Protection of Auxiliary Power Units
Sustainable Solutions for Sustainable Mobility
Over 50% of fires in diesel generators originate in electrical or mechanical components.
In its founding year of 1997, FOGTEC delivered its first firefighting systems based on the FOGTEC water mist system for generator cars to the Indian market. Since then, many locomotives, generator cars, and other auxiliary units have been equipped with FOGTEC systems. The technology has been continuously developed and optimized in terms of integration, risk adaptation, and life cycle costs. The engineering team also fully implements seamless verification. Today, generators in rail vehicles on all continents are equipped with FOGTEC systems, ensuring the required power generation for traction, lighting, subsystems, and air conditioning.
FAQ – Fire Protection in Auxiliary Power Units (APUs)
Which extinguishing system is best suited for diesel engines?
Aerosol and water mist systems are used in engine rooms, which are usually well ventilated.
Water mist is also characterized by its high cooling effect and lower corrosion impact.Can FOGTEC water mist systems be used on running diesel generators?
Yes, FOGTEC water mist can also be used on operating diesel generators;
however, shutdown of the affected units must be considered according to safety regulations to prevent damage.What type of detection is used in APUs?
In diesel-powered unit are primarily linear heat detectors.
