Microchannel Devices (µCD) produces micro-channel devices aimed at energy transition processes and circular economy. The products of µCD concern 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. Starting from chemical milling technologies aimed at producing photoengraved plates, integrated with 4.0 assembly technologies and innovative welding processes such as Diffusion Bonding of large dimensions, µCD designs and manufactures micro-devices and components channelled to the new frontiers of energy production (H2, Nuclear, Solar thermal), without overlooking the traditional markets (Oil&gas) providing components and devices mainly for LNG, the most «clean» hydrocarbon, essential link between the coal economy and the future green economy.
