N2GEN: Mission-Critical Nitrogen™ Generators for Heat-Treating Processes

For years, the heat treating industry has depended on the inert properties of nitrogen to push oxygen out of high-temperature environments, often requiring high flowrates and purities in a short amount of time. South-Tek Systems’ mission-critical nitrogen™ generators are engineered to reliably deliver the exact purity and flowrate your Heat - Treating process requires.

Mission-Critical Nitrogen™

Nitrogen generators offer the most benefit when a continuous flow atmosphere of either pure N2 or N2 as a component is needed. Typical combinations include N2/ H2, N2/CH4, or just N2 for cover gas in N2 tempering, stress relieving, normalizing, annealing, hardening, or CAAB (continuous atmosphere aluminum brazing).

Nitrogen generation is also suitable for continuous flow applications where N2/ methanol atmospheres are needed, such as carburizing and neutral hardening. Additional examples of application use include chamber purging before FNC (means Ferritic nitrocarburizing), nitriding, as well as feeding N2 flow as required by vacuum degreasers.

Main benefits of PSA Technology

South Tek’s industrial N2GEN system uses dual-bed, PSA technology. The PSA (Pressure Swing Adsorption) filtration delivers 99.999% pure nitrogen while the dual- bed design allows for maximum efficiency and minimal maintenance. Combined, the dual-bed design and PSA technology are a powerful solution that provides 18-24 year system life dependent on maintenance.

In addition to hassle-free, in-house mission-critical nitrogen™ generation, clients benefit from significant cost savings and quick payback with a typical return on investment of around one year. South-Tek offers rental and purchase options – all of which provide savings.

Generating nitrogen with South Tek’s N2GEN could:

Provide 50-90% savings when compared to liquid bulk

Bring fast payback with an average ROI of 12-14 months

Make you independent of deliveries and contracts

Make it easy to monitor your generator with Smart-Trak – Touchscreen control display*

Result in 18-24 year system-life, dependent on maintenance

* remote monitoring possible with mobile devices

Cost Comparison

Traditionally, buying bulk liquid nitrogen has been the go-to solution for the Heat- Treating industry. With modern nitrogen generators dialed-in to meet the specific requirements of the heat treating industry, companies are recognizing the numerous benefits, including reducing operational expenses, and are making the switch.

Nitrogen Generator Working Principle

South-Tek’s nitrogen generation technology safely separates the readily available nitrogen from the air we breathe using Carbon Molecular Sieve (CMS). Under pressure, molecules more active than nitrogen are adsorbed into filtration media, allowing the nitrogen molecules to pass through into a storage tank for later process use. Our generators create the highest quality nitrogen (filtered beyond the air we breathe), ready for immediate use by any application.
