Don’t wait until it’s too late to protect your off-road machinery – invest in a reliable fire suppression system today.
Trusted By:
TiboRex Absolute is a ready-to-use liquid special extinguishing agent without the addition of fluorochemicals for the highly effective extinguishing of solid fires (fire class A), liquids, non-polar hydrocarbons (fire class B) and edible fats and oils. The special formulation, whose main components are also used as food additives, guarantees exceptional extinguishing performance with unprecedented environmental protection.
Every Raptor Powder system is made up of purpose-engineered components, each designed for durability, reliability, and fast installation. From detection to discharge, here’s what makes the system work.
Avoiding the usual fuse plastic tube detection, there is only one path to the system work: stainless-steel or galvanized piping with pneumatic activation from the detection, followed by the liquid agent discharge by the same piping.
Patented technology!
Detexline® by Protecfire®, is a patented system that uses only one network of piping for detection and extinguishing.
Learn how the Detex 4MC fire suppression system detects, responds to, and suppresses fire — automatically, mechanically, and without the need for an external power supply.
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.
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.

The system is free of dangers and easy to install. It can be installed in any vehicle: Construction, mining, buses, mini-buses, vans, motorhomes, jeeps, racing cars, etc. diesel, electric or gas
The thermal detectors are placed in the upper area of the engine, in order to detect unusual heat accumulations, through temperatures previously chosen, normally our Kit for buses comes with 180ºC in the detection. In areas such as Park compartment, another lower temperature can be chosen, such as 130ºC. The dispersion nozzles are aimed at critical areas of the engine, such as turbo, exhaust, etc. This distribution makes point-to-point efficacy during extinction.
The system is applied in critical areas: engine compartment and park. It can also be applied to wheels and interiors. This system is modular and can be applied wherever desired.
TiboRex Absolute is a liquid extinguishing agent, in order to be safe and effective. Electrical components may be affected, but in any case they would be damaged by the onset of fire. All other equipment is never affected and subsequent cleaning is quick and easy. Other types of extinguishing agent (powder, gas, etc.) would not be as effective, as they can be expelled by the vehicle’s progress, not acting on fire.
No. Depending on the size and layout of the compartment. In the case of a bus engine, the job is done in about 3 hours maximum. The system is easy to assemble and also to disassemble.
No. Our system is accurate and detects temperatures with precision. Depending on the location where the thermal sensors are placed, a specific temperature is chosen only when the compartment reaches that exact temperature.
No. Our nozzles are designed to stay clean and unobstructed. Engine compartments are specifically designed, maintaining their effectiveness throughout their service life.
