Be it in the pharmaceutical industry, in oil and gas processing or in the food industry: Many companies have explosion hazard areas, where gases, vapors or dusts can form an explosive mixture in combination with air. To prevent such a mixture from igniting, there must not be any flying sparks from electrical equipment. Accordingly, these areas must comply with certain safety guidelines, also when it comes to choosing a suitable door operator or control system.
And this is where our ATEX operators and ATEX control units come in!
The term ATEX is derived from the French expression “Atmosphères explosibles” and refers to the European directives for explosion hazard areas. In order to protect persons in such areas, there exist regulations for placing electrical and mechanical equipment on the market and operating them, as well as monitoring and control devices.

For gas and dust processing, we offer solutions for gas (Zone 1 and Zone 2) and dust (Zone 21 and 22). All operator and control components meet the requirements arising from use in explosion-protected areas and thus ensure safe operation. This also includes not using emergency hand chains. Emergency operation is therefore only possible using a crank. As protection against overload and short-circuits, the motor protection switch prevents the housing surface from overheating.
Key Features at a Glance
