Fire suppression systems for Off-Road vehicles

The fire-suppression system is based on the principle of a fine spray extinguishing system. The protecfire nozzles spray the extinguishing agent TiboRex Absolute as very fine droplets. The extinguishing agent droplets wet, impregnated and cool the burning surfaces.
Through reflections and turbulence, the extinguishing agent also reaches adjacent areas, which enables the entire engine compartment to be protected.

– Unpressurised standby mode for improved safety: The fire-suppression system is not pressurized until it is triggered.
– Low maintenance: first regular component replacement after 5 years.
– Self-sustaining without external energy: protecfire suppression systems operate pneumatically-mechanically. This means that they do not require any additional power supply.
– Automatic and/or manual triggering: Automatic triggering is effected by fire detection elements. The fire-suppression system can also be triggered by a pneumatic manual release mechanism.

protecfire uses thermopneumatic fire detection elements to detect fire. These elements only trigger the fire-suppression system if a specified temperature is exceeded. Failure due to the failure of electrical components is thus ruled out.
Fire detection elements with different triggering temperatures can be used because the engine compartment is not a thermally homogeneous area, but contains different temperature zones.

The fire detection elements are connected to a combined control and extinguishing line, the detexline. When a fire detection element is heated to its trigger temperature, a mechanism opens the built-in argon propellant cartridge. This causes an increase in pressure in the line. The pressure increase opens an N2 propellant cartridge in the extinguishing agent container. The released propellant presses the extinguishing agent through the line to the extinguishing nozzles.

Vehicle fire protection is an essential aspect of work sites safety, as vehicles used in mining, construction or other operations are often large, heavy, and contain significant amounts of fuel and lubricants, which can pose a serious fire risk if not properly protected.

Heavy vehicles, such as haul trucks, excavators, bulldozers, and loaders, operate in harsh and demanding environments, often in close proximity to flammable materials and explosive atmospheres. These vehicles are critical to the productivity and efficiency of site operations, and any downtime or damage caused by a vehicle fire can result in significant losses in terms of both time and money.

In addition to the risk of property damage and equipment downtime, vehicle fires in mining can also cause serious injury or even fatalities to mining personnel. In a confined underground mine environment, for example, a vehicle fire can rapidly spread, creating a life-threatening situation for miners working in the area.

Therefore, implementing vehicle fire protection measures, such as installing automatic fire suppression systems, and ensuring proper maintenance of the vehicles, is crucial in preventing vehicle fires and minimizing their impact if they do occur. Such measures can also help companies comply with local regulations and industry standards for safety in the workplace.

Overall, vehicle fire protection is an important aspect of mining safety and can help to ensure the safe and efficient operation of mining vehicles while protecting personnel, property, and the environment from the devastating effects of fire.
