Proventia SuperTornado - Urea Mixing Technology - Brochure

SCR technology uses ammonia in the form of a urea-water solution (DEF/ AdBlue) as a reducing agent for catalytic reactions. Particularly if an airless injector is used, the urea solution has a tendency to form deposits (urea crystallization) in the process of evaporation and decomposition into ammonia. To prevent the build-up of deposits and to obtain good uniformity in the catalyst cell, an efficient mixer is needed. Particularly in limited-space applications  and in real driving cycles that include slow driving with low loads, the high NOx reduction targets of today´s regulations cannot be reached without efficient urea mixing. The key to solving mixing problems is to have an effective urea mixer, such as the Proventia SuperTornado.
