Aerospace methodology, applied to industrial heat exchange.
Shanghai Dongrun Heat-Exchanger Co., Ltd., founded in 2001, is a professional provider of heat exchange solutions. With an in-house testing platform, a 50+ engineer R&D team led by professor-level senior engineers, and a three-layer validation process, we deliver custom-engineered heat exchangers to Tier-1 OEMs and EPC contractors worldwide.
Corporate vision
Become a world-class leader in heat exchange solutions.
Founder
Mao Wenzhuo, professor-level senior engineer, founded Dongrun in 2001.
Before founding the company, he spent 19 years at China's AVIC 614 Aero Engine Research Institute — serving as designer, design group leader, and research division director. That aerospace background is the methodological foundation Dongrun brings to industrial heat exchange: the same rigor that applies to jet-engine cooling applies, in our work, to motor coolers, wind tunnel heat exchangers, and gas turbine inlet air cooling systems.
He chairs the company and leads the technical roadmap. The 50+ engineer R&D team he built — and the in-house testing platform he invested in — are the reasons custom designs ship with confidence.
