Description

CE-TEK’s EJB flameproof enclosures are designed and engineered to contain a spark or explosion, by preventing the flame path that could be generated within the enclosure. Suitable for many hazardous areas, including petrochemicals (gases and vapours), mining (coal and metallic dusts) agricultural and food processing/production (flour, sugar and grain dusts) where combustible dusts and gases are present e.g. zones 1 and 2 (gases), 21 and 22 (dusts) Ex d IIB, IIC, II 2 G, II 2 D under ATEX Directives. Constructed from marine grade copper free aluminium or 316L stainless steel, EJB enclosures meet ATEX 2014/34/EU, IECEx, GOSt-K and GOSt-R standards are a rated to IP65 or IP66.

CE-TEK’s EJB enclosures can be used to house uncertified electrical equipment.

Optional extras include: epoxy painting, internal anti-condensation painting (Orange RAL 2004), GUB O-ring gaskets, EJB glass windows, drains and breather valves.
