Concept and Operation

Self-reclosing Explosion Doors open against one or more baffle plates to absorb its kinetic energy. This dramatically reduces damage to the supporting structure. After venting the door recloses and the unique door catches reseal the vent opening, minimising the damage from fire. In contrast, standard Explosion Vent Panels allow air supply into the protected vessel after the initial explosion, increasing the potential damage from fire, especially in dust collectors and silos.

The explosion doors can be round or rectangular, to facilitate most industrial applications. The round explosion doors are ideal for silos and other vessels requiring top-mounting. The rectangular explosion doors are available for heavy and light industrial environments. The units can be mounted in a horizontal or vertical position. The heavy industrial explosion doors are used on vessels such as dust collectors. The light industrial units can be used on weak structures such as buildings. After explosions in virtually closed vessels, rapid cooling can cause destructive vacuums. An integrated vacuum breaker is available to prevent implosion.
