Spark Detection

The spark detection and fire extinguishing system works faster than the explosion

The spark detection and fire extinguishing system is designed to stop ignition sources from getting into dust explosion hazardous areas, such as silos and filters. Extremely fast and sensitive spark detectors detect ignition sources in a millisecond and start the water extinguishing. The extinguishing normally lasts for 5 seconds and stops automatically.

Our customers include companies that work in wood, bioenergy, recycling, paper, food, textile and fibre-reinforced plastic industries. Atexon products are ATEX certified by VTT Expert Services ltd. and they also conform CEA regulations.

Mounting principle of the spark detection and fire extinguishing system

1. The spark detectors detect the ignition sources in a millisecond.
2. The extinguishing unit extinguishes sparks and embers with a small amount of water.
3. The signal router guides and monitors the extinguishing event.
4. The VR18Z control panel monitors the whole system.
5. The signal device gives alarms using a siren and a strobe light.
6. The blower controller stops the blowers in case of overheating or a spark shower.
7. The overheat sensing cable monitors the blower bearings and the blower perimeter.
8. The pressure booster controller guides the water pump and the heat tracing cables
9. The pressure booster ensures airless extinguishing water with correct pressure.
