What are the core advantages of Deere air separation in the selection of large and medium-sized air separation projects?

In terms of technology, different from most manufacturers that only guarantee the output of oxygen and nitrogen, Deere realizes the full extraction of oxygen, nitrogen, argon, helium, neon, krypton and xenon, and the output and purity of various products meet or exceed the contract indicators, so as to fully tap the value of Air Resources. In terms of delivery, the integrated mode reduces the connection problems caused by multi-party subcontracting, shortens the construction cycle, helps customers put into production quickly, and shortens the return on investment cycle. The system energy consumption is stable and meets the contract design standard, and the problem of "paper energy saving, actual high consumption" is eliminated. Intelligence is a highlight.
