Nitrogen making machine refers to equipment that uses air as raw material and uses physical methods to separate oxygen and nitrogen to obtain nitrogen. nitrogen making machine used in industry can be divided into three types according to different classification methods, namely, cryogenic air separation method, molecular sieve air separation method and membrane air separation method.

The nitrogen making machine is a nitrogen production equipment designed and manufactured according to pressure swing adsorption technology. The nitrogen making machine uses high-quality imported carbon molecular sieve as the adsorbent, and uses the principle of pressure swing adsorption at room temperature to separate air to produce high-purity nitrogen. Usually two adsorption towers are used in parallel, and the imported PLC controls the imported pneumatic valve to automatically operate, alternately carry out pressurized adsorption and decompression regeneration, complete the nitrogen and oxygen separation, and obtain the required high-purity nitrogen. Mainly divided into the following methods:

Cryogenic nitrogen production by air separation is a traditional nitrogen production method with a history of several decades. It uses air as raw material, compressed and purified, and then uses heat exchange to liquefy the air into liquid air. Molecular sieve air separation nitrogen production uses air as raw material, carbon molecular sieve as adsorbent, and uses the principle of pressure swing adsorption to use carbon molecular sieve to selectively adsorb oxygen and nitrogen to separate nitrogen and oxygen. It is commonly known as PSA nitrogen production. Membrane air separation for nitrogen production uses air as raw material. Under certain pressure conditions, gases with different properties such as oxygen and nitrogen have different permeation rates in the membrane to separate oxygen and nitrogen.
