Explosion-proof enclosures for electrical equipment

21st February 2013


A range of explosion-proof enclosures from Cooper Crouse-Hinds (CEAG) are being used by MCI Electrotechnics Ltd, a supplier of electrical instrumentation and control panels, to protect a variety of electrical equipment destined for offshore and onshore oil, gas and petrochemical applications.

MCI manufactures, and if required, installs and commissions custom control panels and electrical equipment for both hazardous and non-hazardous environments around the world, including the North Sea, Middle East and Far East.

MCI supplies a diverse range of electrical control systems, including motor control centres (MCCs), junction boxes, motor starters, control panels, distribution boards and CPFG (combined pressure fire and gas) panels. On the hazardous area side of the business, MCI offers customers two main types of explosion-proof enclosure for its products: a moulded plastic (GRP) EEx de version, as well as a range of metal (aluminium / cast iron) Ex d enclosures. All of these enclosures are supplied by Cooper Crouse-Hinds.

Using the CEAG moulded plastic Ex de enclosure, MCI assembles and mounts a variety of flameproof-encapsulated components, such as fuses, contactors, lamps, MCBs, switches and meters. These impact-resistant GRP enclosures provide increased safety protection for the components. Built up units include Ex distribution boards, control stations and motor starters, all supplied to European standards EN 50014 and EN 50018. The systems are ATEX-certified for use in Zone 1, Zone 2, Zone 21 and Zone 22.

MCI also uses aluminium/cast iron CEAG explosion-proof enclosures for use with control panels, starters, junction boxes, MCCs, distribution boards and CPFG panels. MCI offers three versions of CFPG panels for A60 class modules, battery isolators and temporary power units. These ATEX-certified systems are suitable for use in Gas Group IIB installations, Zone 1 and Zone 2 areas, fulfilling the requirements of EN 50014 and EN 50018.

In late 2009, MCI supplied a motor control centre for a drilling system to be delivered to an oil and gas exploration platform in the North Sea. The 10-metre long MCC panel was built in three sections, which in total use 52 separate explosion-proof enclosures. All of the enclosures were Ex d certified and interconnected by using ‘barrier assemblies’. The entire unit has ATEX assembly certification. The remainder of the project was the build of Ex de moulded plastic lighting distribution boards. All units were EEx d certified for Zone 1 and Zone 2 areas.

In addition to supplying explosion-proof enclosures and other electrical equipment certified for ATEX environments, Cooper Crouse-Hinds also offers other hazardous area electrical equipment to IEC and NEC standards, as well as other international approvals for Eastern Europe, China and North America.
