Elmac Technologies - Model ESA Series -Short Time Burn End of Line Flame Arresters
The Elmac Technologies ESA series end-of-line deflagration arresters are designed to be installed at the end of a pipeline or exit vent from a vessel, where the ignition source is external, to provide protection against atmospheric deflagration and short time burn situations.
In the event that a flame stabilises on the arrester element, the sudden increase in temperature would be detected by a control/monitoring system and secondary protection measures implemented (inerting, shut-off valves etc). For a deflagration with no stabilised flame, the combustion products are cooled at the element surface by heat dissipation, preventing continuation of the combustion process through the arrester and into the protected vent line.
The ESA series incorporates Elmac`s E-Flow crimped ribbon technology in the flame arresting element, the metal matrix of which has been optimised using CFD to ensure industry leading flow and pressure drop characteristics.
