Our cabinet PSA nitrogen generator can efficiently separate nitrogen with high purity. It not only occupies small space, but also protected by a metal case, preventing damage during operation. It is suitable for low-volume nitrogen generation, such as food preservation in small food processing manufacturers, nitrogen protection in scientific laboratories, etc. Our cabinet PSA nitrogen generators are designed for meeting different requirements across various industries, detailed specification and size can be customized upon customers’ request.

• Nitrogen capacity: 3-10Nm³/h
• Nitrogen purity: 95%-99.9%

• Separated nitrogen is specially processed to be free of impurities and odor.
• The processed air source will be extremely dry, and closed to anhydrous, low-oxygen state.

PSA nitrogen generation is a technology to separate nitrogen from air by the adsorption ability of carbon molecular sieve under pressure by air compressor. After the air is compressed and purified (removing the oil, water and dust, etc.) before transferring into the absorption tower filled with carbon molecular sieves (CMS), the oxygen molecule will be adsorbed by carbon molecular sieve, while nitrogen molecules are too large so that they will be remained in the air. Those nitrogen molecules will pass through the tower into the nitrogen buffer tank, while oxygen molecules remain in the CMS. The adsorption process is performed at certain pressure, after that the atmospheric pressure will be resumed, and the adsorbed oxygen molecules will be escaped from CMS, pass the bottom of the tower through the exhaust silencing muffler into the air, and the CMS is available to be reused. Usually PSA nitrogen generator adopts double adsorption towers in parallel, they will be used alternatively for the adsorption and collection of the nitrogen under different pressure, continuously supporting the separation of oxygen and nitrogen. The above process will be automatically controlled by PLC system.

• Used before pressing, blowing and capping for packages of beer, wine, fruit wine, edible oil to prevent oxidation, spoilage and discoloration of non-carbonated beverages and cooking oils by removing oxygen.
• Used for puffed and fried food to prevent the change of flavor caused by moisture, and improve the package safety to prevent it from being damaged due to extrusion during transportation.
• Used for pastry and baked food to extend the freshness for 3-5 months, and prevent food from being damaged due to extrusion during transportation.
• A small amount of nitrogen in milk powder and soybean milk powder will help prevent or reduce the caking phenomenon caused by long-time extruded storage.
• 95% purity of nitrogen in cereals, nuts, fruits, and vegetables will help prevent harm of pest, 5% of the oxygen can help reduce the respiration rate of fruits, ensuring the freshness preservation effect.
