Principles of Operation

The Elmac Technologies® SV Series of Light Duty End-of-Line Flame Arresters are designed for installation at the end of a pipeline, or on an atmospheric vent, from vessels where flammable gases or vapours may be present. SV Flame Arresters provide a cost-effective solution for situations where a simple lightweight product is required. Typical applications include gas purging of equipment and sample or instrumentation lines.

The Elmac SV Series Flame Arresters use elements with small apertures which allow gases or vapours to pass. 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.

Explosion Groups

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

Standards Compliance

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