We have been manufacturing various compact Heat Exchanger, Reactor and peripheral equipments with the collaboration of several government-supported research institutes and enterprises based on micro-fabrication technology, diffusion bonding and brazing technology. We developed Primary Surface Heat Exchanger (PSHE) lately based on the technology and experience to manufacture micro-channel heat exchanger. PSHE has high effectiveness, so it can apply to Micro Gas Turbine, Solid Oxide Fuel Cell, Heat Recovery System, Plant and other power generation system. And PSHE is compact and light, so it can apply to portable generation system and flight. We built Fin forming system uniquely that can work high stiffness material into various fine ribbing shape and LASER welding system, and we have competitive productive capacity.
