Abstract

The static mixer for viscous media comprises a tube and at least one mixing element arranged in the tube. The tube defines a main flow direction of the fluid to be mixed. The mixing element is formed as a monolithic structure with bars crossing one another and the bars each have an essentially rectangular cross section with a large and a small side. Crossing points of the bars are reinforced by local thickened portions. As a result of these thickened portions a common boundary surface between the bars which lies parallel to the main flow direction is at least about twice as large as the square area formed by the small side.
