Abort gates are high-speed dampers that are used as a safety device to protect both employees and equipment that help prevent property damage. While standard dampers are most often associated with airflow and pressure, the main goal of an abort gate is to stop the spread of a fire within a dust collection system.
Abort gates are used together with spark detection systems. When this device detects any light within the ductwork, the abort gate is activated to quickly divert sparks, flames, smoke, gases, and burning material out of the pneumatic conveying system. Abort gates are highly effective as the typical reaction time is measured in milliseconds. Spark detection can also be used to activate deluge water spray within the ductwork to eliminate flames or possible ignition potential.
The combination of an abort gate, spark detection system and a deluge water spray system offers effective protection.
If the electronic eye of the spark detection system detects light, it will engage a deluge spray downstream to try to douse the spark. The system will continue to run as normal if the spark is not detected by a second electronic eye.
Zone 2 the abort gate will be activated if the second electronic eye does detect a light after the deluge spray.
Two of the most common applications for abort gates is in dust collection systems or pneumatic conveyance of any combustible material. The abort gates can be placed in front of filters and/or baghouse collectors to protect the equipment. However, they are also placed in the ductwork system if the air is returned to the building - which reduces overall cost for makeup air replacement.
Abort gates can be customized to your specific needs. Strategically placed in your pneumatic system, abort gates reduce risk.
