Core Technology: Box-integrated PSA Precision Separation System
The Pressure Swing Adsorption (PSA) nitrogen generator is an automated device that uses carbon molecular sieve as adsorbent. It adsorbs oxygen from the air based on pressurization adsorption and depressurization desorption to separate nitrogen. All functional modules are highly integrated into a closed box. When compressed air is connected, it enters the built-in air pretreatment system (precision filters and refrigerated dryers) to remove dust, oil and moisture, ensuring the air meets "oil-free, water-free and dust-free" standards.
The device is equipped with two adsorption towers inside the box, automatically controlled by the PLC system to alternately perform the adsorption-desorption cycle, realizing continuous nitrogen production. The closed box structure reduces interference from external dust and moisture, keeps the equipment neat, and complies with 5S workshop management standards.
Raw Material Advantage: Zero Restriction
- No procurement cost: No need to purchase chemical raw materials, completely avoiding expenditure on liquid nitrogen and bottled nitrogen.
- No storage risk: No dangerous storage containers (cryogenic tanks, high-pressure cylinders), avoiding safety hazards such as low-temperature frostbite and gas cylinder explosion.
- No supply restriction: Air is an unlimited raw material, unaffected by logistics or supplier capacity, ensuring continuous production even in extreme weather.

Working Principle
The Box-type Nitrogen Generator operates on the Pressure Swing Adsorption (PSA) principle. Using carbon molecular sieve (CMS) as the adsorbent, the system separates nitrogen from compressed air by exploiting the different adsorption rates of oxygen and nitrogen molecules.
Oxygen molecules diffuse faster and are adsorbed into the micropores of the CMS under pressure, while nitrogen molecules pass through and are collected as product gas. When the adsorption tower reaches saturation, the system depressurizes to release the adsorbed oxygen, regenerating the molecular sieve for the next cycle.
Dual-Tower Alternating Cycle
The equipment has two adsorption towers inside the box, controlled by PLC to alternately perform adsorption and regeneration. This ensures continuous, stable nitrogen supply with purity adjustable from 90% to 99.999%.
