The Elmac Technologies® ESA Series of End-of-Line Flame Arresters are designed specifically for short time burn events.
The Elmac Technologies® EHB Series End-of-Line Deflagration Flame Arresters are designed to be installed at the end of a pipeline or exit vent from a vessel. This provides protection against atmospheric deflagration, where the ignition source is external.
The EHB Series incorporates Elmac’s E-Flow™ enhanced crimped ribbon technology in the flame arresting element. The matrix structure has been optimised using Computational Fluid Dynamics (CFD) to ensure industry leading flow and pressure drop characteristics.
During a deflagration, the combustion products are cooled at the element surface by heat dissipation. This prevents continuation of the combustion process through the arrester and into the protected vent line.
Elmac EHB Series End-of-Line Arresters are ATEX certified for gas explosion groups IIB1, IIB2 & IIB3 at a maximum operating temperature of +150°C.
