Flame Arresters

Flame Arresters are designed to allow the flow of gases, liquids, etc. and to prevent flame transmission. PROTEGO® Flame Arresters are composed of individual FLAMEFILTER® (flame arrester discs), spacers, and a casing. The FLAMEFILTER® is made of wound, corrugated metal strips. The principle of flame quenching in small gaps is applied in PROTEGO® end-of-line flame arresters and PROTEGO® in-line flame arresters.

Special features and advantages of PROTEGO® Flame Arresters:

  • Modular Flame Arrester unit enables each individual FLAMEFILTER® Dics to be replaced and cleaned
  • Service-friendly design
  • Minimal Pressure loss and associated low operating and life-cycle cost

PROTEGO® Valves help to reach Net Zero for a Sustainable Future Due to the highly developed manufacturing technology of PROTEGO® Valves, the tank pressure is maintained up to set pressure with a tightness that is far superior to the conventional standard. According to the PROTEGO® Standard PS-001, leak rates are measured at 90% of the set pressure. This testing ensures PROTEGO® Valves exceed the most stringent leakage rate requirements of EPA, API2000 and EN ISO 28300.
