The Elmac Technologies® ESA Series of End-of-line Flame Arresters are designed specifically for short time burn events.
Elmac Technologies® ERB Series of End-of-line Deflagration Flame Arresters are designed to prevent atmospheric deflagrations from entering into a gas or vapour piping system or storage tank, when installed at the end of a vent pipe.
Elmac’s patent-protected ERB Flame Arresters incorporate the E-Flow™ enhanced crimped ribbon technology in the flame arrester element. The channel dimensions of the element are optimised for deflagration protection; whilst ensuring minimal maintenance requirements and maximising flow performance.
In the event of explosion, the combustion products are cooled at the element surface by heat dissipation, which prevents continuation of the combustion process through the flame arrester and into the protected vent line. The ERB Series Flame Arresters’ unique RE-Flow™ operating mode allows downward venting and self-draining of the flame arrester element. This ensures minimal plugging or clogging of the element under normal operating conditions and simple visual inspection.
Elmac ERB Series End-of-line Arresters are ATEX certified for gases in Explosion Groups IIB1, IIB2 & IIB3 at a maximum operating temperature of +60°C.
Elmac Flame Arresters are manufactured in accordance with EN ISO 16852 and approved to ATEX Directive 2014/34/EU.
