Description

ACEX enclosures are manufactured from 316L stainless steel and available in 27 popular sizes ranging from 110x110x65mm to 1177x777x300mm with an orbital, bead-blast or electro-polished finish. ACEX are manufactured to the CEX specification technically but are equipped with standard hinges, hank bushes and a return flange, which allows water to drain away and provide a knife edge high grade seal.

CE-TEK’s ACEX (stainless steel) enclosures have been successfully tested to all the latest fire standards for use in buildings and infrastructure projects.

When using fire rated cables on a project, the correct specification of junction boxes can often get overlooked. When fire strikes, it is not selective in the location junction boxes and to maintain system integrity it is imperative that junction boxes are specified to the same rating as the cable being used.

The consequences of not selecting the correct type of enclosure can be huge, both financially and in terms of installation slippages. An example of this is where architects had specified fire-rated enclosures for a luxury hotel group, but electrical contractors had installed less expensive industrial enclosures that were not fire-rated, which had to be replaced throughout the hotel.

CE-TEK manufacture four series of fire rated junction boxes (CEX, ACEX, CEP and CEA), which are tested for fire to various standards including: BS5839-1: 2013 Sec 26.2e; BS EN 50200: 2006;  BS 8434-2: 2003; IEC60331-2: 2009, BS8434-2: 2003 + A2: 2009; IEC331 and BS6387-11: 1994.

Typical applications include road, motorway, rail and underground tunnels, offices, hotels and public buildings, and major infrastructure projects.
