flexible storage and cover systems < Gastight cover The Air Blown Cover is an innovative double cover with a relatively large, variable gas-storage volume, for biogas installations and other purposes. Its shape and membrane pressure mean that weather influences have little effect on the AB Cover.

over/under-pressure valve Durable cover and gasholder THANKS TO THE HIGH CHEMICAL RESISTANCE AND MECHANICAL STRENGTH OF THE FOILS, THE AB COVER SATISFIES THE HIGHEST QUALITY STANDARDS. NEW CUTTING AND WELDING PROCEDURES ENABLE THE COVERS TO BETTER ABSORB THE BIAXIAL FORCES EXERTED ON THEM, AND THE HEMISPHERICAL CONSTRUCTION ENSURES LOW SILO WALL LOADING. The AB Cover is a double membrane cover, in which the outer cover is always pressurised. As a result, rain, snow and wind have little impact on it. The AB Cover has a huge advantage over silo roofs due to its widely variable gas storage capacity...
