Dewar 125L
Liquid storage capacity: 125 L • Design pressure: 4 barg • Nominal evaporation rate: 1.5%/day
The Dewar 125L is a dewar to store liquid hydrogen, designed for laboratory and experimental applications that require safe and efficient hydrogen storage. Its modular design allows integration with our liquid hydrogen transfer lines and bayonet couplings, enabling controlled hydrogen delivery to test systems.
Specifications
| Liquid storage capacity: 125 L | Filling supply pressure: 1.2 – 2.0 bara | Liquid transfer connection: DN8 bayonet |
| Dewar maximum filling rate: 12.5 g/s | Design pressure: 4 barg | Vent connection: Kenol 15C (1/2″ 10S) |
| Dewar minimum filling time: 12 min | Level indicator: Analog | Compliance: PED 2014/68/EU |
Electrical connections are not needed for the Dewar 125L, allowing use in ATEX zones without additional ATEX certification. An optional PLC-based control system can be added; when integrated, the complete assembly can be ATEX-certified.

Quality and safety testing
Our Dewar 125L are CE-marked and manufactured in full compliance with the EN-13445 standard for unfired pressure vessels, providing reliable pressurised hydrogen storage for laboratories and testing environments. Each unit is certified to PED 2014/68/EU and undergoes mandatory EC Unit Verification by an independent Notified Body, ensuring adherence to the EU’s safety regulations for hazardous fluids and high-pressure systems. To ensure operational integrity and safety, every Dewar 125L undergoes:
-
Functional product testing: Validation of system operability.
-
PED compliance tests: Verification of conformity with PED 2014/68/EU requirements.
-
Internal compliance tests: Integrity validation through helium leak detection and other internal assessments.
