EXPLOSION DOORS: Self reclosing, resettable & re-useable venting doors, plant & buildings cement
The TV Explosion Door from ATEX is a high performance explosion venting solution for aggressive environments. It provides economical explosion relief and prevents secondary fire damage from oxygen intake by rapidly re-closing after the explosion is vented. We also offer a light weight door for building protection.
Features
- Fast response time
- High efficiency vent area
- Designed for aggressive environments
- Long service life (low maintenance)
- Low cost of operation
- Spring-assisted automatic re-close prevents oxygen ingress and the 'chimney' effect.
- Air-cushion design causes smooth deceleration, avoiding damage to the supporting structure.
- Optional vacuum breakers protect against implosion caused by rapid air cooling inside the vessel.
Available Options
- Construction: hot-dip-galvanised steel or stainless steel.
- Vacuum breakers
- Heating system (prevents obstruction by freezing weather)
- Proximity switch (can be used to actuate secondary protection devices)
Concept and Operation
Self-re-closing 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 re-closes and the unique door catches reseal the vent opening, minimizing 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.
