How it Works
product key technologies
Manual Model
Operators can activate the system manually via the control panel button or external pneumatic actuator.
Ideal for emergencies where immediate human intervention is required.
Automatic Model
The detection cable continuously monitors the protected area.
Once the temperature reaches 138°C or 180°C, it sends a signal to the control panel. The solenoid valve is activated, releasing expellant gas into the agent bottle. The fire suppression agent is discharged through nozzles into the hazard area.The system also triggers an alarm and can shut off the engine automatically.
The system continuously monitors temperature through a linear heat detection cable installed in critical zones.
Once the preset temperature is reached, the system automatically activates:
Heat Detection
The thermal sensing cable identifies abnormal temperature rise in protected areas.
Signal Transmission
A signal is sent to the control unit immediately.
Automatic Activation
The control unit triggers the valve system.
Agent Discharge
Dry powder is released through nozzles directly onto the fire source.
Fire Suppression
The powder quickly interrupts combustion and prevents re-ignition.
1. Automatic Temperature Activation
* How It Works: Flexible detection cable is routed through high-risk areas (e.g., engine bay, hydraulic systems) to continuously monitor ambient temperature.
* Activation Process: When a fire occurs and the local temperature reaches the preset threshold of 138°C or 180°C, the detection cable instantly sends a signal to the control panel. The panel immediately activates the solenoid valve, triggering the expellant gas cartridge and discharging the fire suppression agent through the network of pipes and nozzles directly onto the fire source within seconds.
* Integrated Functions: Simultaneously, the system activates an audible/visual alarm and can output a signal to automatically shut down the vehicle's engine, ensuring full safety integration.
2. Manual Electric Activation
* How It Works: An clearly labeled "MANUAL START" button is conveniently located on the control panel within easy reach of the operator.
* Activation Process: If the operator detects the initial signs of a fire, pressing this button directly energizes the solenoid valve, bypassing the detection cable and releasing the agent immediately.
* Key Advantage: Provides operators with immediate intervention capability, serving as a crucial and direct backup to the automatic mode.
3. Mechanical Emergency Activation
* How It Works: This is a purely pneumatic (mechanical) activation method, independent of the vehicle's electrical system. A manual actuator pull-box is typically installed externally on the vehicle or within the cabin.
* Activation Process: In an emergency, pulling or pressing this mechanical actuator releases high-pressure gas directly, which acts on the pneumatic valve to open the agent cylinder.
* Key Advantage: Guarantees system activation even in extreme scenarios like total vehicle power loss or control panel failure, providing the ultimate failsafe protection.
Self-Diagnostic System
The system features self-check alarm functionality. When detection cables are disconnected or damaged, the control panel will issue an alarm indicating the system is in fault condition, ensuring the equipment always maintains normal working status.
Products Application
Ideal for a wide range of vehicles and machinery. including but not limited to:
- Mining (haul trucks, loaders, drilling rigs)
- Construction (excavators, bulldozers)
- Transportation (buses, special vehicles)
- Agriculture & forestry equipment
- Waste management and recycling machinery
It is particularly effective in protecting engine compartments, hydraulic systems, and electrical areas, where most fires originate.
Installing a vehicle fire suppression system helps:
- Protect high-value equipment from fire damage
- Reduce downtime and operational losses
- Improve operator safety
- Meet international safety regulations
- Lower insurance risks and maintenance costs
In addition to the cartridge model, we also have pneumatic model and electrical models fire suppression systems.
Here are some pictures for reference.
