DA-CG In-Line Detonation Flame Arrester

Brand: PROTEGO
The Protego DA-CG series of detonation arresters was mainly developed for the North American market and optimized to meet the demands of the US Coast Guard. 

The devices are symmetrical and offer bidirectional flame arresting for deflagrations, stable and unstable detonations. 

The speed of incoming detonations is greatly reduced by the effective shock absorber. 

This improves the flame extinction in the narrow gaps of the FLAMEFILTER.
Features
  • Offers protection against deflagrations, stable and unstable detonations
  • Less number of FLAMEFILTER discs from the use of the effective shock absorber
  • 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
  • Also available for large nominal sizes
  • Expanded application range for higher operating temperatures and pressures
  • Bidirectional operation as well as any direction of flow and installation position
  • Possible installation of temperature sensors
  • Minimum pressure loss
