Nitrogen Purifier

At a specific temperature, residual oxygen in the feed nitrogen reacts with the carbon-supported catalyst to form carbon dioxide. This is followed by pressure swing adsorption (PSA) technology to remove carbon dioxide and moisture. After further treatment with an efficient filtration system, high-purity nitrogen with a purity exceeding 99.999% is obtained.

Application

▔▔▔

Semiconductor Manufacturing

Semiconductor manufacturing normally consumes small but ultra-high-purity nitrogen (≤50 Nm³/h at 99.999–99.9999% purity) to protect highly sensitive processes and prevent microscopic contamination

Laboratory Gas Supply

Laboratories typically require low nitrogen flow at 99.99–99.9999% purity for analytical instruments, experiments, and controlled environments

Pharmaceutical Production

Pharmaceutical manufacturing typically uses medium nitrogen flow at 99.9–99.999% purity for inerting, drying, and product protection during critical processes

FAQ

▔▔▔

Why is nitrogen purification needed?

Standard PSA systems typically produce nitrogen with 95–99% purity. For ultra-high purity nitrogen (up to 99.999%), additional purification is required. Our nitrogen purifier uses specialized adsorbents to remove residual oxygen, moisture, and other impurities, ensuring ultra-high purity for critical applications.
Can we use only nitrogen purifer to generate high purity nitrogen above 99.9999%?

No, unfortunately. The nitrogen purifier can not be used alone as a standalone unit. It is being required as the second step to purify the standard nitrogen into purified nitrogen.
Can nitrogen purification equipment operate continuously?

Yes, it is designed for continuous 24/7 operation.
How often does the adsorbent in a nitrogen purifier need replacement?

With proper maintenance, the molecular sieve typically lasts up to 5 years.
What is the typical maintenance cost for nitrogen purification equipment?

It varies based on unit size and configuration.
Why choose on-site nitrogen generation instead of liquid or bottled nitrogen?

On-site nitrogen generation offers lower investment and operating costs, requires less space, and is easier to manage and maintain compared to liquid or bottled nitrogen supply.
How energy-efficient is the system compared to liquid nitrogen supply?

On-site nitrogen generation significantly reduces energy and logistics costs compared to liquid nitrogen. Optimized PSA cycles deliver a faster ROI and lower long-term operating expenses.
How energy-efficient is the system compared to liquid nitrogen supply?

On-site nitrogen generation significantly reduces energy and logistics costs compared to liquid nitrogen. Optimized PSA cycles deliver a faster ROI and lower long-term operating expenses.
How does on-site gas equipment ensure gas purity and stability?

Each unit is rigorously factory-tested to meet purity, flowrate, and performance standards. With regular maintenance, the system provides stable and reliable nitrogen output.
Can the system be integrated with an existing nitrogen generator?

Yes. Nitrogen purifiers is a standalone unit which can be later added to the regular nitrogen generator in order to achieve higher nitrogen purity.
