Following the Jinhong Gas (Zibo) and Shaanxi Xinghua projects, Hangzhou Domex-E Gas Equipment Engineering Co., Ltd. ("Domex-E") has once again shown its strength, winning the order for the compressor trains and related services for the 2 × 120,000 Nm³/h air separation units supporting Xinjiang Dongming Plastics' 800,000 t/a coal-to-olefins project. The project is the largest order for high-end electric-driven compressor trains in China to date and another success from the company's long-term work in the Xinjiang market. It marks another key step in its strategic presence in large air separation in Xinjiang and across China. With a "hat-trick" of contract wins, Domex-E continues to demonstrate its hard strength in high-end equipment, injecting strong momentum into its high-quality development.
The Xinjiang Dongming Plastics coal-to-olefins project is a flagship project for implementing the "dual carbon" strategy and upgrading the local energy industry. Its air separation units have demanding requirements on system scale, energy efficiency and long-term stability, attracting top suppliers from China and abroad. Relying on Siemens Energy's core compression technology, Domex-E won with a "hard track record" and "extreme service". Trains of the same class have run stably in Uzbekistan for several years, attesting to the outstanding reliability of its products. Even more striking, when an impeller of an 80,000-class air separation unit in Xinjiang was suddenly severely damaged, Domex-E's service team worked around the clock and set an industry record by completing the core repair and restarting in 19 days, fully demonstrating its strong emergency support and technical service capabilities. It was this "visible strength" that led the customer to cast its vote of confidence for Domex-E.
This cooperation once again validates the systematic, comprehensive capabilities Domex-E has built over many years: customized technical solutions for special operating conditions, integrated assurance covering the whole process from design and manufacturing to commissioning and O&M, a rapid-response mechanism centred on the only spare-parts warehouse for Siemens Energy compressors, and a digital O&M platform based on AI large models and an online analysis system that enables remote diagnosis, predictive maintenance and lifecycle health management. This assurance system, deeply integrating "hard equipment" and "soft service", provides solid support for customers' trains to run stably and efficiently over the long term and avoid unplanned shutdowns, truly reflecting Domex-E's service philosophy of maximizing customer value. This is not only the successful delivery of key equipment but another strong demonstration of how Domex-E creates system value for customers, with high-end equipment at the core, in-depth service as support and ongoing collaboration as the bond.
The journey is long and every step counts. With reverence for technology, sincerity toward customers and responsibility to the times, Domex-E will keep working in industrial gas equipment and, together with its partners, build industry milestones with high-quality projects and contribute to the high-quality development of Chinese industry.
