The Collar System

Choose the right buoyancy for your mission. Our Standard Closed-cell Foam Collar requires no inflation and is maintenance-free—perfect for rapid response. Need compact air transport? Choose our Air-Filled option.

Reinforced Integrity

The bottom seam sustains the highest pressure. Unlike budget single-weld tanks, Bancy applies an extra reinforcement strip over critical seams using precision hot air welding technology. This minimizes the risk of rupture during high-velocity filling from fire trucks.

Industrial Connections

We don’t limit your connections. Standard outfitted with high-strength PP flanges and Ball Valves (1″-3″). Upgrade to Aluminum Alloy Flanges for heavy-duty impact resistance. Compatible with Camlock, threaded, or Storz adapters (upon request).

Frequently Asked
Questions

Answers to common queries regarding installation and materials.

es. Our standard output is a threaded or Camlock interface. However, as a custom manufacturer, we can source and install specific fire fittings like Storz or Guillemin upon request (additional cost applies), or provide a standard thread for you to adapt locally.
Due to the massive size and drying requirements, we do not water-test every unit. Instead, we rely on a rigorous Process Control System: we perform 100% visual inspection of welds and material tensile strength testing. This ensures structural integrity while keeping lead times fast and costs reasonable for you.
Thanks to our efficient production line, small batches (under 10 units) are typically ready to ship in 5-7 days.
