Zhejiang Sanhua Intelligent Controls

The story of Zhejiang Sanhua Intelligent Controls begins not in a boardroom, but in a small agricultural machinery repair shop founded in 1967. The pivotal moment came in 1984 when founder Zhang Daocai took the helm, renaming the struggling factory to focus on refrigeration components. This marked the true start of Sanhua. Initially, the company focused on developing key components like solenoid valves and reversing valves for the then-emerging HVAC and refrigeration markets in China. This focus on core technology and manufacturing excellence allowed the company to grow steadily. A significant step in its journey was the establishment of a dedicated R&D department in 2004, fostering collaboration with universities. The following year, in 2005, Zhejiang Sanhua Intelligent Controls achieved a major milestone with its Initial Public Offering on the Shenzhen Stock Exchange. This event provided the capital for significant expansion. The company grew through strategic acquisitions, which broadened its technological capabilities and global reach. Over the years, Sanhua expanded its product lines to include components for automotive thermal management, supplying major international brands. In June 2025, the company completed a dual listing, launching on the Hong Kong Stock Exchange to further fuel its global strategy.
