Technical guide for designing communications networks in explosive atmosphere zones (ATEX) per IEC 60079. Kinetic Mesh in Zone 2, Ex-certified operator communications, and functional safety protocols.
Refineries, petrochemical plants, cement plants with process silos, gas plants, and warehouses with flammable vapors share a common denominator: potentially explosive atmospheres classified into risk zones by the ATEX directive.
Zone 0: Continuously present explosive atmosphere (tank interiors, process gas pipelines). No conventional electrical equipment possible.
Zone 1: Explosive atmosphere probable during normal operation (valve areas, pump seals). Only Ex "d" or Ex "i" certified equipment.
Zone 2: Explosive atmosphere unlikely during normal operation but possible on failure. Ex "n" or higher certified equipment.
Rajant BreadCrumb nodes have obtained ATEX Zone 2 certification (Ex "ec" IIC T4 Gb), enabling deployment at the perimeter of ATEX areas without full explosion-proof installation costs. When a node fails, traffic automatically re-routes through neighboring nodes in <10ms without human intervention.
Manufacturing plants with heavy machinery generate 85-95 dB of ambient noise. INVISIO M Series and T7 intercoms are designed for this environment with ATEX Zone 1/2 certification and active noise cancellation delivering clear voice even with 95 dB background noise.
Technical guide for selecting ATEX-certified electronic equipment in Peruvian hydrocarbon facilities. Zone classification, OSINERGMIN requirements, available communications equipment and sensors.
How operator communications enter the SIL-2 safety chain of a refinery. IEC 61511 requirements for Emergency Shutdown (ESD) systems, ≥99.9% network availability, and auditable voice recording in ATEX zones.
Critical communications network for an offshore platform complex on Peru's northern coast. Full redundancy, ATEX IECEx Zone 1 certification, Zetron dispatch integration, and operator's OSHSec protocol compliance.
