Talk to a safety specialist
Overview
Dafo Vehicle fire suppression systems are designed to protect vehicles and mobile equipment operating in high‑risk environments. These solutions support applications across buses and coaches, material handling, forestry, mining, construction, and other demanding industries where fire risk can threaten lives, equipment, and operations.
Each system is engineered to help protect operators, passengers, critical machinery, and surrounding environments. Solutions are tailored to the specific fire risks of each application, helping deliver reliable performance where it matters most.
Electric cabinet fire suppression system PFK
As hybrid and electric drivelines become more common, fire protection requirements are expanding beyond the engine compartment. Electrical cabinets and enclosed components present new fire hazards, many of which are not suitable for traditional liquid agents.
Dafo Vehicle addresses this challenge with the PFK electric cabinet fire suppression system, based on the FK‑5‑1‑12 suppression agent. This solution is designed specifically for smaller enclosures such as electrical cabinets, offering effective protection for modern vehicle architectures.
The PFK system is a pre‑engineered solution that is easy to install and integrates seamlessly with the wider Dafo Vehicle fire protection range. Two cylinder sizes are available, allowing the system to be matched precisely to the protected volume for optimal performance.
The system is compatible with all Dafo Vehicle detection and control components and can operate as part of a larger fire protection system or as a stand‑alone solution.

Industry expertise
With more than a century of experience in fire safety, Dafo has established a strong reputation in fire suppression technology. Its vehicle systems are trusted by mining and construction operations worldwide, where reliable fire protection plays a critical role in safeguarding workers and equipment.
Tailored solutions for specific applications
Every operation presents unique fire risks. Dafo Vehicle fire suppression systems can be configured to suit specific equipment types and operating conditions, helping deliver targeted protection exactly where it is needed.
This flexibility allows systems to be adapted for different drivetrain technologies, equipment layouts, and operational requirements.
Advanced detection and suppression technology
Dafo Vehicle systems use advanced detection and suppression technology to identify fires early and respond quickly. Designed for a wide range of vehicle and equipment types, these systems help limit damage while supporting operator safety and equipment protection.
How the fire suppression system works
Dafo Vehicle fire suppression systems consist of four integrated elements: detection, alarm, suppression, and control. Together, these components deliver a fast, coordinated response to fire.
The system uses a linear heat detector wire with a fixed temperature sensor. When the activation temperature of 180°C is reached, the signal punctures the burst disc of the propellant gas cartridge. This releases nitrogen into the agent container.
The Forrex liquid agent is then distributed through the pipe network to the nozzles. At the same time, the alarm system activates, alerting the operator through an audible alarm and panel light.
The agent helps cool overheated components, suppress the fire, and reduce the risk of re‑ignition. Forrex is non‑corrosive and environmentally friendly.
The control unit includes a real‑time clock and event log, making it easier to review historical system data and previous events.Fire suppression systems for buses and coaches

HOW THE SYSTEM WORKS
1. DETECTION
A linear heat detector wire with a fixed temperature sensor monitors for heat. When the temperature reaches 180°C, the signal activates the system.
2. ACTIVATION
The signal punctures the burst disc of the propellant gas cartridge, releasing nitrogen into the agent container.
3. SUPPRESSION
Nitrogen pressurizes the agent container, distributing Forrex liquid agent through the pipe system to the nozzles and onto the fire.
4. ALARM
The alarm system is activated at the same time, warning the driver with an audible alarm and panel light.
5. CONTROL & RECORD KEEPING
The control unit includes a real-time clock and event log, providing easy access to historical system data and previous events.
The Forrex liquid agent helps cool overheated components, suppress the fire, and reduce the risk of re-ignition.
Forrex is non-corrosive and environmentally friendly.
Fast. Reliable. Proven. Engineered to help protect people, equipment and operations.
