Principles of Operation

The Elmac Technologies® EVB 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 EVB 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.

Explosion Groups

Elmac EVB Series End-of-Line Arresters are ATEX certified for gas explosion groups IIB1, IIB2 & IIB3 at a maximum operating temperature +60°C.

Standards Compliance

Elmac Flame Arresters are manufactured in accordance with EN ISO 16852 and approved to ATEX Directive 2014/34/EU.
