Detailed Description

Two process routes

Automatically regenerating adsorption type (BSS8-H, BSS5-A-H)

Adsorption vessels filled with custom material alternate between purification and regeneration modes for 24-hour uninterrupted supply. Regeneration is by heated purge using a mixture of purified gas and hydrogen — ambient purification, high-temperature regeneration. Maximum working pressure reaches 240 bar.

Getter type (BSS5-G-H, BSS9-G-H, BSS7-G-H)

Getter vessels filled with custom material operate at high temperature, removing impurities through an irreversible chemical reaction. High-temperature purification without regeneration, also rated to 240 bar.

Common features

・Comprehensive alarm, interlock and data logging functions ・Unattended automatic operation ・The adsorption type switches and regenerates automatically without interrupting supply ・The getter type covers THC and N₂ as well, which is exactly where the performance table differs

Selection guidance

Continuous supply required and a regeneration cycle acceptable → choose the automatically regenerating adsorption type. Deeper removal required (including N₂ and THC) with periodic getter vessel replacement acceptable → choose the getter type.

Processes and industries served

・High-pressure gas filling and repacking stations, raising source purity before filling cylinders ・High-pressure supply systems at gas companies: purification ahead of bundles and tube trailers ・High-pressure process equipment: certain annealing, sintering and pressurised chambers ・Research facilities and accelerators: high-pressure inert gas supply ・Hydrogen energy testing: quality control of high-pressure hydrogen

Installation and layout notes

・240 bar is the design pressure and the whole chain must match: fittings, valves, flexible hoses and safety valves must have no weak link ・Relief and discharge routing: high-pressure discharge releases considerable energy, so discharge direction and supports must be calculated ・A pressure-hold test is mandatory: pressurise with inert gas, hold, confirm no pressure drop, then introduce process gas ・Depressurise fully before any disassembly: confirm pressure at zero before loosening fittings — this is the most common source of accidents in high-pressure systems ・Allow space for getter replacement: plan the lifting and transport route for the getter vessel in advance ・Unattended operation depends on complete interlocks: alarms and interlocks must be tested item by item before automatic operation is commissioned ・The gas dictates additional rules: the hydrogen model (BSS7-G-H) is also subject to combustible gas regulations

Maintenance and regeneration

・Adsorption type: regeneration is scheduled automatically by the system, using a heated purge of purified gas mixed with hydrogen ・Getter type: cannot be regenerated, so the getter vessel is replaced once saturated, at an interval set by the impurity load of the source gas ・Recommended annual checks for high-pressure systems: safety valve calibration, pressure vessel inspection, and the condition of fittings and gaskets ・The data logging function allows the operating history to be reviewed and is an important basis for judging replacement timing

Frequently asked questions

Are 240 bar and 24 MPa the same thing?

Yes, only the unit differs (1 MPa ≈ 10 bar). Both appear in specifications and refer to the same pressure rating.

Why is the flow only 100 Nm³/h?

The wall thickness of a high-pressure vessel limits the effective bed cross-section, and the safety design at high pressure takes up further usable space. Where more gas is needed, common practice is to reduce pressure first and use an ambient-pressure purifier, or to manifold several sets in parallel.

Regeneration uses hydrogen — is that a safety concern?

The regeneration purge uses a mixture of purified gas and hydrogen, with both quantity and concentration within the design envelope and monitored by interlocks and detection. The site still needs ventilation and detection to combustible gas rules, and that has to be confirmed at the layout stage.
