Nitrogen Generator System for Laser Cutting
A nitrogen generator system for laser cutting is a type of system used to provide high-purity nitrogen gas for laser cutting machines. Laser cutting is a process that uses a high-power laser beam to cut or engrave various materials, such as metals, plastics, and wood. Nitrogen gas is often used as a cutting gas during the laser cutting process, as it helps to remove the molten material and prevents oxidation, resulting in a clean and smooth cut.
A nitrogen generator system for laser cutting typically consists of a PSA (Pressure Swing Adsorption) nitrogen generator, a storage tank, and a distribution system. The PSA nitrogen generator produces high-purity nitrogen gas by removing other gases, such as oxygen, from the compressed air using adsorption technology. The nitrogen gas is then stored in a tank and distributed to the laser cutting machine through a pipeline.
The Advantage of our Nitrogen generator
Molecular sieve is the most important part of the nitrogen generator and plays a key adsorption role.The adsorption tower of our company's pressure swing adsorption nitrogen production device adopts a composite bed structure design, which has the advantages of ensuring the service life of the carbon molecular sieve and improving the nitrogen production rate of the carbon molecular sieve.

| 1 | Adopting a composite bed structure with a reasonable distribution of alumina, brown pads, molecular sieves, etc. | Single-bed structure with molecular sieves filled directly. |
| 2 | When in contact with carbon molecular sieves, the compressed air dew point at atmospheric pressure reaches below -48°C, with a moisture content of only 0.075g/m³. The water absorption of the carbon molecular sieves is minimal. | When in contact with carbon molecular sieves, the compressed air dew point at atmospheric pressure is only around -20°C, with a moisture content of 1.07g/m³. The water absorption of the carbon molecular sieves is 14 times higher than that of other companies. |
| 3 | Protect the carbon molecular sieve from the contamination of trace oil and moisture, which may lead to the decrease of adsorption performance and mechanical strength, and extend the service life of the carbon molecular sieve. |
Carbon molecular sieves are easily contaminated by trace oil and moisture, leading to a decrease in adsorption performance and mechanical strength over time. Additionally, excessive moisture absorption can cause powdering and fragmentation, compromising the service life. |
| 4 | The scientific structural design avoids the direct impact of the airflow on the carbon molecular sieve, and the pulverization and breakage of the molecular sieve caused by high-speed impact. | Direct airflow impacts the carbon molecular sieves, easily causing powdering and fragmentation. The powdered carbon particles can lead to valve leakage and jamming, increasing the failure rate. |
| 5 | The unique structural design reduces the flow rate of air in the adsorption tower, so that the adsorption performance of the carbon molecular sieve can be fully utilized, which is conducive to the improvement of nitrogen purity. Nitrogen with a purity of more than 99.999% can be produced in one step. | With a higher air velocity, the adsorption performance of the carbon molecular sieves is not fully utilized, significantly affecting the improvement of nitrogen purity. It is difficult to achieve nitrogen purity above 99.999% in a single step. |
