La série brevetée d’Elmac Technologies® de reniflard arrête-flammes (FAB Valve™) intègre un arrête-flammes RE-Flow™ avec soupape de décharge de pression et de dépression.
The increasing demand for renewable energy has intensified the need for products to protect people, process equipment and the environment. Elmac recognises this need and has developed a unique range of safety products to protect commercial, industrial and on-farm Anaerobic Digestion Plants.
The Elmac Technologies® Cowhorn Arrangement attaches pairs of Flame Arresters and Pressure/Vacuum Relief Valves to a 3-way valve, allowing the operator to switch between sets when operational or maintenance needs require.
Elmac’s world-leading Flame Arresters protect the Anaerobic Digester against fire and explosion whilst allowing gases/vapours to flow under normal operating conditions. Simultaneously, the Pressure/Vacuum Relief Valves protect the Digester against overpressure and limits product loss.
The practical duty/standby arrangement of the Cowhorn allows continuous operation with zero downtime and minimum disruption to Biogas production.
The Cowhorn can also be combined with the Elmac Technologies® Foaming Relief Vent to relieve excessive pressure during a Digester foaming event.
Elmac’s Cowhorn Arrangement has been type-tested to EN ISO 16852 and approved according to ATEX Directive 2014/34/EU.
