The Elmac Technologies® UCA Series of In-Line Unstable Detonation Flame Arresters are designed to prevent the propagation of gas or vapour explosions in pipelines under the most severe condition of unstable detonation. This type of arrester is specified for use in pipeline systems where the distance between the source of ignition and arrester is significant and/or where detonations are possible.

The combination of our unique patent pending High Energy Dissipation System (HEDS™) design and E-Flow™ technology elements attenuate the shock wave and extinguish the flame, thus mitigating the effects of an explosion by preventing its propagation. The UCA Series Flame Arrester uses an optimised crimped ribbon element which allows gas or vapour to pass through with minimal pressure drop. Designed to withstand the extreme pressures that travel at supersonic velocities in a detonation event; the UCA Series has been developed in line with Elmac’s long-standing policy regarding the provision of the utmost safety, for the protection of both plant and personnel, whilst maintaining market leading flow performance.
