DR/ES In-Line Detonation Flame Arrester

Brand: PROTEGO
The Protego DR/ES in-line detonation flame arrester has been used for decades in industrial plant construction because its right angle design offers advantages towards maintenance and costs in comparison to most straight designs. 

Once a detonation enters the device, energy is absorbed from the detonation shock wave by the integrated shock absorber before the flame is extinguished in the narrow gaps of the FLAMEFILTER.
Features
  • Minimum number of FLAMEFILTER discs due to the effective shock absorber
  • Quick removal and installation of the complete PROTEGO flame arrester unit and FLAMEFILTER discs in the cage
  • Due to modular design the FLAMEFILTER discs can be individually replaced
  • The right angle design saves pipe elbows
  • Extended application range for higher operating temperatures and pressures
  • Minimum pressure loss
