Started as an oxygen-making equipment manufacturer in 1979, Kaifeng HUANGHE Air Separation Group developed into a group company in 2003, and is now engaging in self-design and manufacture of complete air separation plants, with large and medium scale ASP R & D, industrial gas marketing and new energy plant development as its main business and service covers gas sales, installation and commissioning, technical consultation, parts supply as well as after-sale service. Main products: air separation plants, air compressors and new energy plants. Until now, we have supplied more than 300 ASPs (1 500m3/h ~ 3 5000m3/h) to metallurgical, petrochemical, coal chemical, chemical, chemical fertilizer, construction material industries and exported to Nigeria, Turkey, Uzbekistan, etc. Quality and performance of air compressor we designed achieve domestic first-class level. New energy plants are opening new growth market for the enterprise. The largest on-stream ASP of Kaifeng HUANGHE Air Separation Group is 35 000m3/h model. Typical plants are: 32 000m3/h series which are of high technology; 28 000m3/h series with internal compression process which have the highest localization rate of parts and components; 20 000m3/h series which are the concentration of patent technologies; 12 000m3/h series which have the best domestic argon recovery rate (84%); 10 000m3/h series which performance are excellent, etc. 12 000m3/h series full rectification argon-making plants manufactured by Kaifeng HUANGHE Air Separation Group won the certificate of Hi-Tech Products of Henan province. Technical reserve and production capacity are up to 55000 m3/h. Centrifugal compressors and reciprocating compressors designed and manufactured by Kaifeng HUANGHE Air Separation Group are main complete unit of large and medium ASPs, featuring stable function, compact structure, reasonable configuration, high isothermal efficiency, wide working-condition range, slight vibration, low noise, convenient maintenance and long-term, safe and continuous running. Performance index of our compressors are proved to be at the industry-leading level by long-term running. Depending on its own strength, Kaifeng HUANGHE Air Separation Group has been vigorously developing new energy market and already has a patent technology of [Getting Biogenic Natural Gas (BNG) from Biogas]. Product BNG could reach national standard of compressed natural gas as vehicle fuel (GB18047-2000) and be used by cars and other high-end customers. 20 000m3/d and 100 000m3/d biogas purification plants has been completed and put into operation. Design and manufacture strength: Certificates we have: ISO9001-2008 quality management system CE certificate Design and manufacture license of A2 pressure vessel (the highest level of China) Design license of GC pressure pipeline Installation reformation and maintenance license of GC2 pressure pipeline Kaifeng HUANGHE Air Separation Group has already got 23 patent technologies, and the company was elected as the first batch of High-Tech enterprise of Henan province in 2011. We now have more than a dozen old famous experts and a group of professional engineers. Most of them have rich experience over decades and win high reputations in the ASP industry. We have our own design institute, including process engineering department, engineering department, equipment R&D department, compressor machine R&D department, heat exchanger R&D department and new energy R&D department. Our manufacturing shop covers 28000 square meters, including 266 machining equipments and testing equipments. Maximum lifting capacity of heavy-duty equipments workshop is up to 100mt. And we own a group of skillful experienced technicians and well-trained workers. All of the above form our powerful manufacturing capacity. Advantages: Technology - HUANGHE already has got 23 national patent technologies. The application of first-class argon recovery technology and unique distillation column manufacturing process makes ASPs more stable in operation, high efficiency and energy saving. Quality - HUANGHE puts quality in the first place in any case. Successful rate of commissioning of more than 300 ASPs designed and manufactured by us is 100%. Argon recovery - Argon recovery plants designed and manufactured by HUANGHE 100% reach the design performance. Argon recovery rate is the highest in domestic ASP industry. Energy saving - New technology of energy saving process got national patent and has been used to improve performance of ASPs. Unit energy consumption of ASP is 3~5% less than industry averages. Nitrogen recovery rate of high-purity nitrogen plants is up to 88%; nitrogen purity is no more than 0.12ppm oxygen and 0.15ppm argon, which is also record-breaking in domestic ASP industry. Professional - HUANGHE specializes in manufacturing ASPs in a certain range of 1000~40000m3/h, and always aims to be the best supplier in ASP industry.
