Elmac Technologies - ESA Series - Short Time Burn End of Line Flame Arresters - Brochure

Protecting People, Property and Our PlanetProtecting People, Property and Our PlanetTECHNICAL DATAFlame ArrestersESA SeriesEnd of Line Arrester with Replaceable Element forHigh Temp. and Short Time Burn ApplicationsApplication:The Elmac Technologies® ESA series end-of-line defl agrationarresters are designed to be installed at the end of apipeline or exit vent from a vessel, where the ignition source isexternal, to provide protection against atmosphericdefl agration and short time burn events.www.elmactechnologies.comPrinciple of OperationIn the event that a fl ame stabilises on the arrester element, the sudden increase in temperature would be detected bya control/monitoring system and secondary protectionmeasures implemented (inerting, shut-off valves etc).For a defl agration with no stabilised fl ame, the combustion products are cooled at the element surface by heat dissipation, preventing continuation of the combustionprocess through the arrester and into the protected vent line.Standards ComplianceESA fl ame arresters have been type-approved according to ATEX Directive 94/9/EC and EN ISO 16852.Actual device performance is verifi ed in the Elmac Technologies “state of the art” in-house test facility.Benefi tsThe ESA series incorporates Elmac’s E-Flow crimped ribbon technology in the fl ame arresting element, the metal matrix of which has been optimised using CFD to ensure industry leading fl ow and pressure drop characteristics.• Short time burn rated for early warning of stabilised burning event• Extended upper operating temperature limit• Exceptional fl ow capacities with minimal pressure drop• Easy-clean, replaceable, crimped-ribbon elements• Unique element design is less susceptible to fouling/clogging• Sizes and materials to suit a wide range of applications• End connections include fl anged or threaded options• Light weight for ease of installationExplosion GroupsElmac ESA series end-of-line arresters are ATEX approved for gases in Explosion Groups IIA1 and IIAElmac ExpertiseElmac have been manufacturing protection equipment since 1948, and bring enhanced levels of fl ame and explosion protection to a diverse range of applications. Elmac Technologies offers considerable technical leadership and using test facilities along with CFD capabilities, employs research teamsrenowned for developing solutions for the most challengingof industrial applications.EMS535425 FM535423Protecting People, Property and Our PlanetProtecting People, Property and Our PlanetESA SeriesHigh Temp.

Please contact Customer Support for details.Operating ConditionsESA fl ame arresters are equipped with a sensor allowing continuous monitoring of the element’s surface temperature. As such they provide short time burn protection for up to 2 minutes, however any secondary protection measure must be implemented within 60 seconds of detection of a short time burn event.The operating temperature range for ESA arresters is -20°C to +150°C.
