Thermo-physical characterisation of materials down to 20 K for liquid hydrogen

Download the brochure

THEMACS Engineering markets a thermophysical property measurement bench dedicated to liquid hydrogen applications, operational down to 20 K.

This system enables the precise characterization of materials and components under cryogenic conditions (thermal conductivity, thermal resistance, associated behaviors), as close as possible to real-world conditions.

Designed for R&D and industry, this bench is intended for players in the storage, transport, and hydrogen technologies sectors who require reliability, traceability, and compliance with measurement standards.

Plaque chaude gardée à 20Kelvin

Leak test:

Leak tests on circuit components performed from 10 to 300K under hydrogen or helium pressure up to 200bar

Up to 3 pieces of equipment can be tested in the measurement area

Measurement area 200 m in diameter and 250 mm high

Leak detection threshold: 10-13 Pa.m3/s

Tensile tests:

30kN tensile testing machine for tensile tests. Thermal bridge breaker for rapid temperature reduction of the sample.

CTE measurement:

Measurement of expansion between 10 and 300K.

An option on the bench also allows for mechanical characterization under cryogenic conditions, including measurement of the modulus of elasticity, tensile strength, and coefficient of thermal expansion (CTE). These measurements down to 20 K provide a comprehensive understanding of material behavior for liquid hydrogen applications.
