Thread Content
Ten years of rapid development in chemical processing equipment – praise for China’s prosperity and strength. This is just a starting point; more participation from everyone will make things even more lively. HaiChuan becomes even better with your involvement; we welcome everyone to join in the forum discussions. Everyone should pay attention to safety and know how to handle emergencies. ********************************************* On June 17, 2023, FengDian JinKaiWei (Suzhou) Compressor Co., Ltd. released China’s first 250MPa ultra-high pressure diaphragm hydrogen compressor, marking a breakthrough as the country manages to overcome technical constraints in this critical field and achieve domestic substitution for such high-pressure hydrogen equipment. In recent years, with the continuous advancement of technical processes in downstream industries and the expanding range of applications for diaphragm compressors, customers have placed higher demands on the volumetric flow rate and discharge pressure of such compressors. Therefore, diaphragm compressors with large flow rates and high discharge pressures represent an important development direction for diaphragm compressor manufacturers today and in the future. Fengdian Jinkaiwei offers more than 30 product series, including piston compressors and diaphragm compressors, which are used in various sectors such as hydrogen energy, photovoltaics and semiconductors (polysilicon, silicone), fluorine chemicals, nuclear power, military industry, and the petrochemical industry. In the niche market of process gas compressors in which the company has been active for a long time, it serves over 3,000 industrial customers. Its products cover the entire hydrogen industry chain, including compressors for hydrogen production, filling, and hydrogen refueling stations, and it can provide comprehensive solutions for gas compression equipment. At the press conference, General Manager Liu Jie said that the 250MPa ultra-high pressure diaphragm hydrogen compressor introduced this time successfully addressed issues such as the complexity of the design theory for ultra-high pressure diaphragm compressors, ultra-high pressure sealing, and the replacement of key components at the inlet stage; it also enabled verification of the material’s resistance to hydrogen embrittlement. Most importantly, a fully domestic supply chain for ultra-high pressure diaphragm compressors has been established, which will lay the technical and industrial foundation for the large-scale use of 90MPa and 45MPa diaphragm compressors in China’s hydrogen energy market in the future. Process compressors are one of the key devices in areas such as the production and filling of hydrogen and specialty gases, the fluorine chemistry industry used in the upstream stages of lithium batteries, the silicon chemistry industry in the upstream sectors of the photovoltaic and semiconductor industries, hydrogen refueling stations for hydrogen fuel cell vehicles, and the construction of nuclear power plants. The development of these industries continues to drive growth in the market for process compressors.
Fengdian Jinkaiwei focuses on the research and development of process gas compressors; its products cover the entire hydrogen energy industry chain. In 2022, the company generated revenue of 187 million yuan, a year-on-year increase of 141.55%. In terms of facility development, production bases are continuously upgraded. The annual report shows that by the end of 2022, a new factory for Fengdian Jinkaiwei’s hydrogen compressors was completed and put into operation in Changshu, with an planned production capacity of 800–1 billion units; this new capacity is yet to be fully utilized. In terms of investment in research and development, the company continues to increase spending on R&D and market promotion as well as on optimizing its human resources. In 2022, it invested 17.1804 million yuan in R&D, accounting for 5.06% of its total expenditures. Fengdian Jinkaiwei developed China’s first 250Mpa ultra-high pressure hydrogen compressor; the prototype of this compressor was completed and tested, and it received recognition from customers, leading to project orders. The “250MPa ultra-high pressure diaphragm hydrogen compressor” and the “90MPa diaphragm hydrogen compressor for hydrogen refueling stations” have passed the product evaluation conducted by the China General Machinery Industry Association, laying a solid foundation for seizing opportunities in emerging markets.
