FAQ – H2 products
What you need to know
If you have any further questions, please do not hesitate to contact our customer service team.
What does DILO Hydrogen do?
DILO Hydrogen develops components, devices and bespoke solutions for the safe and controlled handling of hydrogen. Our portfolio covers key tasks such as pipe connections, filling, commissioning, and devices for the servicing and maintenance of H₂ systems. In doing so, we apply the DILO Group’s decades of experience in safe gas handling to the specific requirements of hydrogen applications.
What H₂ products does DILO Hydrogen offer?
DILO Hydrogen’s current portfolio includes:
- high-pressure pipe connections with pure metal seals,
- bespoke piping,
- H₂ distribution systems,
- the mobile and portable H₂ Service & Commissioning Units
- the Smart Hydrogen Refuelling System.
We determine which solution is suitable based on your application, the technical interfaces and the on-site operating conditions.
How does the H₂ Service & Commissioning Unit assist with service work?
The H₂ Service & Commissioning Unit supports key work steps during the servicing, maintenance and commissioning of hydrogen systems. These include:
- controlled pressure relief,
- inerting with nitrogen,
- measurement of the residual hydrogen concentration,
- purging with forming gas in preparation for a leak test.
- leak test using the pressure drop method
Automated procedures enable the individual process steps to be carried out in a controlled and traceable manner. The specific scope of functions depends on the respective unit model and its technical operating limits.
When is the portable H₂ Service & Commissioning Unit appropriate?
The portable H₂ Service & Commissioning Unit is suitable for mobile service, maintenance and commissioning work at varying sites (of operation / of use / of installation). It is particularly useful when the required functions need to be provided directly at the hydrogen plant. When selecting the unit, we take into account the required range of functions, the available connections, the gas supply and the conditions at the site (of operation / of use / of installation).
How does the Smart Hydrogen Refuelling System work?
The Smart Hydrogen Refuelling System enables refuelling with gaseous hydrogen from up to four connected storage tanks. Refuelling takes place via an automated cascade process. Depending on the available storage pressure and the respective operating conditions, refuelling up to a maximum of 350 bar is possible. The actual refuelling volume achievable and the final pressure depend on the specific application.
What is important when it comes to unions and piping for hydrogen?
Unions and piping for hydrogen must be tailored to the pressure, temperature, installation situation, materials and the adjacent system components. DILO Hydrogen offers all-metal sealing high-pressure pipe unions as well as customised piping for this purpose. The permissible pressure and temperature ranges depend on the specific design and are determined on a case-by-case basis.
How does DILO Hydrogen integrate its solutions into existing processes?
We consider not only the individual product, but also its connections and the process steps before and after it. Together with the customer, we clarify how filling, servicing or maintenance should be carried out at the site (of operation / of use / of installation). This enables components and devices to be selected to suit the existing interfaces and operational requirements.
What information is helpful for a product enquiry?
For a targeted technical assessment, we require the following information where possible:
- Description of the application,
- Desired task, for example filling, commissioning or maintenance,
- Hydrogen state and gas quality,
- Pressure and temperature range,
- Existing connections and interfaces,
- Site (of operation / of use / of installation), and environmental conditions,
- Desired process sequence,
- any specific technical or regulatory requirements.
On this basis, we can work with you to determine the most suitable design.
