Shanghai Donjun Automation Equipment Co Ltd

Shanghai Donjun Automation Equipment Co., Ltd. has been in the game since 1996, working mainly with marine automation systems. They’re based in Pudong, Shanghai, and they’ve built their business around producing and supporting control equipment that helps ships run safely and efficiently. Their work covers a lot of ground - valve remote control systems, level gauging, BNWAS, and water ingress detection, just to name a few. All of these are critical systems on modern vessels, and Donjun’s gear gets installed on everything from cargo ships to tankers. They build their own products in-house and offer custom solutions when the job calls for it. What makes them stand out a bit is their network. Donjun works with major classification societies like ABS, LR, RINA, BV, and CCS, which gives them the ability to meet strict international standards. They’ve also worked alongside familiar global names like Siemens, ABB, and Bosch Rexroth, supplying electrical and automation components for integration jobs or full system installs. They’re not just a factory operation either - they’ve got an active technical service team and provide onboard support, repairs, and calibration work when needed. A good chunk of their business is also tied to refits and upgrades, where they help shipowners modernize older systems. With over 25 years in the industry, a solid factory base, and experience across both Asia and global shipbuilding hubs, Shanghai Donjun keeps its focus on what it does best - smart automation built to last.
