Kaifeng Air Separation Group Co.

What Kaifeng Air Separation Group Co. does

Kaifeng Air Separation Group Co. is a Chinese state-owned industrial equipment manufacturer founded in 1958 and headquartered in Kaifeng, Henan Province, operating as a subsidiary of Henan Energy Chemical Industry Group. The company designs, manufactures, and supplies large and medium-sized cryogenic air separation units (ASUs) with oxygen capacity ranging from 1,500 to 100,000+ Nm³/h, alongside gas liquefaction equipment, pressure vessels, wound heat exchangers, aluminum plate-fin heat exchangers, centrifugal and reciprocating compressors, turboexpanders, and specialty valves used in metallurgy, petrochemical, coal chemical, LNG, and energy industries.

The company's technology stack centers on low-temperature cryogenic distillation, including proprietary structured packing columns, internal compression processes, full-refinement hydrogen-free argon production, and the domestic manufacturing capability for FLNG-grade wound heat exchangers and ultra-high temperature gas-cooled reactor intermediate heat exchangers. Kaifeng holds ASME U-stamp pressure vessel certification, national pressure vessel and pipeline design licenses, and integrates DCS/PLC automation systems from both international (Honeywell, ABB, Yokogawa, Emerson, Siemens) and domestic (Supcon, Hollysys) vendors. The group operates five wholly-owned business units: air separation equipment manufacturing, chemical equipment manufacturing, installation engineering, environmental protection engineering, and a vocational training school, with the new 1,167-acre industrial park expansion targeting 23 large ASUs plus supporting equipment annually at full capacity.

Revenue is generated primarily through project-based one-time equipment sales to enterprise customers (steel mills, petrochemical complexes, coal chemical plants, energy companies), supplemented by EPC contractor channel partnerships, installation and lifecycle maintenance services, environmental engineering contracts, and vocational training fees. Go-to-market relies on direct enterprise field sales with competitive bidding for major projects, particularly through long-term relationships with EPC contractors such as Shaanxi Guigu Power (Shaangu), Sinosteel Equipment, and Zhongye Jingcheng. The company has exported equipment to eight or more countries across Southeast Asia, the Middle East, South Asia, and Europe, with cumulative deliveries exceeding 1,000 ASU units.
