Ex-proof enclosures

A range of modular, explosion-proof enclosures for electrical equipment has been launched by Cooper Crouse-Hinds, which can also be tailored to suit the exact requirements of the application – whether for an onshore oil refinery, offshore oil platform or in a harsh industrial environment such as a chemicals plant. The GHG 64 Ex-d enclosure series offers a high quality powder coating (>100 m) and the use of stainless steel fixings, It is a compact, flameproof, copper-free aluminum enclosure with a wide temperature range from –20 to 40ºC (-55 to +55ºC option also available). 11 different sizes of enclosure are available, from W210 x L210 x D191mm, up to W650 x L650 x D442mm. These can be installed in hazardous gas (Ex-d IIB or optional Ex-d IIB + H2) or hazardous dust areas (tD). Rated voltage is up to 690V and rated current is up to 1150A. The GHG 64 can be interconnected using flameproof bushings, which enables large, complex customized solutions to be assembled. A wide variety of integrated control systems and devices can also be provided, such as contactors, MCBs, RCDs, PLCs, WLAN, time elements, electronic components and terminals – all housed within a space-saving, fully-assembled, fully protected Ex-d enclosure. The customer can also choose from a variety of optional fittings, including a display window, frameworks for wall and floor mounting, a special hinged cover with up to 110-degree opening angle, as well as a selection of cable entry systems (Ex-d and Ex-e from CEAG and Capri).
