Yili PSA Nitrogen Generator Installed & Commissioned Within One Day — Now Serving a Renowned Heat Treatment Company

Industrial heat treatment is a critical process that determines the quality of metal parts, and nitrogen — as the core protective atmosphere gas — directly affects product quality and operating costs through its purity and supply stability. Recently, the installation and commissioning team of Yili Machinery delivered a remarkably efficient project — “installed in one day, commissioned with overtime the same evening” — successfully deploying a PSA nitrogen generator for a renowned domestic heat treatment company, officially bringing Yili's nitrogen generators into this customer's core production line.

The Customer's Pain Point: Why Heat Treatment Needs More Stable, Purer Nitrogen

This heat treatment company had long relied on purchasing bottled nitrogen or liquid nitrogen. As production capacity grew, the problems became increasingly evident:

· High supply costs: Large nitrogen consumption meant external procurement expenses kept rising year after year;

· Supply chain fluctuations: Whenever nitrogen delivery was delayed, the entire heat treatment line had to stop, directly causing financial losses;

· Unstable purity: Purity fluctuations led to oxidation, decarburization and other defects during heating, reducing the yield rate.

For heat treatment, nitrogen must not only be “sufficient” but also “stable, pure and controllable.” This is precisely why the company ultimately decided to adopt an on-site nitrogen generation solution.

Yili PSA Nitrogen Generator: Performance That Meets High Requirements

The Yili PSA (Pressure Swing Adsorption) nitrogen generator separates nitrogen from oxygen efficiently through the selective adsorption of carbon molecular sieves. Its core performance features include:

· High and stable purity: Nitrogen purity up to 99.9%–99.999%, adjustable to meet the strict oxygen-content requirements of protective atmospheres;

· Energy-saving and economical: On-site generation eliminates the procurement and transportation costs of cylinders and liquid nitrogen, significantly reducing unit gas costs with a short payback period;

· Highly automated: Equipped with an intelligent control system supporting automatic start/stop, online monitoring and fault alarms, requiring no dedicated operator;

· Safe, reliable and easy to maintain: Key components are sourced from premium brands, with compact design and simple routine maintenance for long-term stable operation.

Why Choose Yili: Not Just Equipment, But Professional Service

During the selection process, this heat treatment company compared multiple nitrogen generator manufacturers. Yili was ultimately chosen for three key reasons:

· Industry experience: Yili has long been dedicated to industrial gas equipment, serving many heat treatment and metal processing customers with demanding nitrogen quality requirements, and deeply understands the special supply needs of heat treatment processes;

· Product quality: From adsorption towers and valves to control systems, Yili nitrogen generators adhere to high standards in component selection and strict factory inspection to ensure reliability;

· Service responsiveness: Every minute a heat treatment line is idle is a cost. Yili fully understands this and consistently commits to rapid installation and rapid start-up.

Installed in one day, commissioned with overtime the same evening — this reflects both full responsibility toward the customer's production schedule and Yili Machinery's professional capability and service attitude.

Installed in One Day, Commissioned with Overtime the Same Evening

In this project, Yili's installation team planned equipment layout and pipeline connections immediately upon arrival and completed the main installation as quickly as possible. Facing a tight schedule, the team proactively chose to work overtime that evening, completing pipeline leak tests, system integration and purity testing to ensure all parameters met process requirements before formal handover.

After the equipment was put into operation, the customer's heat treatment nitrogen supply immediately became self-sufficient, supply costs dropped significantly, and product quality stability improved.
