As the core equipment of industrial gas preparation,
nitrogen generator provides high purity nitrogen for various industries around the world by separating nitrogen in the air. As a
ZAKF Screw Air Compressor manufacturer with 20 years of experience and 60,000 square meters of production base, our nitrogen generator supports CE/ASME and other global certifications and customization, with a production capacity of 300 units per month, and relying on 7 overseas warehouses to achieve 15-day speedy delivery in Southeast Asia/Middle East. The following is an analysis of the core functions of nitrogen generators and ZAKF's specialized solutions from technical principles to industry scenarios.
Nitrogen generator purifies 78% of nitrogen in the air to 95%-99.999% purity by Pressure Swing Adsorption (PSA), Membrane Separation, or Deep Cooling method, and its main functions include:
Inert gas protection: to isolate the oxygen to prevent oxidization, such as anti-corrosion of food packaging and anti-combustion of lithium battery injection;
Atmosphere replacement: to exclude flammable and explosive gases, such as inerting of chemical reactor before driving. Inerting treatment before driving;
Pressure conveying: using nitrogen pressure to convey powder materials, such as the pipeline transmission of APIs in pharmaceutical factories;
Cryogenic cooling: high-purity liquid nitrogen is used in the low-temperature process of semiconductor wafers.
