Slurry protective cover

polyesterbiogasdouble membrane

HIGH QUALITY AND DURABLE Our high-quality and durable double membrane roofs are the ideal solution for flexible storage of biogas. The outer cover is a weather protection cover that protects the inner gas membrane from external influences. Our weather protection foils made of PVC-coated polyester fabric are specially designed to withstand high temperatures and thus guarantee the longest possible service life. The gas storage membrane underneath also has a high temperature stability, is highly elastic and also extremely durable. Several supporting air blowers keep the outer membrane tight and stable. This makes the weather protection foil insusceptible to wind and compensates for strongly changing temperature fluctuations. The number and size of the supporting air blowers is individually designed together with you based on various parameters and operating conditions. The air space between the gas storage and weather protection membrane also serves as insulation. The temperature gradient between the outside and biogas temperatures is kept as low as possible.
