ATEX Enclosures

ATEX Enclosures
Enclosures with ATEX Certification
Thorne & Derrick provide both standard and customer designed ATEX Enclosures – this includes enclosures with ATEX Certification suitable for flammable gas (Zone 1/2) and combustible dust (Zone 21/22) potentially explosive atmospheres manufactured from stainless steel, GRP or aluminium. The enclosures are classified for submersible, flameproof and explosion proof applications in onshore and offshore locations – from extensive stock we can build and populate enclosures for cost-effective electrical and instrumentation connections in Ex environments.
There is a demand for larger floor standing ATEX enclosures – this is an extension of rapid software design as Thorne & Derrick have the ability to scale up the front build process to accommodate these much larger enclosures.
The largest component approved ATEX enclosure currently stands at 2000mm(h)x1200(w)x800(d) – the build quality and material gauge are of sufficient rigidity and durability to withstand the same environmental and physical impact that the smaller ATEX enclosures must endure.
