What is the lead time for a refurbished ASU compared to a new order?

New ASU manufacturing often takes 12-18 months. Our well-preserved 2017 Kaifeng ASU can be dismantled, refurbished, and ready for shipment significantly faster, allowing your plant to start production within months

Can you guarantee the purity of the Liquid Oxygen and Nitrogen?

A: Absolutely. This KDON unit is designed for 99.6%LOX and high-purity LIN (O_2 ≤ 5ppm). We provide full performance monitoring data as proof of quality

How do you ensure the safety and success of relocating such a large-scale ASU?

We offer a comprehensive “Dismantling-to-Commissioning” service。 This includes precision labeling of all piping and instrumentation, professional export-grade packing for international transit, and on-site engineering supervision during re-installation at your facility . Our goal is to ensure the plant reaches its designed operational status efficiently at its new location。
