PSA nitrogen generator offers a safe, convenient and energy saving method to produce nitrogen gas on site. Small or medium sized model can be mounted on one or several frames to achieve convenient installation.

Brief Working Principle
This product uses pressure swing adsorption technology to isolate nitrogen molecules from other molecules in compressed air, and the purity of nitrogen gas can reach up to 99.9995%. The core component is carbon molecular sieve, and it can adsorb oxygen while nitrogen is separated. Then, the adsorbed oxygen is desorbed and discharged during depressurization. So, continuous production of pure nitrogen is realized.

Working Process
The PSA nitrogen generator contains two adsorption towers that are filled with high quality carbon molecular sieve. At first, clean, dry and oil-free compressed air flows into one tower that is ready for adsorption stage, and when pressure increases, the efficient carbon molecular sieve inside prefers to adsorb oxygen molecules due to the different sizes of nitrogen and oxygen. As a result, nitrogen is separated and collected.

After a certain period of time, oxygen adsorption is under equilibrium. Carbon molecular sieve shows different gas adsorbing capacity under different pressures, so depressurization will be carried out to release adsorbed oxygen for regeneration process. At the same time, the other tower is pressurized, making it ready for work.

In this way, these two towers work in turn to obtain continuous nitrogen gas flow, and the nitrogen gas flows through nitrogen tank as well as flowmeter. After passing sample detection, nitrogen is ready for further use.

Features
1. High Reliability
This nitrogen generator adopts advanced nitrogen generation technique, and the unique flow distributor avoids air channeling. Hence, compressed air will flow through the adsorption bed with a more uniform speed, resulting in improved utilization rate of adsorbent.

The automatic clamp cylinder and unique air intake method guarantee that air inside the tower will flow in a constant direction, which is helpful to prevent fatigue wear of adsorbent. So, the life span of adsorbent is ensured. What is more, the key components are all provided by world famous suppliers. For example, the valves are extremely durable, and they can work for 1 million times, ensuring stable running of our machine.

2. Energy Saving Performance
The high performance carbon molecular sieve possesses extremely high dynamic adsorption capacity as well as excellent desorption property, so remarkable separation efficiency between oxygen and nitrogen is obtained. Moreover, the working flow is scientifically designed, and many measures are put into effect to recycle energy and materials. This not only improves nitrogen purity, but also saves a lot of energy which is more than 20% when compared with similar products.

3. Easy Operation
This PSA nitrogen generator is plug-and-play type, and it realizes automatic working. In addition, the nitrogen purity can be adjusted within 95%-99.9995% according to customer's needs.
