The Elmac Technologies® ESA Series of End-of-Line Flame Arresters are designed specifically for short time burn events.
The Elmac Technologies® EVA Series End-of-Line Deflagration Flame Arresters are designed to be installed at the end of a pipeline or exit vent from a vessel. They provide protection against atmospheric deflagrations, where the ignition source is external.
The EVA Series incorporates Elmac’s E-Flow™ enhanced crimped-ribbon technology in the flame arresting element. The matrix of the arrester 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 flame arrester and into the protected vent line.
Elmac EVA Series End-of-Line Arresters are ATEX certified for gas explosion groups IIA1 & IIA at a maximum operating temperature of +60°C.
