Application
Perfect as storage tank for
- Agriculture: Membrane roof for liquid manure tank to reduce emission
- Biogas plant: gas-tight double membrane roof
- Industrial and municipal wastewater tanks: stainless steel roof
Specification
Double membrane roof
- Consisting of an outer membrane and a pressure-dependent inner membrane
- Supporting air supply including stainless steel housig provides pressurisation in the supporting air space between the membranes
- The inner membrane adjusts itself to the volume of the gas tank, with the outer membrane offering constant protection
- Sub-structure prevents the double membrane from dipping into the substrate when pressure drops during operations
- Fixing using stainless steel fixing profiles at the tank edge
- Central support made from stainless steel 1.4301 for use with liquids and 1.4571 for use with gases
- Gas fill level indicator mechanical or electric
- Suitable for use in the biogas sector
- Low methane gas permeability
GFK cover
- Available as self-supporting flat roof, smooth dome or ribbed dome (depending on tank diameter)
- Highly convex and high load-bearing capacity due to curved cover segments and radial rib structure
- Joints and seams with permanently elastic seals and special sealing compound
- No condensation on the tank wall due to a circumferential drip edge on the inside of the cover segments
- Screw connections completely made from stainless steel
- Opening with cover for maintenance and inspection purposes
