Optimum storage volume for your biogas plant The Cogatec double membrane gasholder is the ideal biogas roof for storing biogas. The geometry of the different spherical shapes ensures that the optimum gas storage volume is utilised. Monitoring is carried out by our state-of-the-art laser measuring system. Our system enables a flexible mode of operation. The roof system, designed for biogas plants, agricultural operations as well as sewage treatment and industrial plants, consists of two separate, high-frequency welded polyester membranes that are PVC-coated on both sides. The fabrics used impress with their low gas permeability, very high UV stability and the special, dirt-repellent top layer. The outer membrane of the double membrane gas reservoir absorbs the static loads caused by wind and snow loads. This allows the inner membrane to be operated almost without pressure, thus enabling a longer service life. Our membranes are provided with a keder in the clamping area, which diverts the forces arising from weather influences into the anchoring clamping rail in a form- and force-fitting manner. Double Membrane Gasholder The Cogatec double membrane gasholder is a roof system for storing biogas that is placed on top of a tank. The high-frequency welded membrane roof is attached to the container crown by means of a stainless steel clamping ring. To ensure the tightness of the clamping rails, the substructure is attached directly to the inside of the container.
