An explosion-protected housing having a housing body, a frame part and at least two separate covers. The housing body delimits an interior space which is open at one side by means of a housing opening. The frame part has a circumferential web surrounding the housing opening. Extending within the circumferential web is a central web of the frame part that divides the housing opening into at least two opening portions. A cover abutment surface is formed, against which the covers bear in their closed position. An encirclingly closed flameproof gap is formed between each cover and the cover abutment surface when the cover is situated in the closed position and is detachably fastened by means of one or more connecting units to the frame part.

Explosion-proof housing and method for the assembly thereof

An explosion-proof housing having a cover arrangement which includes two or more covers. The covers are adjacent to a flameproof gap in the housing body (). A flameproof gap is likewise arranged between the individual covers. Special seals, more particularly in the form of a butt joint closure, are arranged on the remaining butt joints or other gaps and through-holes.

Explosion-proof housing with split cover

An explosion-proof housing having external walls, which enclose a housing interior so as to be proof against ignition penetration relative to an atmosphere at risk of explosion. At least one insert is arranged in at least one outer wall. The insert facilitates a gas flow between the housing interior and an environment around the housing. The at least one insert is configured in such a way that a gas flow having a sufficient mass flow or volumetric flow rate is permitted, but a flow connection which is proof against ignition penetration is produced. Attached to the outer wall having the at least one insert is a guiding means which together with the relevant outer wall delimits a flow channel. The flow channel defines a main flow direction of a main gas flow through the flow channel substantially parallel to the directly adjoining outer wall. In this way, the gas exchange between the environment and the housing interior can be improved and facilities arranged in the housing interior can be cooled.

Explosion-proof housing

A housing according of the flameproof encapsulation protection type having a housing body which has an opening closed by a cover. The opening is surrounded by a flange which is directed outward away from the housing body. The edge of the cover lies flat on the flange. The edge and the flange are both preferably continuous. In any case, the edge and the flange do not have any passage openings for clamping means. In order to clamp the edge against the flange, clamps are provided which hold the edge and the flange pressed against each other in the manner of screw clamps. The clamps are provided with releasable clamping means and are preferably captively retained on the housing body or the cover, the clamps being movable between a closed position, in which the cover is fixedly clamped, and an open position, in which the clamps do not extend over the cover and allow the cover to be opened unhindered.

Flameproof housing

A pressure-tight encapsulated housing () having a temperature control device () including a first heat exchanger unit () arranged in the interior of the housing () and a second heat exchanger unit () arranged outside of the housing () and which are connected to one another via a liquid cycle (). The liquid cycle () includes a feed line () and a return line () each connected to the first heat exchanger unit () and which each fluidically connect to a passage channel () of a respective leadthrough unit () arranged in flameproof manner in a wall () of the housing () so that the passage channel () extends through the wall (). The control device () further includes a liquid monitoring sensor () for generating a liquid monitoring signal (F) characteristic of the filling of the passage channels () with liquid, and a monitoring unit () for receiving signals generated by the liquid monitoring sensor ().
