Hexagon Purus (Oslo, Norway) is displaying its broad portfolio of composite-overwrapped pressure vessels (COPVs). The primary focus is on its Type 3 (metallic liner) and Type 4 (plastic liner) COPVs developed and qualified for the aerospace and automotive industries. Hexagon Purus’ team is available at the booth to discuss its solutions.

These cylinders are said to be lightweight, cost-effective and reliable. The company offers propellant and pressurant tanks up to 10,000 psi operating pressure and 1,000 L water volumes in a variety of mounting configurations. Custom designs are possible or an existing design can be tailored to meet the customer’s specific requirements. Cylinders can be certified to industry standards such as AIAA S-081 or G-082 or to customer-specific requirements.

Hexagon Purus’ Type 4 cylinders are designed to present several advantages in modern aerospace applications including rapid development cycles, reduced weight and fatigue resistance. They can be used in many pressurant applications and with krypton and xenon in electric ion propulsion systems. The cylinders have completed rigorous qualification test programs and have met vibration, static loading, thermal, damage tolerance, lifecycle and rupture test requirements.

Also featured are the company’s Type 4 hydrogen mobility cylinders and storage systems, which are commonly used in fuel cell electric buses and heavy-duty trucks. Cylinders operating at 350 and 700 bar are typical with hydrogen capacities up to 18 kg. Storage systems can be offered in roof mount, behind-the-cab (BTC) or sidemount configurations with capacities up to 74 kg. These systems can be supplied with the necessary refueling receptacle, filtration, regulator, high- and low-pressure gages, relief valves and controller for a completely integrated solution.
