The first local ex equipment manufacturer based in UAE having its hazardous area product certificates, manufacturing & integration facility in the UAE.

GUB

Explosion-proof boxes for the subsequent installation of electrical equipment of the series – GUB, GUBX

Enclosures of the series – GUB and GUBX are flameproof enclosures and meet the requirements of Directive 2014/34/EU, EN 60079-0:2012/A11:2013 have type of protection “d” according to EN 60079-1:2014 and “t” according to EN 60079- 31:2014, are intended for the installation of electrical equipment in places with the risk of an explosive environment. The shells can have various configuration options, providing reliable protection for built-in devices, terminals, devices, wires, etc.P.from external influence. The presented shells are the best solution for the subsequent assembly of finished equipment. On the outer surface of the shell there may be cable glands, drainage devices, controls, viewing windows, etc. d.

Explosion-proof enclosures differ in case design, overall dimensions, case material, presence of a viewing window.

The equipment mounted on the basis of the presented explosion-proof enclosures allows it to be classified as electrical equipment of groups I, II and III, belongs to the category 2M (mining version), 2G (gas environments), 3D (field environments). Equipment can be placed in zones 2, 3, 21 and 22. The environment may contain explosive mixtures of gases and vapors with air of category IIA, IIB and IIC, as well as IIIA (combustible flying particles), IIIB (non-conductive dust) and IIIC (conductive dust).

The shells are made of the following materials: GUB – copper-free aluminum alloy, GUBX – stainless steel. According to the manufacturing technology, the shells are divided into cast and welded.

Finished equipment based on shells can correspond to the following temperature class: T6, T5, T4, T3. When choosing a temperature class, consider the power dissipation of the enclosure, the operating temperature and the equipment used as accessories.

When mounting electrical equipment inside the shells, the following conditions must be observed that at least 40% of the cross-sectional area of \u200b\u200bthe shell remains free, for the unhindered flow of the gas flow, so as not to limit the development of the explosion.
