About DUCHENG Industrial

Multi-brand VFD lifecycle service for industrial customers — commissioning, preventive maintenance, repair and reconditioning, delivered in Thailand and Southeast Asia on the technical foundation of Zhejiang Ducheng Industrial Co., Ltd.

The company

Professionals doing professional work

DUCHENG operates with a dual-headquarters structure: the global headquarters is in Nanjing, while Zhejiang Ducheng Industrial Co., Ltd. has its Zhejiang regional headquarters in Hangzhou. The group has seven branch companies, multiple offices and a technical service team of more than one hundred engineers. From the coastal industrial belt, its service network has grown to cover most of China — and, through Ducheng Industrial (Thailand) Limited, Southeast Asia.

The business runs on one idea, set down in 2013: industrial plants should not have to run their own drive-maintenance departments. DUCHENG contracts the whole discipline — repair and diagnosis, preventive maintenance under contract, deep on-site reconditioning and field commissioning. Within the group in China this extends to a self-built digital O&M platform; for Thailand and Southeast Asia projects, remote monitoring is assessed per project.

DUCHENG Industrial — the group's international service brand — focuses on lifecycle services for variable-frequency drives and drive systems. Building on technical experience accumulated in China and a growing service presence in Thailand, the team supports industrial customers in keeping critical drive assets available through their operating life.
