NPI Engineered Silo Covering Systems (Steel Roof & Anti-Algae Covers)
Engineered water tank covers designed to eliminate algae proliferation, prevent airborne dirt contamination, and stop evaporation. Options include rigid watertight Galvanized Steel Roofs up to 14.63m diameter, Airfloat UV-reflective bubble covers, and floating anti-algae nets.
System Capabilities & Design Standards
- Galvanized steel roof provides an impenetrable, watertight seal ideal for drinking water and food processing
- Airfloat polyethylene cover rests directly on the water with air-filled bubbles, reflecting UV radiation
- Floating woven anti-algae cover uses PVC buoyancy tubes to shade tanks over 10 meters in diameter
- Virtually eliminates costly water treatment chemicals by preventing photosynthetic algae blooms
Standard System Components
- 1 Interlocking Galvanized Steel Wedge Panels
- 2 Centrally Supported Ridge Cone or Truss
- 3 Dual Lockable Manhole Inspection Hatches
- 4 Perimeter Tensioning Fasteners & Seals
- 5 Floating Anti-Algae Tube Ballast Elements
