ETX™
Self reclosing and reusable explosion door for drying systems.
Drying processes in the food industry are often associated with the generation of explosive atmospheres. The application of explosion protective systems is imperative, in particular due to the high probability-occurrence of glowing embers and hot surfaces. As a result of the function-related elongated design of ring dryers, post-explosion-fires in ring dryers are boosted by the so-called chimney effect, if the pressure relief devices remain open after an explosion. The REMBE® explosion door ETX™ prevents post-explosion-fires by self-reclosing after the explosion pressure has been relieved, thus preventing the supply of oxygen to the air. After successful relief the ETX™ will remain undamaged and will be ready for the next usage.

reclosing.
- Ring dryer: An optimal and safe pressure relief is achieved by attaching the ETX™ to the deflection hood or ring duct.
- Cyclone (multistage): The most effective arrangement of explosion vents for inertial separators is directly above the immersion pipe.
- Bag filter: In the case of bag filters, special care must be taken to ensure that the venting devices are placed below the filter elements. This ensures that filter elements do not block the vent areas.
