Utilizes combined explosion protection techniques like flameproof(Ex d)and increased safety(Ex e).The luminaire housing is extremely robust to withstand internal explosions without igniting the external atmosphere.All joint surfaces(e.g.,between cover and body)have precisely engineered flame paths(gaps and lengths).Cable entries use certified Ex cable glands.Heat dissipation is managed via carefully designed fins to ensure surface temperature stays below the marked temperature class(T-class).
Selection must strictly follow the hazardous area classification(Zone 0/1/2),explosive gas type(IIC,IIB,IIA),and auto-ignition temperature of the installation site.All materials should resist chemical corrosion.Maintenance and lamp replacement require special tools and trained personnel.They usually lack built-in lowering mechanisms,requiring Ex-rated mobile platforms for maintenance.
Used in oil refineries,offshore platforms,LNG terminals,chemical tank farms,paint spray booths,and other locations classified as hazardous areas.Installation locations and quantities must be determined by professional safety assessment.Lighting must meet visual task requirements within the hazardous zone.
