By using BRILEX Explosion Vents in combination with a unique BRILEX Ceramic Filter, economical venting of dust explosions is possible. When the vent opens during an explosion, the ceramic filter retains the dust and cools down the hot gases. Existing quench pipes are uneconomical, not re-usable or have lower venting efficiencies requiring high vessel strength. The BRILEX IndoorVent offers unlimited use with the highest known efficiency. Due to high investigation costs and bad efficiency, design engineers and end users tried to find alternatives. The BRILEX IndoorVent offers a combination of a fast opening BRILEX Explosion Vent with a high efficient ceramic filter. The vent area of the IndoorVent is greater than the vent areas of existing quench pipes. After an explosion the IndoorVent can be re-used. The result is a cost effective solution for plant designers and end users for all industries.
