Optimizing the balance between product performance, investment in equipment
and operational cost.

We deliver type IV pressure vessels for storage of CNG, biogas and hydrogen at production sites, such as electrolysis at windmills or solar / biogas plants, as well as at consumption sites, such as industrial plants or filling stations.

UAC pressure vessels are delivered with plastic liner, stainless steel endbosses and composite structure, made of high-strength, lightweight fibreglass and epoxy resin. Non-toxic and non-corrosive properties of our pressure vessels benefit the lifetime of storage solutions by eliminating risk of galvanic oxidization. Weight savings, temperature tolerances, long-term design life and enhanced safety levels offered by glass fibre pressure vessels challenge alternative solutions in steel or other composite materials. Glass fiber pressure vessels are also a much more price competitive alternative, compared to carbon fiber cylinders.
