Our product range contains a wide variety of enclosures which offer a selection of sizes, designs and materials. It is designed for single installations as well as for large distribution units. The dimensions of the enclosures are so designed that they can be combined into a large modular unit. A large number of components, such as contactors, switches, instruments and PLCs can be built into these enclosures. Naturally, customer-supplied equipment layout is designed by us to customer's requirements. Cable entry is either direct (cable glands or conduit entries) or indirect via en EEx e housing (stud-type or conductor bushings).
The design and installation of explosion-protected distribution and control boards having flameproof enclosures require considerable experience and careful consideration of relevant regulations in relation to the application data. Only thus are technically and economically satisfactory solutions, which combine a user-friendly design with a high degree of safety, possible. In addition to Ex-regulations, the general regulations must all be bserved in the assembly of distribution and control boards.
Standard industrial electrical equipment can be bult into enclosures. It is, however, subject to a "type test" by a recognised testing station. R. STAHL has such certificates issued by PTB permitting the assembly of explosion-protected systems for all standard applications.

Under ATEX, the requirements placed on EX enclosures for use
in explosion hazard atmospheres are high.
For this reason, Rittal refuses to compromise in this area. Enclosure concepts proven a million times over are tailored to the specific Ex requirements.
The results is a series of empty enclosures providing ideal conditions for applications in the chemicals
and petrochemicals industries, in the offshore sector
and in the foods industry.

We were dissatisfied with what was available for mounting single and multiple rail-mount instruments in the field, so we designed our own. Made of metal with a rugged clear polycarbonate cover, the R-BOX meets standards for enclosing indoor and outdoor electronics approved for use in instrinsically safe and non-incendive areas. It installs quickly and easily on a surface or pipe, or in a panel.
Use the R-BOX with our SPA and SPT Site-Programmable Alarms and Transmitters, TRY and SIY PC-Programmable Transmitters, and our complete line of economical ECT Signal Isolators, Converters, Repeaters, and Splitters.

The recently developed CUBEx control enclosure product line from R. STAHL now makes it possible to combine compex control and distribution panels into comprehensive, space-saving units. Adds a whole new dimension to individualised and flexible solutions for your applications. Other customer-specified control and distribution panel designs are also possible. The CUBEx system increases the flexibility of your applications and ensures that all internationally recognised installation technologies can be employed. All standard, commercially-available electrical equipment can be installed. The space-saving design of this IIB enclosure enables a mounting distance of just 10 mm between units. Moreover, flameproof enclosures incorporating "D2D" technology enable the direct connection enclosures or terminal chambers are required. CUBEx is the logical next step in the development of IIC tchnology integrated in the renowend 8220 Series. For use in Group IIB hazardous areas in Zone 1 and Zone 2 or Zone 21 and Zone 22.
The main connection switch of the lighting and heating panels CUBEx Series 8264/5-ExV is operated through the side wall via an actuation mechanism. The circuit breakers are fitted on the second mounting level and are actuated via totary drives. As an option it is possible to fit test keys to the ELCBs to make it possible to actuate the back wall of the enclosure for fixing the devices. Cable entry is done directly via tapped holes, wired directly to the switches. For current distribution the original comb type rails are used at the switching units. A typical design allows for 12 or 24 circuit breakers. Different designs upon request.

THERM HI "smart heater" is a system consisting of
an explosion-proof electric heater and a
microprocessor, designed to control the air
temperature in instrument enclosures and protective
cabinets and to limit the surface temperature of the
heater.
The "option E" is equipped with an intrinsically safe
sensor, thus allowing measurement and accurate
regulation of the temperature of the instruments and
equipment (e.g. of manifolds).
... THERM HI heaters are designed to solve
sophisticated and complex heating problems in
hazardous areas, and in particular for high
temperature maintenance of analyzing equipment.
