Product features

1. Highly cost-effective

One-time investment, long-term benefits. While there is an initial equipment purchase cost, operating costs are extremely low, far lower than the long-term cost of purchasing liquid nitrogen or bottled nitrogen from external suppliers. The payback period is typically short (1-3 years).

2. Convenient to use: Production is immediate and on-demand. There's no need to worry about transporting, renting, or managing liquid nitrogen storage tanks.

3. Flexible adjustment of purity and flow rate. By adjusting equipment parameters (such as flow rate and pressure), nitrogen with varying purities (from 95% to 99.9995% or even higher) can be produced. Flow rates can also be customized to meet specific needs, providing exceptional flexibility.

4. Safe and reliable: Eliminating the potential safety risks associated with using high-pressure cylinders and cryogenic liquid nitrogen. Nitrogen is produced on-site at low pressure, providing a high safety factor.

5. Highly automated: Utilizing a PLC control system, the system enables fully automatic operation, simple operation, and easy maintenance. 6. Environmentally Friendly

The raw material is inexhaustible air, and the production process produces no pollutants, making it a green and environmentally friendly method of nitrogen production.
