The dynamic cascade reactor (DCR) is equipped with an axial stirrer that actively mixes 12 CSTR cascades. It is particularly suitable for multiphase systems (gas, liquid or solid) and can therefore be used for dispersion tasks and catalytic processes. The DCR is mainly used where the limits of the static mixer have been reached, i.e. with reaction media containing solids. The scale-up from laboratory scale to production scale (100 L) has already been realized.
