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.

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 with an 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 of 50-90% on average and quick payback with a typical ROI of around one year. South-Tek offers rental, lease and purchase options – all of which provide savings.

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, nitriding, as well as feeding N2 flow as required by vacuum degreasers.

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.
