DR/SV In-Line Detonation Flame Arrester

Brand: PROTEGO
Request Information
The Protego DR/SV flame arrester series ideally combines the function of a detonation arrester with the advantages of a shut-off valve. In case of ignition, the fire can be stabilized within the flame arrester when the flammable gas continues to flow. 

Inside the detonation arrester, is a valve that closes in case of fire, stops the additional supply of fuel and extinguishes the flames. 

Temperature sensors in combination with an emergency switch off do not have to be installed if the type protego DR/SV device is used. 

This device is particularly useful for the suction-side protection of compressors and pumps.
Features
  • Protects against stabilized burning
  • No expensive emergency switch-offs are required
  • Temperature monitoring is not necessary
  • Minimum number of FLAMEFILTER discs
  • Easy to maintain
  • The individual FLAMEFILTER discs can be quickly removed and installed
  • The FLAMEFILTER discs can be individually replaced
  • Provides protection from deflagrations and stable detonations
  • Ideal protective system for vacuum pumps
