CE-TEK’s GUA enclosures can be used to house uncertified electrical equipment. CE-TEK’s GUA flameproof enclosures are designed and engineered to contain a spark or explosion, by preventing the flame path that could be generated within the junction box. Designed for joining cables where conduit is used but have a wide range of application uses when a small junction box is required. GUAs are used in 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 IIC, IIC, II 2 G, II 2 D under ATEX 2014/34/EU Directive. Constructed from marine grade copper free aluminium, GUA enclosures meet ATEX, GOSt-K and GOSt-R standards are a rated to IP65 or IP66.

Optional extras include: epoxy painting, internal anti-condensation painting (Orange RAL 2004), drains and breather valves.
