Low pressure gasholder

 Low Pressure Gas Holder NOXstore (1)

Low pressure gas holder NOXstore

For the temporary storage of bio or sewage gas 
in a zero pressure environment conforming to the technical norms (DVGW, ÖWAV, SUVA, safety regulations for agricultural biogas systems SWA). The gas holders are available in various storage capacities ranging from 10 – 7,500m3. The storage of the biogas/sewage gas is achieved with a cylindrical gas bag which is freely hung in a building or silo. The silo serves, in this case, as an effective supporting and protective construction. The outside surface of the silo can be powder coated in any colour specified by the customer.

The gas bag is manufactured from a high quality polyester membrane (non-flammable, fungus repellent and methane/UV resistant) utilising
 the most modern frequency welding techniques.
