ULTRESSA is an ultralight pressure cylinder with a structure in which a seamless cylinder (liner) made of metal such as aluminum alloy or resin is used as an inner cylinder, and the outer side is wrapped in multiple layers with high-strength fibers such as carbon fiber impregnated with epoxy resin and glass fiber. In the worst case scenario, to avoid a rupture, the liner would allow the gas inside to leak first, to safely lower the internal pressure within a specially designed structure (Leak Before Break structure).

1. 1.Light weight - Approx. 1/3 of the weight of a steel container (Aluminum Type 3 containers)
2. 2.Safety - High strength fiber and Leak Before Break structure
3. 3.Anti-corrosion - Corrosion-resistant treatment on the inner surface (inside the container)
4. 4.Large dimensions - 300-liter containers have been granted approval from Japanese authorities; development underway for even larger capacity
5. 5.High pressure - 70MPa containers have been sold; 100MPa has been prototyped
6. 6.Track record - A stable sales track record of more than 35 years

■Contributing to the reduction of CO₂ as global warming countermeasures
■Working hard in the background to support our hydrogen society
■Contributing with FRP composite pressure vessels required in “transport,” “storage,” and “use” applications

With our lineup ranging from small to large, ULTRESSA will play an active role in various phases such as "transport," "storage," and "use" in a hydrogen society. We can also provide assistance in responses to laws and regulations; Please contact us for details.

ULTRESSA is also used extensively in the aerospace and industrial robotics fields.
Filled with gas such as helium and nitrogen, our vessels have also been successfully installed in rockets and artificial satellites.
