Brief introduction of the product
Pressure-variable adsorption nitrogen generator (PSA nitrogen generator for short) is a nitrogen generating equipment designed and manufactured according to pressure-variable adsorption technology. Usually two adsorption towers are connected in parallel, and the timing is strictly controlled by the fully automatic control system according to a specific programmable procedure, which alternately carries out pressurized adsorption and decompression and regeneration to complete the separation of ammonia and oxygen, and obtain the required high-purity ammonia gas. It is used for the protective gas of metal heat treatment process, the production gas of chemical industry and various types of tanks and pipelines for nitrogen filling and purification, the production gas of rubber and plastic products, the oxygen-exhausting and preserving packaging in food industry, the purification and covering gas in beverage industry, the nitrogen-exhausting and nitrogen-charging packaging and containers in pharmaceutical industry, and the protective gas of the electronic components and semiconductor manufacturing process in electronic industry.
