ENARDO Detonation Flame Arrestors provide protection against flame propagation in piping systems that are manifolded or have long run-up distances. Our design is unique in the ability to provide larger flame channels that allow for less frequent plugging and easier cleaning when service is required—both of which translate to less down time. ENARDO Detonation Flame Arrestors are bi-directional and proven to stop an ignited flammable vapor mixture approaching from either direction and traveling at subsonic or supersonic velocities. Our patented element offers maximum flow to pressure drop characteristics.
