Type I Steel Hydrogen Cylinders
Design & Construction
Manufactured entirely from high-strength steel, Type I cylinders are designed to ensure maximum durability under high-pressure conditions. Unlike composite alternatives, the all-steel construction provides superior mechanical durability and resistance to deformation.
- Material Integrity: Constructed using high-quality alloy steels (including SS-316 or Carbon Steel) specifically selected to minimize the risk of Hydrogen Induced Cracking (HIC) and surface embrittlement.
- Thermal & Fire Resistance: The steel structure maintains integrity under elevated temperatures and offers higher fire resistance compared to composite cylinders.
- Lifecycle Management: Cylinders can be periodically tested, inspected (via standard NDT methods), and recertified in accordance with international standards, ensuring a long service life.
- Sustainability: The units are 100% recyclable, supporting circular economy strategies.
Modular Bundle & Cascade Systems
System Architecture
For applications requiring higher volume capacities, Ergil offers Bundle Systems—a modular solution where multiple Type I cylinders are connected in parallel11. These systems are designed for ease of scalability and efficient space management.
- Integrated Manifold: Ensures homogeneous gas distribution and equal pressure across all cylinders, providing a continuous gas supply
- Configuration: Bundles typically range from 12 to 36 cylinders, offering a hydrogen storage capacity of up to ~46 kg per bundle.
- Fixed Cascade Systems: Ideal for stationary applications such as hospitals, laboratories, and industrial facilities. These systems connect cylinders in a series or staged layout to ensure uninterrupted flow for critical operations
- Safety Monitoring: Systems are equipped with pressure relief valves, leak detection, and continuous monitoring of pressure and temperature parameters.
