ZDJ nitrogen making machine is widely used in food industry, packaging, storage preservation, wine package and save and medicine, electronics, coal mining, oil and other industries.

The equipment running low cost, simple structure, cover an area of an area small, safe and reliable, convenient operation, high recovery rate, etc.

The working principle of This equipment adopts the principle of pressure swing adsorption (PSA, the use of carbon molecular sieve pressure change has the ability of separation of nitrogen in the air, using air as raw materials, the compressed air after degreasing, drying, filtration, etc

After purification treatment, into the twin towers of the adsorption component, the compressed air in the Canon of overvoltage produced after adsorption of nitrogen, and the other in desorption tower regeneration, the cycle of two towers, can constantly get cheap nitrogen purity is 98-99.9%.
