Atexon® by IEP Technologies extinguishing units help prevent dust explosions and fires by automatically extinguishing detected sparks. The EXT11, EXT12, and EXT22 extinguishing units have been designed for pneumatic transport duct systems moving material at very high speeds. Upon detection, a small amount of water is sprayed into the process, extinguishing the hazard without damaging the protected processing equipment. Extinguishing automatically stops a few seconds after the last spark has been detected.
