Box PSA Nitrogen Generator

We proudly introduce the GNX series of box nitrogen generators. This series features a compact design, automated operation, and long-term stable performance.

For industries reliant on high-purity nitrogen—from food packaging to electronics manufacturing—reliable on-site nitrogen supply is no longer a luxury, but a necessity for cost control and process stability.

Why the GNX Series Stands Out

1. Higher Efficiency, Lower Consumption

Thanks to an innovative bottom equalization device, the GNX series increases nitrogen production capacity by 50% while reducing air consumption by 25%.

This translates directly into lower energy bills and smaller compressed air requirements.

2. Patented Adsorption & Dust Control

■ Patented pressed‑adsorption vessel – prevents molecular sieve powdering, extending sieve life.

■ Integrated buffer tank with removable dust filter – combines storage and fine dust removal in one footprint.

3. Full Automation, Minimal Operator Attention

All models come standard with:

■ Color touchscreen HMI – intuitive control, valve status monitoring, and alarm feedback.

■ Modbus RS485 communication – real‑time purity monitoring and remote control.

■ Local + remote control – external start/stop available.

■ Smart venting – automatically vents off‑spec nitrogen until purity returns to setpoint; only合格 gas goes to your process.

■ High‑pressure standby – automatically stops nitrogen production when no gas is being used, saving compressed air and energy.

4. Precision Instrumentation

■ Binder‑grade high‑purity nitrogen analyzer (original) – real‑time purity display.

■ High‑precision pressure sensor – outlet pressure shown on touchscreen.

■ Outlet flow regulating valve + high‑accuracy flowmeter – let you adjust flow precisely to match process demand.

5. Expandable for Special Conditions

■ Optional pending‑start module – unit starts only after inlet pressure reaches setpoint, avoiding waste during low‑supply conditions.

Typical Purity & Applications (GNX cabinet series)

Where a Cabinet‑Type Nitrogen Generator Excels

■ Produce on demand – no cylinder delivery, no rental fees, no changeover downtime. Ideal for continuous or batch use.

■ Small footprint, moveable – fits workshops, labs, and small factories where space is tight.

■ Lower long‑term cost – much more economical than bottled nitrogen, especially for low to medium flow rates.

■ PLC one‑touch start, unattended operation – reduces labor cost and human error.

Built for Professional Users Who Care About Uptime

The GNX series is not a “nice‑to‑have” accessory. It is a process stability tool.

Whether you are running an SMT line, a laser cutter, or a food packaging machine, a PSA nitrogen making machine from the GNX series gives you purity you can trust, flow you can control, and reliability you can measure.

Want to know more?

If your application demands consistent nitrogen purity without the logistics of cylinders or the risk of liquid nitrogen supply interruptions, the GNX series is worth a closer look.
