gas storage

A suitable storage tank must be gas-tight, pressure-resistant, UV-resistant, temperature-resistant and weather-resistant to ensure safety in operation. WE OFFER YOU A WIDE RANGE OF FOIL STORAGE UNITS:

originals - built to las- since 2002

The “Black Beauty” already protects countless fermenters since 2002. Often copied, but never reached you will find the “original” only with us.



Biolene Gas Storage


Our single-shell Biolene® biogas storage membrane, proven thousands of times in practice, is an economical solution for your biogas plant. Biolene® is a gas storage tank and tank cover in one and thus offers a highly efficient solution for small agricultural and industrial biogas plants.

Due to weather influences, high demands are placed on the outer skin of the digester roof. Our Biolene® meets these high demands: it is made of high-quality EPDM rubber. The material impresses with its UV, ozone and temperature stability, is highly elastic and durable.


Depending on the biogas production, the operating mode of the CHP unit or due to maintenance, the stored gas volume changes constantly. The flexible outer skin rises and falls depending on the filling quantity and the filling level is always immediately visible. In addition, it is possible to precisely determine and evaluate the fill level with the help of an electronic fill level measurement.

A wooden beam ceiling serves as a substructure. The laid planks and the ceiling are a very large colonisation area where sulphur bacteria can settle. The biogas produced is thus cheaply and reliably pre-desulphurised.

from "Black Beauty" to double membrane

double membrane gas storage roof

the resistant gas storage

double membran gas storage


Our high-quality and durable double membrane roofs are the ideal solution for flexible storage of biogas. The outer cover is a weather protection cover that protects the inner gas membrane from external influences. Our weather protection foils made of PVC-coated polyester fabric are specially designed to withstand high temperatures and thus guarantee the longest possible service life. The gas storage membrane underneath also has a high temperature stability, is highly elastic and also extremely durable.

Several supporting air blowers keep the outer membrane tight and stable. This makes the weather protection foil insusceptible to wind and compensates for strongly changing temperature fluctuations. The number and size of the supporting air blowers is individually designed together with you based on various parameters and operating conditions.

The air space between the gas storage and weather protection membrane also serves as insulation. The temperature gradient between the outside and biogas temperatures is kept as low as possible.
