PROTEGO® Detonation Flame Arresters

The in-line detonation flame arresters type PROTEGO® DA-SB are the newest generation of flame arresters. Based on flow and explosion dynamic calculations as well as decades of field tests, a product line was developed that offers minimum pressure losses with maximum safety. The flame arrester uses the Shock Wave Guide Tube Effect (SWGTE) to separate the flame front and shock wave. The result is an in-line detonation arrester without a classic shock absorber, which minimizes the use of FLAMEFILTER® discs.
Benefits:
– optimized performance due to the patented Shock Wave Guide Tube Effect (SWGTE)
– low number of FLAMEFILTER® discs due to the patented Shock Wave Guide Tube Effect (SWGTE)
– modular design enables replacement of the individual FLAMEFILTER® discs
– different designs allow scalable pressure loss over the area of the FLAMEFILTER®
– maintenance-friendly design
– advanced design for higher operating temperatures and pressures
– bi-directional operation, as well as any flow direction and installation position
– installation of temperature sensors possible
– minimal pressure loss resulting in low operating and lifecycle costs
– cost-effective spare parts
– installation of stabilized FLAMEFILTER® possible
– use of maintenance-friendly PROTEGO® flame arrester unit possible
