Lignar


Our Spark Detection and Extinguishing System monitors all the duct lines passing dust and waste to the filter/silo and reduces the risk of dust fires and explosions. Immediately upon spark detection, a signal is sent to the control console which will activate a water mist spray that covers the entire cross section of the duct, extinguishing the spark in approximately 0.3 seconds. Lignar’s control console stores up to 2,500 events that can be transferred to a PC for a detailed analysis to determine hazardous areas. The automatic testing function checks sensors and extinguishing valves at regular intervals. Uninterrupted protection is also assured in case of a power failure due to the batteries used.
