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.

 
"With 24/7 availability and remote control operation, Gazex®/Gazflex® systems will ensure timely, effective avalanche control which reduces the likelihood of destructive avalanche events and allows the work to be conducted in a safe operating environment."
