Roof System: is a special two layer foil system.
GBE gastight roof, replace a otherwise expensive fixed roof but also withstanding storms and lasts over 10 years.
At the same time collecting the biogas, saving cost for an external gas storage.
In addition it offers the flexibility to be partly opened during operation.
Our roof is fixed with a special system that opens automatically if two other security systems fail, to make sure dangerous over- or under-pressure can lead to explosion the tank deformation.
