The Elmac Technologies® LEB Series of In-line Deflagration Arresters can be designed and manufactured to meet high pressure, high temperature and short-time burn requirements.
The Elmac Technologies® DFB Series of In-line Deflagration Flame Arresters are designed to prevent propagation of flames in gas or vapour mixtures. By locating the arrester in close proximity to the potential source of ignition, any flame or explosion is confined to the immediate area.
In the event of explosion, the combustion products are cooled at the element surface by heat dissipation thus preventing continuation of the combustion process through the flame arrester and into the protected line. The flame cannot pass through the flame arrester, and is subsequently contained or extinguished.
Elmac DFB Series In-line Arresters are ATEX certified for Explosion Groups IIB1, IIB2 & IIB3.
Elmac Flame Arresters are manufactured in accordance with EN ISO 16852 and approved to ATEX Directive 2014/34/EU.
