Vessels solution for Biogas production plants
Plant start-up in 24 h with an 18% lead-time reduction
Crainox has built—and continues to build—plant components for producing biogas, gas turbines, and multi-compartment tanks. Biogas is a mixture primarily of methane (CH₄) and carbon dioxide (CO₂) generated by the anaerobic digestion of organic matter (agricultural waste, slurry, food waste, etc.). It can be used to produce electricity and heat, or upgraded to biomethane for injection into the gas grid or for use as a fuel. In particular, we wish to highlight our strong capability in manufacturing medium-to-large tanks with PED certification, fully industrialized and/or designed and managed within the company’s entire value chain.

Realise your projects, find the answers to your questions
A single partner for bespoke stainless steel solutions
Every project has different requirements. Whether it’s pressure vessels, skids, or stainless steel structures, the Crainox team is available to analyze your request and develop the most suitable solution together.
Realise your project with usA Crainox Project Leader coordinates technical reviews with the EPC team, manages documentation, and serves as the single point of contact until completion of FAT/SAT testing.
We have two dedicated vehicles for rapid deliveries within Europe and a network of freight forwarders for international shipments. We offer seaworthy packaging and full handling of customs formalities.
The 3.1 is issued by the steel manufacturer; the 3.2 involves verification by a third-party body certifying the material’s conformity with the PED dossier.
Components and systems are pre-wired and tested in the workshop. “Plug-and-play” delivery minimizes on-site interventions and the related HSE risks.
