Proventia - SCR and Urea-Mixing Services

Improved SCR performance is to be achieved with effective urea mixing. SCR technology uses ammonia in the form of a urea-water solution (DEF/AdBlue®) as a reducing agent for catalytic reactions. Especially when an airless injector is used, the urea solution has a tendency to form deposits (urea crystallisation) during evaporation and decomposition into ammonia. An efficient mixer is required to prevent the build-up of deposits and to obtain good uniformity in the catalyst cell. Especially 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 achieved without efficient urea mixing. The key to solving mixing problems is to have an effective urea mixer such as the Proventia SuperTornado.
