DR/ES (Series 2) 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 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 temperature and pressures
  • High flow performance at small flange connection
  • Minimum pressure loss
