1. Air Compressor (Screw type): Air is used as raw material to collect & compress air to 8 bar.
2. Refrigerated Dryer: The standard configuration removes moisture and impurities in the air, so that the air dew point reaches -20°C
(the intermediate configuration uses an adsorption dryer, and the dew point reaches -40°C; the advanced configuration uses a combined dryer, and the dew point reaches- 60ºC).
3. Precision Filter: A/T/C three-stage filter to remove oil, dust and impurities.
4. Air buffer Tank: store pure and dry air for subsequent adsorption and separation of oxygen as raw material storage.
5. Adsorption Tower: A&B adsorption tower can work alternately, regenerating adsorption, filling sodium molecular sieve to filter out oxygen molecules.
6. Oxygen Analyzer: real-time monitoring and analysis of oxygen purity, indicating that the equipment is working normally and alarming.
7. Valves & Pipelines: Intelligent control valves realize automatic operation of equipment, PLC control, SUS304 pipelines.
8. Oxygen Buffer Tank: Store oxygen with qualified purity, which can be directly piped or used for bottle filling.
9. Oxygen Booster: Gas booster, pressurize the oxygen to the filling pressure, generally 150bar or 200bar.
10. Filling Manifold: split high-pressure oxygen & nitrogen into each gas cylinder.
