Our advanced safety solutions – including   Flame Arresters Flame Arresters A flame arrester, deflagration arrester, or flame trap is a device or form of construction that will allow free passage of a gas or gaseous mixture but will interrupt or prevent the passage of flame. and Pressure/ Vacuum Vacuum Vacuum is the pressure in an enclosed space that is lower than the ambient pressure. Relief Valves – ensure efficient waste management and reliable environmental protection.​
Tailor-made safety concepts are designed to meet each customer’s specific requirements while complying with local standards and regulations, ensuring safe and fully compliant operations which are simple to maintain during the life of the asset.

Protection of Waste Water Treatment Plants

Wastewater treatment plants generate biogas during anaerobic digestion, which is routed to storage tanks, treatment units, gas pipelines, and utilization systems such as CHP units or flares. Each section is exposed to specific conditions, including pressure fluctuations, vacuum situations, and the risk of flame propagation.​

Pressure / Vacuum relief valves and Flame Arresters Flame arrester Device fitted to the opening of an enclosure, or to the connecting pipe work of a system of enclosures, and whose intended function is to allow flow but prevent the transmission of a flame. are installed on digesters, storage tanks, gas boosters, and flares. These  Flame Arresters protect downstream equipment Equipment Machines, appliances, fixed or mobile devices, control parts and accessories, and warning and prevention systems, whether separate or combined, intended for the generation, transfer, storage, measurement, control, and conversion of energy, and for the processing of materials, which have their own potential source of ignition and may cause an explosion. and prevent flame transmission, ensuring proper tank venting, effective emission control, and safe isolation of potential ignition sources.

    Protection of 
    Landfill Plants

    Landfill gas collection systems transport combustible gas from extraction points to utilization or flaring units, operating under varying flow rates and pressures and requiring protection against flashback Flashback Phenomenon occurring in a flammable mixture of air and gas when the local velocity of the combustible mixture becomes less than the flame velocity, causing the flame to travel back to the point of mixture. , deflagration Deflagration Explosion propagating at subsonic velocity (EN 1127-1:1997). , and endurance burning Endurance burning Stabilized burning for an unlimited time. . ​

    Protection includes in-line Deflagration and Detonation Detonation Explosion propagating at supersonic velocity and characterized by a shock wave (EN 1127-1: 1997). Flame Arresters in gas lines and at flares. Equipment placement ensures safe gas transport and reduces the risk of flame propagation back into the collection network.
