Gasholder - Flexxosphere
Our Flexxosphere gasholder is designed to store gases as biogas, generated from anaerobic digestion of organic waste. The inner and outer membrane of the gas holder are made of a 900 g/m² biogas resistant PVC foil and produced with hot air and/or high frequency welding techniques. The connection of the 2 separate membranes will be fixed to the concrete foundation by stainless steel pre-bended strips. A PP ventilator (300 or 800 m³/hour) with an ATEX-motor takes care of a pressure of approximately 2 mbar between the 2 membranes.
The Flexxosphere is designed for operating pressure between 0 mbar (laying on bottom surface) and +15.0 mbar and can withstand a temporary pressure of up to +20.0 mbar. Higher pressures are available upon your request.
On the bottom a biogas resistant PVC coated protection foil is positioned to assure gas tightness and prevent possible rubbing of the inner membrane.
