FLEXXOSPHERE

Gasholder with double membrane and variable gas volume.
Standard suitable for use up to +15.0 mbar. Higher pressures possible on request.
Suitable for all wind and snow zones | Approved in all European countries.
With a Flexxovalve over- / underpressure valve for safe gas storage.

gasholder | gas storage

The Flexxosphere gasholder is designed to store hydrogen or biogas generated from organic waste in a wastewater treatment or biogas plant.
The Flexxosphere consists of two separate membranes and a gas-tight bottom liner. The outer membrane retains its convex shape due to the effect of the fan. The convex shape means the gas inside is well protected from external influences such as snow and wind. The inner membrane protects the variable gas storage tank. The Flexxovalve over- and underpressure valve ensures safe operation. This gas tank is designed to ensure a maximum lifetime and therefore optimal cost-effectiveness for our customers under all circumstances. We make this possible by choosing the best materials, by using tested components and by certified production and assembly. As standard, the Flexxosphere can withstand pressures between 0 mbar and +15.0 mbar and can handle a temporary pressure of +20.0 mbar. Higher pressures are possible on request.

gasholder | gas storage

The Flexxosphere gasholder is designed to store gas generated from organic waste in a wastewater treatment plant or biogas plant. This gasholder is designed to ensure a maximum lifespan in all kinds of circumstances and is therefore extremely durable for our customers. We realise this by choosing the best materials, the application of tested components and by certified production and assembly. The Flexxosphere can withstand a standard pressure between 0 mbar and +15.0 mbar and can withstand a temporary pressure of +20.0 mbar. Higher pressures are possible on request.

why the flexxosphere and not a regular gasholder?

Quality is guaranteed by design, production and in-house assembly under KIWA K73883 and ISO-9001.
The high quality 900 gr/m² PVC foil that is used is extremely stable and produced by a West European supplier. Other foils are possible if requested.
The Flexxosphere is standard suitable for pressures from 0 to +15.0 mbar and can handle emergency pressures from +20.0 mbar. Higher pressures are available on request.
For each gasholder you get an extensive report in which all strength calculations and conditions are described.
Our foil suppliers give a five year guarantee on the material and we give a five year guarantee on the design and processing.

Wondering what our Flexxosphere looks like in cross section?

As you can see, the Flexxosphere consists of two membranes. The outer membrane retains its beautiful stable shape due to the operation of the fan. Because of the convex shape, the gas inside is well protected against external influences such as snow and wind. The inner membrane protects the variable gas storage. The over- / underpressure valve ensures safe operation.
