Principle of Small Containerized Nitrogen Generator

The PSA nitrogen generator is a nitrogen production equipment designed and manufactured based on pressure swing adsorption technology. Using high-quality carbon molecular sieve as the adsorbent, the nitrogen generator employs the principle of pressure swing adsorption (PSA) at room temperature to separate nitrogen and oxygen from the air, producing high-purity nitrogen. Typically, two adsorption towers are used in parallel, with imported PLC controlling the inlet pneumatic valves for automatic operation. The process alternates between pressurized adsorption and depressurized regeneration to achieve nitrogen-oxygen separation and obtain the required high-purity nitrogen.

Equipment Features of Small Containerized Nitrogen Generator

(1) Convenient and Fast Nitrogen Production:

Advanced technology and a unique airflow distributor ensure even distribution of airflow, efficiently utilizing the carbon molecular sieve. Qualified nitrogen can be provided in about 20 minutes.

(2) Easy to Use:

The equipment features a compact structure, integrated skid-mounted design, small footprint, and no need for infrastructure investment. It requires low investment, and nitrogen production can be initiated on-site simply by connecting to a power source.

(3) More Economical Than Other Nitrogen Supply Methods:

PSA technology is a simple nitrogen production method that uses air as the raw material. Its energy consumption is limited to the electricity used by the air compressor, offering advantages such as low operating costs, low energy consumption, and high efficiency.

(4) Automated Operation Through Mechatronic Design:

Imported PLC controls fully automatic operation. Nitrogen flow, pressure, and purity are adjustable and continuously displayed, enabling unmanned operation.
