Microchannel Devices (µCD) produces semi-finished and finished products featuring micro.channel patterns, aimed at energy transition processes and green economy. The products of µCD cover the entire chain of production, distribution and use of hydrogen, LNG, use and conversion of CO2, both for power generation applications and for chemical and biological reactors. A fully verticalized manufacturing process allows MCD to manufacture products caractherized by any pattern of micro-channels for fluid management like: bipolar plates, PCHE (printed circuit heat exchangers) and chemical reactors. The processes fully mastered by MCD are the deep photo-chemical etching on metal plates with capability of very large formats and the solid-state welding process known as Diffusion Bonding.
