VSA (Vacuum Swing Adsorption) belongs to a form of PSA (pressure swing adsorption). No oil handling system, high pressure vessels and multiple valve sets are required, greatly simplifying the equipment structure. A single oil-free intelligent rotating assembly can generate positive and negative pressure. It is a highly integrated system that is more energy efficient, efficient, reliable, has a smaller footprint, is easy to install and easy to maintain.
VSA (Vacuum Swing Adsorption, vacuum desorption pressure swing adsorption) oxygen generator components usually include:
6. Air handling unit: involves primary air filtration, air compression, cooling, water removal, nitrogen discharge.
7. Nitrogen and oxygen separation unit (oxygen generator) : Through the adsorption tower molecular sieve to complete the separation of nitrogen and oxygen, to obtain oxygen
8. Oxygen treatment unit: deodorize and sterilize the obtained oxygen, and then pressurize the oxygen directly to the user for use or storage in the oxygen tank.
9. Intelligent control system: monitor, record and analyze various operating parameters of the entire system. It also provides automatic adjustment, automatic exception diagnosis and alarm notification, maintenance reminders and message sending.
Compared with PSA technology, VSA does not require pressure vessels and oil treatment systems, only three core components, the overall structural design is very simple, scientific and reasonable, improve the reliability of the equipment. Easy to save energy, maintenance, installation, extend the service life of the equipment.
Compared with PSA oxygen generator (molecular sieve pressure Swing Adsorption), VSA oxygen generator (Vacuum Swing Adsorption) has a very simple structure, consisting of only 3 key components, and uses a single oil-free intelligent component to provide positive and negative pressure. Overall, VSA offers 10 significant benefits:
1. Minimal structure: VSA is highly streamlined, with only three main components - air compressor, oxygen generator and oxygen compressor. This simplicity minimizes maintenance efforts and costs, optimizes process flow, has excellent reliability and higher efficiency.
2. Energy saving: The system operates under low pressure to reduce energy consumption, and the minimalist structure further reduces energy loss. This makes the VSA very energy efficient.
3. Quick installation: The three main components are integrated and modular in design, allowing for quick and easy installation.
4. Highly intelligent: The system can automatically adjust the operating parameters according to the environmental conditions, working frequency and use habits. It can also predict and handle anomalies and maintenance needs, ensuring equipment is operating at peak efficiency. This reduces the cost and complexity of hospital administration and ensures efficiency, longevity and safety.
5. Low pressure operation: the air pressure is lower than 0.1MPa, and the molecular sieve adsorption pressure is also lower than 0.1MPa (about one-tenth of the traditional PSA pressure). This low-pressure environment minimizes the risk of molecular sieve crushing.
6. Oil-free oxygen production: The compressed air obtained is oil-free, preventing molecular sieve oil pollution. It also saves maintenance costs from oil treatment.
7. Extend the life of molecular sieve: the life of molecular sieve is affected by water, oil and pressure. VSA addresses these three factors, reducing the risk of sieving, oil contamination and water softening failure of the molecular sieve.
8. No pressure vessel required: This makes operation and management easier and safer.
9. Environmental protection: The entire system does not require oil treatment system, oxygen is not polluted by oil, and the final product is oil-free, ensuring safe and clean oxygen use. This also contributes to environmental sustainability.
10. Low use cost: low energy consumption in system operation, and 40% reduction in unit oxygen production cost. Management costs reduced by 50%. Annual maintenance costs can be saved by more than 60%.
Together, these features demonstrate the excellence of VSA oxygen generators in terms of energy saving, efficiency, reliability, installation, cost effectiveness and safety.
