Proof Pressure Test Stand for Hydrogen Composite Pressure Vessels

• For vessels up to 600L with test pressure up to 1050 bar
• Cycle time about 10-180min. (depending on vessel volume)
• Fully automatic process with swivel fixture
• Loading either manually or automatic
• 100% water as test fluid
• Including filling, pressurization and draining process


The use case of the Maximator VETEQ proof pressure test stand is the proof test at the end of the production process of hydrogen composite pressure vessels. National and international regulations as well as customer specifications mandate end-of-line proof pressure testing to ensure strength and safety of every vessel. The proof test is performed with water and includes an automatic filling and draining process. Moreover, the required expansion measurement is performed with an intelligent scaling process which is CGA approved.

The Maximator VETEQ proof pressure test stand is divided into 3 sizes to fit all commonly produced vessel sizes. Based on the vessel dimensions and later application, customers can configure the proven modular design in the sizes S, M or L. The chart afterwards shows the delimitations between these 3 different sizes.
