Double membrane gas storage
The innovative solution for biogas plants
Double membrane gas holders provide innovative solutions for safe and efficient storage of biogas.
A double membrane gas holder is a flexible gas storage system consisting of two separate membranes. The inner membrane stores the gas, while the outer membrane is stabilised by the supporting air pressure and provides weather protection. The air-filled space between the membranes provides the necessary stability and leads to a safe and adaptable gas storage.

Gas storage tanks with double membrane
Regardless of tank type (installed on in-situ concrete, pre-fabricated or steel tanks or floor storage tanks), our double membrane gas storage tanks offer maximum flexibility and adaptability. They may be customised in terms of shape, design and colour in order to meet your requirements and needs.
Two different standard fastening systems can be obtained: the stainless steel U profile with clamping hose system and the stainless steel double flat profile for installation on or at the side of the wall crown.
Advantages
- High quality standard of the double membrane gas storage tanks
- Sustainable due to recyclable FPP and PE material for the gas storage foil
- Observance of the conditions on site and sensible utilisation of existing components
