DR/EU In-Line Detonation Flame Arrester

Brand: PROTEGO
The Protego DR/EU series of in-line detonation flame arresters represents a further development of Protego flame arresters DR/ES used successfully for decades in industry. 

The device protects against deflagrations, stable and unstable detonations. 

The classic right angle design offers considerable maintenance advantages in comparison to a straight through design.
Features
  • Minimum number of FLAMEFILTER discs due to the effective shock absorber
  • Quick removal and installation of the complete PROTEGO flame arrester unit and of the FLAMEFILTER discs in the cage
  • Modular flame arrester unit enables each individual FLAMEFILTER discs to be replaced and cleaned
  • Provides protection from deflagration as well as from stable and unstable detonation
  • The right angle design saves pipe elbows
  • Extended application range for higher operating temperatures and pressures
  • Minimum pressure loss
