Villo's Flameless Explosion Venting is ATEX certified and provides an explosion protection solution for process vessels located indoors or in areas where standard explosion venting is not safely feasible. It comprises a venting device integrated with a flame arrester. In the event of an explosion, the venting device opens to release the explosion pressure and flame, which are then directed through the flame arrester. This process effectively cools the hot gases and extinguishes the flame.
