HYVOLUTION – Paris 2024

For the second year, Covess participated in Hyvolution show in Paris.

Covess displayed a 330 L Type 4.5 Cylinder cut in half. It was the opportunity to show a perfect melt between the liner and the Tape i.e. that with their process; they can achieve a monolithic composite structure as expected. Therefore, Covess proved that their composite technology end up with a monolithic structure that paves the way to the possibility to do vacuum in such a cylinder to comply with efficient decontamination of a cylinder before it is filled with Hydrogen (to meet the target of less than 5 ppm of water in Hydrogen).

When discussing with visitors and more specifically cylinder manufacturers, a monolithic composite structure is seen as a clear advantage compared to traditional Type IV cylinders. Especially to meet usages (drying / decontamination).
