Founded in 2009 and headquartered in Hangzhou—China's hub for industrial gases—Domex-E is Siemens Energy®'s Greater China Skid Integrator for integrally geared air separation compressors and Air Liquide® ALT's global skid integration center for expanders. We do more than deliver once—we partner with customers across the full turbomachinery lifecycle.
We aim to be a long-term, trusted partner in turbomachinery systems. Across the full equipment lifecycle, we integrate selection, integration, skid packaging, O&M, spare parts, and retrofit capabilities so customers receive stable, professional, ongoing support at every stage. This approach defines how we choose partnerships, build our teams, and measure our value.
Through reliable engineering and responsive service, we keep customer equipment running efficiently.
Moving from reactive response to proactive foresight—offering better solutions before risks materialize.
Behind our technical systems are engineers committed to detail, accountability, and results.
We focus not only on delivery, but on our customers' long-term, sustainable operational performance.
From our Hangzhou headquarters, we have built a service network across eastern, southern, and western China, supported by factory-based skid packaging and spare parts logistics. Our reach extends from China to Asia and Europe, delivering stable, professional support to a growing customer base.
We are committed to a more efficient industrial future—helping customers reduce energy consumption and emissions through turbomachinery optimization, energy efficiency retrofits, and full-lifecycle services while keeping critical equipment running reliably.
Energy Efficiency Retrofit
Industrial progress depends on developing talent across generations. Domex-E established a university textbook fund to support professional curriculum development—bringing knowledge in turbomachinery, fluid machinery, and automatic control back into the classroom to support the next generation of engineers.Read the textbook fund story。
A nationally recognized textbook edited by Zheng Jinyang and Sang Zhifu, published by Chemical Industry Press. Through our textbook fund and university partnerships, Domex-E brings systematic knowledge of process equipment and pressure vessels back to the classroom, helping the next generation of engineers build a solid foundation.
