ZIQI provides a complete on-site nitrogen generation solution. Using advanced Pressure Swing Adsorption (PSA) technology and high-quality Carbon Molecular Sieves, our systems deliver continuous, high-purity nitrogen (up to 99.9995%) for food packaging, laser cutting, electronics, and chemical industries.
Rugged design built for harsh environments.
Continuous 24/7 operation capability.
Will not stop operation due to minor air supply interruptions.
Standby mode activates automatically when N2 is not needed.
Cycle time modulation algorithm reduces air consumption during low demand.
High-density filling ensures maximum adsorption efficiency.
Compact spring-loaded design prevents sieve powdering.
Protected by dedicated pressure sensors.
No special installation or complex commissioning required.
Simple connection to dry compressed air supply.
Fully automatic oxygen sensors included for monitoring.
Remote start/stop functionality.
Supports Modbus, Profibus Fieldbus, and Ethernet.
SMARTLINK intelligent monitoring system.
Automatically adjusts to required pressure and purity.
Convenient purity adjustment interface.
Safety blow-off for unqualified nitrogen.
The system uses two adsorption towers filled with Carbon Molecular Sieve (CMS). Compressed air enters the bottom of the tower; oxygen is adsorbed by the CMS while nitrogen passes through. Ideally suited for applications requiring 97% to 99.9995% purity.
