    Gas tank with maximum volume: 75% Double Membrane Gas Storage

    The AGROTEL 75% Double Membrane Gas Storage is the perfect solution for efficient gas storage. Very large volumes can be realised with low acquisition costs.

    External spherical gas storage

    We plan and develop the gas storage individually in accordance with your wishes and local conditions. The 75% Double Membrane Gas Storage consists of an outer, inner and a bottom membrane. The gas space is formed between the inner membrane and the bottom membrane.

    High snow and wind stability

    The interaction of high-quality materials ensures maximum stability.

    High economic efficiency

    Very large volumes can be realised even with low investment and maintenance costs.

    High operating reliability

    Selected material components and integrated safety devices (e.g. over pressure valve, blow off pipe) guarantee the safety of the plant and avoid downtimes.

    High frequency welded PVC-membrane

    Our technical textiles are high-frequency welded per DIN 18204-1. During the welding process, the highest temperature is applied directly at the seam, creating an optimal bond. Metal components made of stainless steel

    Metal components made of stainless steel

    All metal components such as centre support, screw connection and fastening technology are made of corrosion-resistant stainless steel.


    For our gas storage solutions we use technical textiles that are UV-stable, weatherproof, gas-resistant and anti-mould treated.

    Fabric types in accordance with requirements

    Our high-quality technical membranes are selected in accordance with static and operational requirements.

    Flame retardant

    Our technical textiles are flame retardant (B1) and non-dripping.

    High working pressures

    The high stability of the PVC-membrane allows operating pressures up to 50 mbar.
