Flamex has been around for several decades, I believe under a couple different corporate ownerships. It is not a new technology.
I’m more used to seeing as part of an overall dust explosion control system. Usually I’ve worked with a mechanical engineer whose specialty is dust explosion control. Most common is the pair of spark detection, spark suppression, then downstream again, spark detection. Second detection series releases abort gate. Current retroactive standards for dust systems are going into effect. Expect more discussion. ..... Stay back from abort gates. Anything that you need to reset with a come along, and trips too fast for eye to see is hazardous in its own right. Best.
