Industrial And Hospital PSA Oxygen Generator System CE / ISO / Approved

PSA (Pressure Swing Adsorption) Technology is a revolution in Non-Cryogenic Air Separation and Oxygen Generation Technology using a special grade of ZMS (Zeolite Molecular Sieve).

The compressed air is passed through a Twin Tower PSA module interconnected with automatic changeover valves. After passing through a Refrigerated Dryer, air gets dried. Dried compressed air will now come in contact with the bed of Zeolite molecular sieves (ZMS). Zeolite Molecular Sieves are a special grade of adsorbent that has the property of preferential adsorption of nitrogen molecules.

At a time one tower remains under the nitrogen production cycle, whereas the other tower undergoes regeneration which is achieved through depressurization of the tower to atmospheric pressure. The outgoing oxygen gas is sent to a surge vessel where the minimum pressure will be maintained with the help of a Backpressure Regulator.

The traditional methods of making oxygen need to cool air into liquid (about -180℃), via exacting to get oxygen. PSA oxygen generator under normal temperature, and normal pressure working, had the following advantages:

• Lower cost: PSA oxygen system choosing special ZMS CMS and advanced technical design make the plant lower investments, lower consumption, compared to another oxygen system little maintenance, etc characteristics.
• Simple flow sheet: Automatic level, operation easily.
• Compact design: Compared to air separation, which needs a small area, a perfect constructor, safe area, it can be used both outdoors and indoors.
• Quick operation: Oxygen can be supplied within 5 minutes, shut convenient, can operate easily, the system will control automatically fully, no need for workers on duty.
• Safe operation: Working under normal temperatures, and lower pressure, the whole recovering process does no need heating, it is safe.
• Adjustable output: The oxygen purity and capacity can adjust easily, strong adaption, oxygen purity (30%-93%), and purity can control, while the oxygen capacity or purity down can greatly save energy.
• Advanced filtration: Super filter protective system reduces the pollution for ZMS CMS, advanced molecular sieves compressed technology reduces sieves pulverization, and bed down reduce function.

• Capacity: 2~150 Nm3/h
• Purity: 92±2%
• Initial Pressure: 0.05~0.4 Mpa
• Dew point: -65℃

• Full Automation: All systems are designed for unattended operation and automatic Oxygen demand adjustment.
• Lower Space Requirement: The design and Instrumentation make the plant size very compact, assembly on skids, prefabricated and supplied from the factory.
• Fast Start-up: The start-up time is about 30 minutes to get desired Oxygen purity. So these units can be switched ON & OFF as per Oxygen demand changes.
• High Reliability: It's very reliable for continuous and steady operation with constant Oxygen purity. Plant availability time is better than 93% always.
• Long Sieve Life: Expected Zeolite Molecular Sieves life is more than 10 years i.e. whole lifetime of the Oxygen plant. So no replacement costs.
• Cost Effective: Low investment and energy consumption.
• Easy Maintenance: Simple operation and maintenance.

• After the oxygen generator, the oxygen purification system is equipped to guarantee the quality of the O2 and remove dust, eliminate bacteria, and stabilize pressure to ensure the oxygen outputted stably and meets medical standards.
• Users only need to turn the start/stop button to gain oxygen with designing the required flow capacity and purity within 30 minutes.
• Single line and double line types are available for option. Users are suggested to choose the single line type when they only require a stable flow capacity; choose double lines when demand is unstable and sometimes meet extra peak values.
