1. The requirement for raw argon is not high, the general bottled pure argon, liquid argon or better pipeline argon can be used;

2. High catalyst activity, large adsorption capacity, low working temperature, more energy saving equipment;

3. It is renewable, and can be used for a long time by repeated regeneration after failure;

4. Regeneration does not require hydrogen or vacuum, and a small amount of argon gas purified by the machine is used for regeneration, safe and reliable;

5. All valves are stainless steel bellows valves, almost no leakage;

6. For the double structure, one group works, the other group is regenerative and standby, continuous gas supply.
