Wire mesh for H₂ process technology
In the field of hydrogen technology, highly specialised components play a central role in ensuring safe and efficient processes. Whether as a backing cloth for membranes, explosion protection in Ex zones or support fabric for catalysts, wire mesh from Haver & Boecker offers precisely tailored solutions for demanding uses.
Backing cloth for membranes
Membranes are essential components for hydrogen separation and compression. To increase their mechanical stability and extend their service life, highly permeable backing cloths are used. Wire mesh offers multiple benefits in this regard:
- Optimised flow properties for maximum efficiency
- Different weave types and pre-treatment options for increasing the seat
- Increased pressure stability and rigidity of the membrane
Explosion protection in Ex zones
Gases have to be safely expelled from potentially explosive atmospheres without sparks or flames being able to spread. Specially developed wire meshes offer effective protection here:
- Targeted gas flow turbulence: multi-layered mesh elements create controlled flow effects that promote uniform gas distribution and avoid localised concentration peaks.
- Diffusion-based concentration balancing: the fine pores in the mesh enable a slow and uniform gas exchange with the environment, preventing explosive mixtures from accumulating.
- Effective spark and flame arresters: defined mesh structures ensure that sparks and flames are unable to escape.
- Robust and durable materials: special materials and coatings provide high temperature and corrosion resistance, even under extreme conditions.
- Proven technology from the electronics industry: our wire meshes have been successfully used as safety components in sensitive applications for decades.
Wire Mesh for biomethanation
CO₂-neutral methane production is a key approach on the path to a sustainable circular economy. Using specialized microorganisms, carbon dioxide and hydrogen can be converted into methane – a versatile energy carrier for synthetic fuels (e-fuels), gas power plants, or heating systems.
How does biomethanation work?
A synthetic fleece serving as a carrier material for the methane-producing microorganisms is stretched over a hollow wire mesh support element. This setup forms the necessary stable and permeable framework.
To maintain the biofilm over time, the fleece must be continuously moistened. The wire mesh serves a dual purpose: it provides mechanical support for the fleece and enables even distribution of process water. The water is directed between the layers to ensure the required humidity. Hydrogen and CO/CO₂ are supplied from the outside. The resulting methane accumulates on the inner side of the mesh element and is extracted through a dedicated gas pipe.
Advantages of wire mesh in biomethanation
Stable structure with high permeability
The wire mesh offers ideal mechanical support for the fleece while ensuring uniform flow-through.
Even pore distribution
Precisely manufactured mesh structures enable consistent distribution of process water and enhance methane production efficiency.
Customizable mesh design
Haver & Boecker can tailor the mesh to balance moisture supply, internal gas collection, and overall system efficiency.
Individual consultation and design variety
Depending on system requirements and desired flow characteristics, Haver & Boecker provides comprehensive advice on suitable mesh variants.
Support fabric for catalysts
Catalysts work best when they are optimally positioned and kept stable. Our highly porous, fine meshes reliably secure fine grains in place and ensure high chemical resistance.
- Special mesh configurations for different catalyst materials
- Chemically stable special materials such as Inconel 600, Hastelloy C22, titanium or nickel alloys
- Individual shape adjustment: blanks, deep-drawn segments, pleated structures and much more
