Our Austrian partner, SATTLER-PROTEX manufactures a wide range of materials specifically designed for the demands of Bio-gas Covers These fabrics used in applications like Double membrane gas holders,Biogas roofs,Biogas bags,

Membranes for flexible bio gas domes and water storage systems.

With more than 30 years of experience in the manufacture of coated membranes for bio gas domes storage and roofs for emission reduction, SATTLER PRO-TEX offers technical fabrics for a wide range of applications: from lightweight Type I inner membranes for gas storage to heavy Type IV outer membranes.

SATTLER PRO-TEX biogas Domes membranes are so called MLCs (Multi-Layer-Composites) whose components and structure are designed to meet the requirements of the biogas industry. Compared with common PVC-coated tarpaulins, biogas membranes guarantee reduced methane permeability and high chemical resistance.

The structural core of the membrane consists of high-strength polyester yarns that carry the static forces of a building. The polyester woven base cloth stabilized and protected by multiple layers of PVC, especially developed for bio gas domes applications. The surface of the membrane is then sealed with a specific lacquer.

As a result, the bio gas domes membranes by SATTLER PRO-TEX offer the lowest possible biogas permeability, high resistance to aggressive substances contained both in the biogas and the condensate, as well as excellent weathering resistance and long lifespan.

SATTLER PRO-TEX biogas domes membranes are easily recognizable thanks to their embossing. Our fabrics are available in different tensile strengths, with or without flame-retardant finish. Our products are constantly evolving to incorporate new developments. One of these is our “anti-browning” feature, which significantly reduces the brownish discoloration of the membranes in bio gas domes plants.

Supply of drinking water has highest priority in case of environmental disasters or other crisis. Flexible tanks guarantee quick supply and swift transport options for clean drinking water. SATTLER PRO-TEX membranes are certified according to the German ordinance on drinking water (KTW) and are approved for drinking water applications.

The sturdy membranes for industrial water by SATTLER PRO-TEX allow for manifold solutions to store and transport water in flexible tanks, be it for agricultural and industrial applications or in emergency situations. 

Applications in the field of ENVIRONMENT

Double membrane gas holders

Biogas is considered a sustainable and decentralized form of energy generation.

Self-supporting low-pressure storage systems made of double membranes are among the most efficient plant types: While the inner membrane stores the biogas, the outer membrane works as the outer shell. Since the construction is designed as an air-supported structure, it does not require a load-bearing element.
SATTLER PRO-TEX biogas membranes help to ensure minimal methane migration. Our products provide the highest functionality and reliability needed in this field of application.

Biogas Storage Systems in Mahape

Double membrane gas holders with placed roofs

Similar to the biogas holders, double membrane biogas roofs serve as storage space for digester gas, and are mounted onto an existing fermenter tank. A central pole supports the roof, which consists of both an outer membrane for weather protection and an inner membrane that seals the digester gas-tight.

SATTLER PRO-TEX biogas membranes offer the highest resistance to biogas components and the best protection against inclement weather.

Biogas roofs

Liquid manure, waste water tanks and silo containers do not usually spread pleasant smells, and should not be unnecessarily filled up with rainwater. Biogas roofs made of membranes are a highly efficient solution to both problems: the surroundings are shielded from smells to the greatest possible extent while the cover prevents rainwater infiltration. SATTLER PRO-TEX biogas membranes are also highly resistant to aggressive substances that can develop in the condensate.

Portable Shelter

Biogas bags

Inner membranes are used both to store the biogas in so-called double membrane gas holder, and also serve as housing for biogas bags mounted on buildings or steel or concrete tanks. SATTLER PRO-TEX biogas inner membranes are flexible and reliable functional fabrics, making them ideal for biogas storage applications.
