Based on our integrated scale-up concept, we guarantee a fast scale-up within comparable channel geometries, whereby only a minimal cross-sectional enlargement of the channels takes place. In doing so, we retain the advantages of microreaction technology, such as high mixing quality, excellent heat transfer and targeted process control. In this way the results achieved on a laboratory scale can be quickly and easily transferred into the design of the production reactor. The required throughput is achieved, for example, by a parallel connection of channels to a channel bundle within a reactor.
