Electrical equipment in waste water treatment plants
With this mechanical pre-treatment, the waste water is passed through a screen or sieve. Coarse dirt of all kinds, such as stones, branches, leaves, damp toilet paper, sanitary towels and a lot of other debris, get caught there and are removed from the further clarification cycle.
Basically, different types of screens are used. These range from a few millimeters to several centimeters gap widths.
The coarse materials would otherwise clog the pumping systems and must therefore be removed safely. In addition, they also deteriorate the efficiency of the downstream biological purification stages.
Normally, these materials are collected via a screw conveyor in a container and later ends up in the waste incineration plant.
Even explosive and other dangerous substances cannot be excluded.
For this reason, the technology installed in a room with screens are subject to special requirements. For electrical equipment, this means that it must be explosion-proof in order to ensure that there is no risk of explosion as a result of possible outgassing and concentrations of the corresponding substances, and this poses a risk to the system and the people working there.
Given regulations (ATEX directive 2014/34 / EU of the European Union) and standards define the requirements for electrical equipment and their intended use in explosive areas.
Products that are used here have to be tested, certified and manufactured accordingly to the standards and regulation and carry the appropriate Ex device identification.
The QR code shown in the picture contains all the necessary data (such as the plain text) and also a direct link to the operating instructions for the equipment. This means that the operating instructions can be viewed at any time with a cell phone (approved for use in Ex areas) and adjustments made in accordance with the operating instructions. This is particularly important for distributors, since terminal adaptations according to the corresponding table in the operating instructions may also be carried out on site.
Just scan and get all the information .. it's that easy.
Examples of electrical equipment can e.g. Luminaires, terminal distributors, sockets, light switches, motors, control points, etc., which must be installed there.

Overpressure system with gas detection for hazardous areas (ATEX/IECEx)
We made a little video to show the ease of use of overpressure system in hazardous areas for un-approved devices. It is the easiest way to bring YOUR device into hazardous area too. The explosion protection at the "overpressure system 2.0" is realized by operating a non-explosion-protected equipment in a protected enclosure. This housing is protected by a durable pressure with air or an inert gas prior to penetrate the enclosure
Local Control Functions at a Fuel Loading Area
Ex certified Local control functions you find in many chemical and petrochemical Applications. A typical Application is a switch for Illumination. A big handle is therefore required to make sure that the people can switch on and off the Equipment easily also with gloves. The requirement is often very different. The showed application is a 2-pole main switch for illumination at a Tank Truck Fuel Loading Area operated by “NIS”
Modified design page for local control stations
We modified our graphical design page for Ex e localcontrol stations. Now it is possible for all 'touch-devices' (e.g. ipad, tablets etc.) to use the drag and drop function on our homepage. For desktop computers nothing changed. The difference is only in deleting a function after selection. With mouse oriented devices you use a double click and with touch oriented devices you use a 'long-tap' (min 0.8 sec) to delete
