Liquid Hydrogen Dewar

Product Overview

The liquid hydrogen Dewar is a cryogenic container designed for the storage, transport, and distribution of liquid hydrogen. It features a systematic low-temperature insulation design to minimize hydrogen evaporation and losses during use.

This container balances safety, reliability, and operational convenience, making it ideal for medium- to short-term storage and mobile applications. It is suitable for hydrogen refueling stations, laboratories, research facilities, and various cryogenic engineering environments.

Working Principle

The liquid hydrogen Dewar uses an efficient vacuum-insulated structure, creating a high-vacuum space between the inner and outer vessels to effectively reduce heat conduction and convection.

Combined with vapor-cooled multi-layer shields and low-temperature condensation adsorption to maintain the vacuum, the system further reduces heat transfer from the environment, significantly lowering liquid hydrogen boil-off. This ensures stable low-temperature performance and safe storage and transport of hydrogen.
