Senior🎓
Top SchoolStefan Rohlfing is an international sales executive with 15 years of experience specializing in Chinese drilling equipment, oil waste recovery systems, and eyewear manufacturing, who has lived and worked in China for over 20 years. He currently represents Zoom Petro’s indirect thermal desorption solutions—deployed by major players like Sinopec—for turning oily sludge and drilling mud into sellable hydrocarbons in harsh, remote environments. Previously as COO of Sovonex he oversaw turnkey land and truck-mounted rigs, process equipment and top-drive maintenance, giving him deep operational and supply-chain knowledge of China’s oilfield manufacturing base. He has hands-on international project experience coordinating tank cleaning and sludge-recovery deployments across Southeast Asia and India. Fluent in navigating Chinese manufacturing ecosystems and international clients, Stefan combines technical product understanding with practical field deployment know-how. An understated strength is his ability to translate complex treatment advantages (low water use, no proprietary chemicals, preserved hydrocarbon quality) into commercially viable projects for arid and remote sites.
