Fire Suppression Systems for Buses and Coaches

Discover the benefits of our UNECE R107 certified extinguishing system for buses and coaches

Fire Suppression Systems for buses and coaches

Our innovative automatic extinguishing systems and aerosol fire extinguishers are suitable for all types of buses and coaches. Every year bus fires cause major material and immaterial damage. Our aerosol generators extinguish a fire due to overheating, a technical defect or an accident quickly and effectively. Aerosol is environmentally friendly and has a long life.

Bus Fire

Our aerosol generators are already used in a wide variety of buses (e.g. by Ebusco and cities such as Zurich, Dusseldorf and Cologne) and other vehicles. Our automatic extinguishing systems provide reliable protection against class A, B, C and F fires. Unlike other extinguishing systems, complex installation and maintenance work is not required. Retrofitting is therefore possible without any problems. Our extremely compact extinguishing generators can also be housed in very narrow engine compartments and only need to be wired. No piping is required. We can use proven fire protection components for detection.

The arrival of electric buses also offers opportunities for the use of our systems and our unique extinguishing agent. We actively cooperate with various bus manufacturers and battery manufacturers to protect them against fire and prevent thermal runaway.

The simplest system variant consists of a single aerosol generator with automatic fire detection by means of a heat detection cable. This system works completely independently and autonomously without a power supply. Thousands of buses in Europe are already equipped with our systems. This includes the city of Cologne: In the tender for extinguishing technology, Regionalverkehr Köln GmbH paid particular attention to the reliability, economy and ease of maintenance of the systems to be installed. The innovative automatic extinguishing system of RSL Fire optimally meets all these criteria. Even in the narrow engine compartments of highly motorized supercars or oldtimers, our systems can be easily retrofitted and used permanently and reliably under the toughest conditions.
RSL 200CR - certified fire suppression system for buses

ECE R107 Certified

Three of our extinguishing generators with 100, 200 and 400 grams of extinguishing agent are certified according to the ECE R107 standard. With this we offer a complete solution for all types of buses. Our aerosol generators passed the demanding tests without any problems and are UNECE R107 certified by TÜV Nord.

Advantages of our Aerosol Fire Suppression Systems for vehicles

How does aerosol work as extinguishing agent?

The fire is recognized by means of a fire detector, electrical ignition or fully autonomous analog ignition. Our Aerosol generator generates the aerosol and an endothermic reaction converts potassium hydrogen carbonate into potassium carbonate, chemically removing oxidizing substances from the combustion process and extinguishing the fire. At the same time, additional heat is extracted from the combustion process. This way the fire is extinguished in two ways and the chance of re-ignition is considerably reduced. During the extinguishing process, no oxygen is extracted and the residual potassium carbonate product is environmentally friendly and easy to clean up.
