China wholesale Nitrogen Making Machine - Liquid Nitrogen plant Liquid Nitrogen Gas plant, Pure Nitrogen Plant with Tanks – OuRui

Product Advantages

We construct oxygen plant for cylinder filling with best materials and components. We customize the plants as per customer requirements and local conditions. We stand out in the industrial gas market we offer the best combination of cost and efficiency our systems. Being fully automated, the plants can run unattended and can also perform remote diagnostic troubleshooting. Precision designing increases efficiency and lowers power consumption thereby saving significant proportion of bills on operational and maintenance costs. Moreover, return on investment of our onsite oxygen systems is excellent allowing the customers to break even within two years.

Application Fields

Oxygen, nitrogen, argon and other rare gas produced by air separation unit are widely used in steel, chemical

industry,refinery,glass, rubber, electronics, healthcare, food, metals, power generation and other industries.
