Stahl EXpressure Ex d cabinets

Stahl’s EXpressure technology is hoping to revolutionise the science of flameproof enclosures. EXpressure safely dissipates explosive pressure inside the enclosure outwards via flow channels in a multi-layer stainless steel grid wire cloth. The wire mesh absorbs the heat energy and dissipates the pressure inside to less than 1 bar, restricting the explosive energy away from the external hazardous environment. This technology means wall thickness is reduced to just 2 mm, resulting in EXpressure Ex d cabinets being 50% lighter than traditional solid 30 mm cabinets.

The design enables low lead times in cabinet production and fast project engineering of explosion-protected control panels and distribution boards. What traditionally was housed in a 2 m-wide cabinet is now able to fit in a 1 m-wide EXpressure cabinet. The pressure venting technology enables the manufacturing of larger box volumes and removes the need for multiple small conventional cubicles. An option for double-winged doors additionally reduces installation and commissioning labour time by the removal of the centre door bar, increasing work area access and a 25% greater installation footprint.
