OUR ENVIRONMENTAL RANGE
ENVI B400-B600
The ENVI B400/B600 booms allow stopping or diverting floating debris carried by rivers. Ideal for protecting your installations (water intakes, fish passes, etc.) or stopping the spread of invasive plants.
Composition
- High-tenacity polyester curtain with double polyurethane induction (length on request).
- Rotomolded floats incorporating ballast in their lower part to ensure the vertical position of the protection curtain.
- Product with elastic properties, giving it shock absorption capacity to reduce stress on anchorages.
- Floats placed on the downstream side of the dam to remain protected from direct impacts. The exposed side is smooth to prevent accumulation zones and facilitate the retrieval of floating debris.
- Available colors:
ENVI C550
The ENVI C550 boom is a "heavy" type boom designed to withstand significant loads. Inspired by anti-terrorist barriers, this boom stops large floating objects carried by a river during floods (caravans, cars, trees, etc.).
Composition
- Rotomolded floats filled with expanded polystyrene foam, assembled on a steel tube ensuring the mechanical "backbone" of the whole and guaranteeing excellent buoyancy and resistance.
- The tubes are connected with high-strength shackles.
- Hot-dip galvanized metal panels stop debris below the surface.
- A high-tenacity polyester curtain with double polyurethane induction ensures continuity between each metal panel.
- Available colors:
ENVI C1000
The ENVI C1000 boom is a "super heavy" type boom designed to protect major infrastructure from floating debris: large hydroelectric plants and nuclear power stations. The C1000 is an upgraded version of the C550 with a scale ratio of 2. Its ribbed hull provides very high impact resistance. Like the C550, it forms a smooth and continuous barrier that ensures excellent deflection of debris.
Composition
- Rotomolded floats filled with expanded polystyrene foam, assembled on a steel tube ensuring the mechanical "backbone" of the whole and guaranteeing excellent buoyancy and resistance.
- The tubes are connected with high-strength shackles.
- The "skirt" is made of profiled and sheet steel with a hot-dip galvanized coating. It is weighted with concrete to ensure stability even in high flow rates.
