Cost Saving VSA Oxygen Generator / VSA Oxygen Plant For Medical 93% Purity
Why is VSA used for oxygen production in the pharmaceutical industry? What are its core advantages?
In the field of medicine, especially in hospitals, the requirements for oxygen are extremely strict: it must be continuously stable, pure and safe, and have sufficient supply. Compared with traditional oxygen supply methods (such as cylinder oxygen, liquid oxygen) and other oxygen production technologies, VSA oxygen production has the following significant advantages:
1. Significant economic advantage (cost reduction)
This is the most core and attractive advantage of VSA oxygen production.
Compared with traditional methods, the cost of long-term use of steel cylinder oxygen or purchased liquid oxygen is very high, including gas costs, transportation costs, rent, and management fees. Once the hospital's oxygen consumption increases, this expenditure will be very staggering. VSA oxygen concentrators only require electricity consumption and minimal maintenance costs. The initial investment payback period is usually short (1-3 years), and the cost of oxygen is almost only equivalent to electricity. In the long run, it can save 40% -60% or even more oxygen costs.
Compared with other oxygen production technologies, VSA requires lower working pressure (usually less than 0.5 barg) due to desorption under vacuum conditions, while traditional PSA requires higher pressure (4-8 barg). The lower the pressure, the lower the energy consumption of the air compressor, so VSA is usually more energy-efficient and has lower operating costs than traditional PSA oxygen production.
2. Excellent reliability and continuity (ensuring safety)
Medical oxygen supply is the lifeline and must not be interrupted.
Self sufficiency and independence: After the hospital has its own VSA oxygen production system, it is no longer affected by external supplier transportation, weather, market fluctuations, and other factors, achieving "self-sufficiency" in oxygen and greatly improving supply chain security.
Multi level guarantee design: Standard VSA medical oxygen production systems typically adopt modular design (multiple units in parallel) and built-in backup systems. Even if one unit undergoes maintenance or malfunctions, other units can automatically increase production to ensure uninterrupted oxygen supply. The system will also automatically monitor oxygen purity, pressure, and flow rate. Once there is an abnormality, it will immediately sound an alarm and automatically switch to the backup liquid oxygen or cylinder oxygen system, forming a seamless connection.
3. Pure and safe oxygen, in compliance with pharmacopoeia standards
Medical oxygen has strict purity standards (usually ≥ 93%, according to the Chinese Pharmacopoeia, ≥ 99.5%). The oxygen purity produced by VSA oxygen concentrators can remain stable within the range of 93% ± 3%, fully meeting the vast majority of medical applications such as respiratory support, surgical anesthesia, ICU, etc.
The system is equipped with precision filtering and monitoring devices to ensure that the produced oxygen is sterile, free of impurities, and harmful gases, in compliance with GMP (Good Manufacturing Practice) and pharmacopoeia requirements.
4. Easy to operate and highly intelligent
The modern VSA oxygen production system is fully automated by an intelligent control system (PLC) and can achieve unmanned operation. The system automatically starts and stops, adjusts production to adapt to changes in terminal oxygen consumption, records operational data and alarm information.
Greatly reducing the tedious work and safety hazards of managing gas cylinders and switching bottle groups for medical staff.
5. Flexibility and Scalability
Modular design allows hospitals to configure according to current needs and future development plans. In the initial stage, basic modules can be installed first. With the expansion of hospital beds, simply adding oxygen modules can easily expand the capacity, which is very flexible.
6. Environmentally friendly
Reducing the carbon emissions generated during the manufacturing of steel cylinders and transportation of liquid oxygen, the energy consumption is also lower, which is more in line with the development concept of green hospitals.
