Flexible double-membrane biogas storage systems illustrated in the 2026 catalogue in capacities ranging from 300 to 3000 m³.
Double-membrane gas holder installation
The catalogue describes a gas holder made of an inner membrane, an outer membrane and a bottom membrane. The inner and bottom membranes form the airtight biogas storage space. The outer membrane is pressurized by a control system to maintain pressure for conveying the biogas.
The brochure mentions special materials with corrosion resistance, self-cleaning properties and ultraviolet resistance.
