Evaluate non-metallic valve seals under low-temperature, high-pressure hydrogen conditions with our Precooled Hydrogen Exposure Test System.
The equipment is intended primarily for seals used in combination valves on vehicle hydrogen storage cylinders. It supports the assessment of hydrogen compatibility, durability, and sealing reliability within an agreed test programme.
Manual and automatic control modes allow users to select the approach suited to their work. During automatic testing, the control system collects parameters, generates pressure curves, and produces printable test reports.
Turn Exposure Tests into Recorded Results
For valve manufacturers and testing laboratories, test records need to connect the specimen with its actual exposure conditions.
The automatic control system manages the test process and records the selected parameters. Pressure curves provide a visual record of pressure behaviour, while printable reports support technical review and project documentation.
Manual control is also included. Therefore, the control method can be selected according to the test task and approved operating procedure.
Before ordering, define the required test sequence, recorded channels, report fields, and acceptance criteria. This helps align the equipment configuration with the intended evaluation.

Assess Seals for Vehicle Hydrogen Storage Valves
The primary application is exposure testing of non-metallic seals used in high-pressure hydrogen cylinder combination valves.
For component development, specify the seal material, specimen arrangement, and exposure requirements. For valve-level testing, provide the assembly drawing and connection details.
The equipment information also identifies research institutes, new-energy businesses, metallurgy, and mining as application sectors. Suitability depends on the actual specimen and test programme.
A complete inquiry should explain what the test must demonstrate. In addition, identify whether the assessment concerns material compatibility, durability, sealing performance, or a combination of these objectives.
Defined Materials and Pressure-System Components
The supplied configuration specifies 316L stainless steel pipework with nickel content of at least 12%.
It also identifies SPIR STAR tubing and valves for the pressure-control system and IHT high-pressure pumps. These component references provide a basis for reviewing the proposed bill of materials.
During procurement, confirm the included components, fluid interfaces, material documentation, and operating limits. For replacement or repeat orders, reference the agreed configuration and identify any changes to the test conditions.

Hydrogen Monitoring and Ventilation Features
The listed configuration includes an automatic detection and alarm system, together with an automatically controlled explosion-protected ventilation fan.
The hydrogen detector has a stated measuring range of 0–100% LEL. This should remain distinct from the hydrogen purity specification in technical documents.
The product information also lists Ex d IIC T6. Confirm which components this designation covers and request the applicable supporting documentation during quotation.
Alarm functions, ventilation control, and site interfaces should be defined as part of the complete installation scope.
Agree the Test Method and Acceptance Requirements
The supplied reference list includes GB/T 42536-2023, covering assembly valves for high-pressure vehicle hydrogen storage cylinders.
For a purchasing specification, identify the applicable standard, edition, test clauses, and acceptance criteria. Also, define the required specimen conditions and evidence to be recorded.
A standards reference does not, by itself, establish certification of the complete test system. Agree the required inspection, calibration, functional verification, and documentation scope before placing the order.
