The narrow residence time distribution enables fast and efficient change-over from one specific product grade to the other. For these reasons the SMR® reactors have become a standard for polymerization reactions and heat exchange in highly viscous applications. Pilot scale SMR® equipment, as well as mono-tube bench scale reactors filled with SMXL® in-line mixers are available for client testing..

Through the division into several temperature zones operated at different temperatures, the temperature profile along the reactor can be adapted to the specific reaction kinetics. This results in a high operational flexibility and improved product quality. Moreover, the absence of moving parts involved in the process minimize the mechanical maintenance and required spare parts. Safety and environmental advantages are inherent to the design and add more reasons to opt for a cost effective solution using Sulzer Mixer Reactors.
