free system showed to be attractive.
Snow plowing and blowing vehicles are used to clear the snow from runways in airports, from railway tracks, and from the roads during winters in region with heavy snowfall.
These vehicles are big structures which house engines, batteries, electrical wiring, and fuel tanks inside them to perform the intended task.
The traditional method of fighting fires in this type of equipment is a handheld extinguisher, which is not effective for these kinds of applications because handheld extinguishers are not automatic, the delay gives time for the fire to spread and sometimes makes it harder to extinguish.
Also, the engine closure and other areas in these vehicles is small and restrict easy manual access which makes it difficult to install a conventional fire suppression system.
Causes of fire in these vehicles:
Nearly one out of seven fires involve vehicles in USA*, fires in these vehicles are due to:
Most of these fires belong to Class A, Class B, and Class C fires which are initiated by the above causes.
For example: an oil, hydraulic fluid, or a fuel leak cause liquids to come into contact with areas of the vehicle which are hot enough to ignite them, this leakage can be due to a poor maintenance. The fire resulting due to this cause falls into Class B category.
Scope of Stat-X Fire Suppression for this Application:
Stat-X has been listed by Underwriter’s Laboratory (UL) for Class A, Class B and Class C fires as a suppression technology for fighting these fires by using a total flooding technique by breaking the chain reaction of combustion without any depletion in the normal levels of oxygen. Also, listed to operate at a temperature of -40 o C.
Stat-X is also tested for military standards, where it successfully passed the vibration, shock, temperature shock, water, and oil immersion tests.
In this application, Stat-X electrical activation system is installed with a linear heat detection cable, being a light weight and pressure free system made it easy and safe to install.
Since these vehicles are mobile the fire suppression systems can be installed without removing the equipment from service. If the Stat-X system is removed for re-installation, it can be installed easily since it doesn’t require any piping and complex electrical wiring.
Stat-X generators can also be operated manually by including a manual pull cable or guarded toggle switch as part of the installation package.
This is a photo of the engine compartment. The generator is mounted to the upper right. The control panel used is SP-1 and detection is made with heat sensitive cable.

This project was designed, installed, and maintained by our distributor, PRIME AS, in Drammen, Norway and their partner Miljo24.
Stat-X is protecting a one of kind car, the Poteet & Main Speed Demon streamliner, the fastest piston driven car in the world. The race team and car are cutting-edge industry leaders, utilizing advanced technology in creating a car that will push speeds up to 500 mph..
Our Stat-X® fire suppression system was installed behind the firewall to protect the engine in case of fire. The Stat-X® system is a great choice because it will preserve the integrity of the electronic system while it puts out any fire that threatens the engine compartment and its components.
