DA-SB In-Line Detonation Flame Arrester

Brand: PROTEGO
The in-line detonation flame arresters type Protego DA-SB are the newest generation of flame arresters. 

On the basis of fluid dynamic, explosion dynamics calculation and decades of experience from field tests, a product line was developed that offers minimum pressure loss and 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; in addition the use of FLAMEFILTER discs is minimized.
Features
  • Optimized performance from the patented Shock Wave Guide Tube Effect (SWGTE)
  • Less number of FLAMEFILTER discs from the use of the patented shock tube (SWGTE)
  • Modular flame arrester unit enables each individual FLAMEFILTER discs to be replaced and cleaned
  • Different series allow increase of FLAMEFILTER size for given flange connection resulting in lower pressure drop across the device
  • Service-friendly design
  • Expanded application range for higher operating temperatures and pressures
  • Bidirectional operation as well as any direction of flow and installation position
  • Installation of temperature sensors are possible
  • Minimum pressure loss and associated low operating and life-cycle cost
