Flameless explosion relief device designed specifically for use in standard or hygienic applications where flammable dusty substances are handled. The technology includes explosion protection for equipment such as product containers, dust collectors, silos, dryers, bucket elevators and other mechanical conveying devices.

When an explosion occurs, the vent opens and vents the explosion pressure through a flame arrester, cooling the hot gases and smothering the flame.

The flameless vent is self-closing, reducing downtime after an event.

Key features:

Provides explosion pressure relief without flame emission

Opens at low pressure (0.05 bar g)

Self-closing and self-latching versions

Reduced downtime after explosion thanks to immediate re-closing (self-closing version)

Crevice- and hollow-body-free design reduces product residues
