Weather-resistant digester-mounted double membrane biogas holder designed for integrated gas production and storage systems. This solution represents the mainstream construction mode in European biogas projects, with 80% of recent installations utilizing this integrated anaerobic reactor approach.

The digester-mounted double membrane biogas holder combines an anaerobic reactor with a top-mounted gas storage system, creating a space-efficient solution for biogas production and storage. This configuration is particularly effective for projects with medium to low daily biogas output.

• Ball-shaped structure mounted directly on tank top
• Combined tank cover and storage system functionality
• Space-saving design reduces installation footprint
• Lower cost compared to surface-mounted alternatives
• Ideal for medium to low daily biogas output projects

• Cone-shaped structure optimized for precipitation management
• Excellent snow melt and rain runoff characteristics
• Combined tank cover and storage system functionality
• Space-saving design reduces installation footprint
• Lower cost compared to surface-mounted alternatives
• Ideal for medium to low daily biogas output projects

Our digester-mounted biogas holders are manufactured to the highest standards using:

• Tear-resistant polyester fabric with special PVC surface treatment
• Acrylate varnish coating for enhanced durability
• White external membrane for high reflectivity
• Flame-proof materials meeting DIN 4102-B1 standards
• UV-resistant and low-permeability surface treatment
• Wind and snow load resistant construction
• Operational temperature range: -30°C to +70°C

Higher specification fabrics available upon request.
