Abstract: The O'BellX range introduces a modular, helicopter-portable gas system for avalanche preventive release, designed for remote or environmentally sensitive areas. This system uses removable, compact gas module that can be deployed, retrieved, and maintained via helicopter without ground personnel. Key features include a patented automatic hook for single-rotation installation/removal, synchronized triggering ("Multisynch") for coordinated explosions across 2–10 systems, and an eco-friendly design with zero chemical residues and minimal visual impact. Technical specifications highlight 55–65 m effective range (25 mbar isobar at ground level) and 40–60 shots autonomy. The system's modularity, mobility, and synchronization make it ideal for isolated paths or protected natural areas, ensuring both safety and environmental compliance.
