LDA Liquid Detonation Flame Arrester

Brand: PROTEGO
The Protego LDA series of liquid detonation arresters was developed for storage tank filling lines that are not continuously filled with product and sometimes contain a combustible mixture. 

The device is installed inside the tank at the end of the line and prevents the combustion from being transferred into the tank if the explosive atmosphere ignites. 

The liquid detonation arresters function according to the siphon principle in which the liquid product serves as a liquid barrier to flame propagation.
Features
  • Simple construction that helps prevent soiling
  • Low pressure loss
  • Provides protection from deflagrations and stable detonations
  • Useful for nearly all flammable liquids
  • Meets TRbF (Technical Regulations for Flammable Liquids) requirements
  • Deliverable with different outlets
