This design makes possible the storage of fermentation substrate and biogas in one tank. The tank walls are produced out of steel, stainless steel or enamelled steel. These different materials are also distinguished by their high resistance to the corrosion usually caused by fermentation substrate and biogas.
For roof construction, gas depots made from PVC and/or EPDM foil are used – substances which have proven impermeable to methane gas.
The foundation of the gas depot comprises central support made of stainless steel 1.4571 (AISI 316Ti) and a belt substructure. Concerning agitator technology, submersible agitators and/or long-shaft agitators are used. Our scope of delivery includes continuous measurement of gas levels as well as DEKRA-approved protection against overpressure and underpressure.
