Capabilities
A 100+ engineer service organization with test-equipped bases across China, a self-built drive-monitoring platform, and engineering capability from design through commissioning.
Bases beside the production lines
Global headquarters in Nanjing, Zhejiang regional headquarters in Hangzhou, seven branch companies, and service bases equipped with drive test and repair platforms for inspection, diagnosis, repair and trial runs. In 2022 DUCHENG launched a five-year plan for a 15-region service network; the newest base opened at Zhangjiagang in February 2026 — built, in the company's words, to solve concrete problems beside the production line.
A drive-monitoring platform built on ten-plus years of VFD know-how
Drive failures are long-cycle, low-frequency and highly random. The group's self-built IoT platform, operated in China, collects and stores key drive parameters in real time, analyzes condition across the whole lifecycle, and uses trend models to warn before IGBTs, power units and capacitor banks drift out of health. For Thailand and Southeast Asia projects, remote monitoring is assessed per project.
Key operating parameters collected and stored continuously, with whole-lifecycle condition visualization
Trend analysis of key indicators for early warning and fault prediction — built on industrial data and service experience
Equipment management · health diagnosis · inspection · faults · alarms · spare-parts management
From design to commissioning
Integrated capability across R&D, design, complete-set supply, installation and commissioning of AC/DC drive and automation systems — with users across ten-plus Chinese provinces and published integration work in Iran, Ethiopia and India.
