External gasholder

External membrane gas storage tanks are anchored to a free-standing concrete foundation slab, or concrete foundation ring. They work on the principle of an air-supported structure - between the flexibly moving gas membrane (inside) and the outer membrane, air is permanently blown by a support fan. The result is a permanently stretched protective outer membrane and an operating air overpressure is created, at the level of which the operating gas pressure is then adjusted - ergo both are identical. The gas space of the tank from below is closed by a floor/bottom membrane, which is underlaid with a protective fleece. We supply gas storage tanks as a complete system, including filling measurement, air system, anchoring frame or overpressure valve, etc. Our chemically highly resistant gas membranes can also withstand aggressive gas components and are therefore also suitable for applications for the storage of biogas from bio-waste, industrial wastewater treatment plants, etc.

Tank mounted gasholder

Tank mounted gasholders are anchored on the top of the tanks (concrete, steel, glass coated, etc.) and the customer can choose the geometry / volume from a wide range of options. The construction works on the same air-supported (pneumatic) principle as with the above-mentioned external gas storage tanks. The gas membrane is secured from below against overhang / vacuum by a central column with belts with a desulphurisation net on their surface. It is possible to combine the gas storage tank with the passage for the service shafts of the mixers, or to wrap the gas tank around the service platform. We supply gas tanks as a complete system, including filling level measurement, air system, anchoring frame or overpressure / underpressure valve, etc. Our gas membranes are chemically highly resistant to aggressive substances that occur in biogas from bio-waste or industrial wastewater treatment plants, etc.

Rectangular gasholder

The double-membrane gas storage tank can also be installed on tanks with a rectangular / square floor plan, as well as on lagoons. Again, the same principle of air-supported construction applies as for the above-mentioned, as well as the scope of delivery in the form of a complete system, as well as the high chemical resistance of the gas membrane.

Gas bag

It is the simplest and pressureless form of biogas storage. However, it is necessary to place the gas bag in a building, tank, container, etc. to ensure protection against wind, snow, etc. In addition to the fixation in the protective building, it is necessary to take into account the additional adjustment in the form of filling level measurement, overpressure valve and gas connections.
