Spark Detection and Suppression

Rapid response spark detection and fire extinguishing systems

The ATEXON spark detection and fire extinguishing system by IEP Technologies is designed to reduce the risk of ignition sources as conveyed burning embers from entering hazardous areas such as silos and filters which can then lead to consequential dust explosions. The Atexon range of spark detectors are extremely reliable, fast, sensitive and designed to detect ignition sources in milliseconds and to initiate water extinguishing. The extinguishing process normally lasts for 5 seconds and stops automatically.


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

Operating principle of the spark detection and fire extinguishing system

  1. The spark detectors respond to ignition sources within milliseconds.
  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 and gives audible and visual alarms.
  5. The fan controller stops the blowers in case of overheating or a spark shower.
  6. The overheat sensing cable monitors the fan bearings and the casing.
  7. The pressure booster controller guides the water pump and the heat tracing cables.
  8. The pressure booster provides the extinguishing water at the correct pressure without any air pockets.
