Membranes
Our weather protection membrane made of PVC-coated polyester fabric impresses with its high tear resistance, UV and weather resistance and TRAS120 conformity. Customised handwork and two independent welding processes guarantee double safety.
The advanced latest generation of environmentally friendly gas storage membranes made of PE is characterised by high flexibility, low permeability and a significant reduction in odour emissions.
Heat protection membrane
Our patented heat protection membrane prevents the constant upward movement of the gas and thus reduces heat losses by up to 30 %. The gas storage volume remains fully usable, saving energy and costs, which pays off quickly and is environmentally friendly.
Substructure
Our belt net substructure combines reliability and durability: the substructure is decoupled from the mounting system, which not only offers flexibility but also safety during maintenance and installation work. The function of the substructure is retained even after the membrane has been opened. The robust substructure net prevents direct contact between the membrane and the substrate. High-quality V4A stainless steel parts and biogas-resistant materials guarantee maximum service life.
Fastening system
Thanks to its special design, the Baur double flat profile made of stainless steel is the right solution for every container. This design ensures optimum gas tightness, offers high stability and durability. Thanks to replaceable screw anchors, it is maintenance-friendly and cost-saving.
The Baur stainless steel U-profile with clamping hose system offers a safe, maintenance-friendly and durable solution for foil fastening. The dual-circuit system enables fast opening and closing, while the integrated compressed air monitoring ensures optimum operational safety. Thanks to the addition of glycol, the system remains frost-proof and reliable even at low temperatures.
Supply and exhaust air system
Our ATEX-certified support air blowers offer the perfect solution for the optimum operation of your double membrane gas storage tank. We plan the design of the support air supply individually according to the requirements of your biogas plant. Thanks to our extensive stockholding, we guarantee the rapid availability of various blower types.
Our supply and exhaust air system ensures safety and efficiency in your double membrane gas storage tank. They enable precise adjustment of the support air pressure and compensate for pressure changes.
Measurement technology
For efficient system control, we integrate the appropriate measurement technology for your gas storage system. We offer the following gas level measurement variants with a signal range of 4-20 mA:
- Level measurement with cable system and level measuring rod
- Level measurement with laser sensor
- Level measurement with hydrostatic sensor
Overpressure and underpressure protection
Our overpressure and underpressure protection based on the immersion cup principle reliably protects your double diaphragm gas cylinder. We offer various versions for different operating pressures and volume flows. An optionally available trace heating and signalling of the overpressure for safe, trouble-free operation.
Centre support
We offer V4A centre supports, centre support extensions or customised head parts for concreted centre supports or wooden supports - flexible and a perfect fit for your double membrane gas storage tank. Stability and quality from a single source!
Belt tensioning
Our patented belt tensioning system specifically relieves the weather protection membrane by absorbing additional loads and distributing them evenly. The arrangement of the belts specifically reduces the load on the membrane at the key points, which significantly increases the stability of the gas holder under increased wind loads and higher operating pressures. This leads to improved operational safety and higher efficiency.
Service opening
Our specially developed service opening for double diaphragm gas storage tanks enables quick access to the support air space for maintenance work and inspections, regardless of the weather. It is not necessary to open the diaphragm fastening system.
