Gazex® / Gazflex®

Gazex® / Gazflex®

Fixed remote avalanche control system (RACS) based on exploding a propane/oxygen gas mixture inside an open metal tube.



→ This reference solution for preventive control consists of exploders (tubes) positioned in avalanche starting areas and connected by pipelines to a central gas unit (shelter or mini-shelter).


Functional ADVANTAGES :


EFFICIENT: « for complete control »

  • Proven over 25 years in 18 countries.
  • Available 24 hours a day, regardless of weather conditions and without special preparation.
  • Various exploder sizes available to match the type and shape of the area to be controlled.
  • Completely self-contained (power and gas) throughout the winter season, with no limit to the number of shots.
  • The explosion occurs above the snowpack which is considered the most effective method.
  • Rapid implementation: 2 minutes per firing, including its confirmation by seismometer.


SAFE: « to control the risk »
  • No explosives to handle, no human intervention in the avalanche area to be made safe.
  • No management of unexploded charges (duds).
  • No limitation associated with storing or replacing consumables
  • System fully remotely operated, can be installed in very inaccessible sites.


SIMPLE: « for a profitable investment »
  • Readily available consumables (short and long term) at low cost (propane and oxygen).
  • Training and approval requirements are minimal due to lack of explosive use.
  • Complete range of systems, adaptable to the specific ground condition and morphology of the site.
  • No polluting residue produced by the explosion.
