External biogas storage: Reliable intermediate storage for biogas
At AGROTEL, we offer you customised and reliable external gas storage solutions that are precisely tailored to your needs and meet the highest quality standards.
External gas bag: Flexible intermediate storage for biogas
The external gas bag from AGROTEL CenoTec is a gas storage bag that can be customised in terms of shape, size and volume to meet the customer’s specific requirements. It is used for intermediate gas storage during conversion work or repairs to biogas plants.
Increased economic efficiency
A mobile intermediate storage unit prevents restrictions in system operation.
Environmental protection
A reliable, temporary storage system prevents the release of biogas or methane into the environment.
Increased operational safety
The mobile gas storage unit enables the CHP unit to be operated even during overhauls or conversions.
Mobile gas storage systems: Gas bags
Gas bags from AGROTEL Ceno Tec can be manufactured as cylinders or rectangular cushions. This unpressurised gas storage system is installed in buildings or in steel or concrete containers.
The non-pressurised gas bags are usually extracted and filled via connections in the non-moving floor and ceiling surfaces. Rope length measuring systems are used to measure the filling level. Gas bags require an enclosure to absorb external loads.
Mobile gas storage systems: gas bags in detail
Flexible and space-saving solution
Gas bags from AGROTEL Ceno Tec can be manufactured as cylinders or rectangular cushions. The cylindrical or cushion-shaped design enables space-saving integration into existing buildings or containers made of steel or concrete.
Unpressurised gas storage
In contrast to pressurised containers, gas bags work with an unpressurised system. Gas is extracted and filled via connections in the floor and ceiling area. This ensures simple and safe handling.
Continuous level control
Rope length measuring systems are used to keep an eye on the fill level of the gas bag at all times. This technology enables precise monitoring of the gas supply.
Robust construction for high loads
AGROTEL gas bags are made from high-quality materials and are designed to withstand external loads. An enclosure provides additional protection and stability.

High tear resistance
The very good weld seam adhesion, guarantees optimum surface stability for the membrane.
Flame retardant
Our technical textiles are flame retardant (B1 per DIN 4102 (B1, S2, d0) and EN 13501-1) and non-dripping.
Special membrane
Gas Storage Tanks are made of a special membrane. The technical textile is a polyester fabric with a plastic coating on both sides and acrylic paint.
Weatherproof
For our external gas storage tanks, we use technical textiles that are UV-stable, gas-resistant and anti-mould treated.
Surface weight 830 g/m²
The robust fabric tarpaulin is ideally suited to long-term use. It is absolutely waterproof durable and cleanable.
High-frequency welding
The precise welding technique ensures optimum leak-tightness, which is tested before every delivery.
