Product Characteristic

▔▔▔

Real-Time Data Monitoring

The PLC continuously tracks system status, alarms, and performance data, providing full visibility into operating conditions

Flexible Flow Adjustment

Nitrogen flow rate can be easily adjusted to match real-time production needs, ensuring optimal efficiency across varying operating conditions

High Purity Output

Achieves nitrogen purity up to 99.999% with a single standalone unit, meeting the most demanding industrial and process requirements

Application

▔▔▔

Food Packaging

Modified atmosphere packaging lines usually consume 50–200 Nm³/h of nitrogen at 99–99.9% purity to extend shelf life and preserve food quality

Electronics Assembly & SMT

Electronics and SMT soldering processes require moderate nitrogen volumes at 99.9–99.99% purity to reduce oxidation and improve solder joint reliability

Precision Optics & Components

Optical and precision component manufacturing consumes low-flow, high-purity nitrogen (99.999%) to prevent surface contamination during assembly and storage

FAQ

▔▔▔

Why choose a modular nitrogen generator?

Unlike traditional multi-tower nitrogen systems, the modular design uses high-strength aluminum profiles for a more compact structure and enhanced performance. Its streamlined architecture reduces installation costs and footprint, while the flexible layout enables easy deployment anywhere in your facility.
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 does the operating cost of on-site nitrogen generation compare to liquid or bottled nitrogen supply?

The operating cost of on-site nitrogen generation is significantly lower due to the elimination of transportation, rental, and storage fees.
Is on-site nitrogen generation suitable for small businesses?

Yes, it’s highly suitable. With a quick return on investment, small businesses often gain greater cost advantages using on-site nitrogen generators.
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 our production capacity be expanded in the future?

Yes. The system supports modular expansion. Additional banks can be added later to meet growing nitrogen demand without buying a new complete unit. (upto three banks)
Is remote monitoring supported?

Yes. The integrated PLC system supports remote monitoring, alarm notifications, and system status supervision, using Wi-Fi or 5G Network.
How often does the adsorbent in a nitrogen generator need replacement?

With proper maintenance, the molecular sieve typically lasts up to 5 years.
Is maintenance frequent?

No. The optimized structure, modular design, and premium components significantly reduce maintenance frequency. Detailed maintenance list and schedule can be requested at support@kstkmanufacturing.com
