A new range of modular, explosion-proof enclosures for electrical equipment has been launched, which is not only innovatively designed, but 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 from Cooper Crouse-Hinds, represents a leap forward in terms of enclosure design, modularity and application flexibility.
Due to optimum material selection, including a high quality powder coating (>100 mm) and the use of stainless steel fixings, the GHG 64 is a compact, flameproof, copper-free aluminum enclosure with a wide temperature range from –20 degree C to + 40 degree C (-55 degree C to +55 degree C option also available).
Eleven 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 customised solutions to be assembled. Cooper Crouse-Hinds can also provide a wide variety of integrated control systems and devices, 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).
Even if the customer needs to mount the enclosures directly adjacent to one another, special stainless steel hinges can be fitted to the units by Cooper Crouse-Hinds, which enable the enclosure door to be pulled out and swung open at an angle of up to 110 degrees.
As Daniel Eichert, global product Line manager Switchgear at Cooper Crouse-Hinds states: “This innovation not only saves installation space, but also simplifies maintenance work and speeds up the repair and replacement of built-in components.”
An optional display window can be embedded in the enclosure housing, enabling the user to monitor the display and switch states of built-in components. This eliminates the cost of sourcing additional, explosion-protected indicators for the enclosure.
The GHG 64 is protected to IP65. However, this can be upgraded to IP66 by fitting an optional lip seal made from a highly heat-resistant, weather-resistant silicone.
