Explosive gas and dust atmospheres are a special challenge in fire protection.
Fire Detectors with Explosion Protection
Our ADICOS fire detectors are also available in variants for use in potentially explosive gas and dust atmospheres. They are type-tested or approved according to the ATEX Directives or IECEx Scheme. ADICOS fire detectors for potentially explosive atmospheres are technologically and structurally designed to ensure reliable fire detection despite high dust and gas concentrations. They are designed differently for ATEX zones 0 to 2 (gases) and 20 to 22 (dusts), i.e. depending on the probability and duration of the occurrence of an explosive atmosphere.
Areas in plants and structures in which an explosive atmosphere may develop are classified into different zones according to the ATEX directives, depending on how frequently and permanently this hazardous atmosphere occurs. ATEX zones 0, 1 and 2 apply to gases and are equivalent to zones 20, 21 and 22 for dusts. We offer our different ADICOS detectors for the different ATEX zones depending on the gas or dust hazard.
