For all SCR systems operated with 32.5% urea solution (AdBlue®, DEF), concentrate, sensitive to frost Ash-free additive combination to prevent malfunctions in the SCR system of diesel engines. Reduces the formation of deposits in the AdBlue® tank and AdBlue® injection system. Ensures finest atomization of the urea solution by reducing surface tension. Optimizes the return of AdBlue® to the system, thus minimizing the risk of AdBlue® crystallization. Note: For continuous use. Do not add to fuel! When adding to the AdBlue® tank, ideally add after the filling process. Shake up sediment at room temperature! Application: Add 0.25% to the AdBlue® solution (1:400) 25 ml is sufficient for 10 l AdBlue® 250 ml is sufficient for 100 l AdBlue® 2.5 l is sufficient for 1000 l AdBlue® For continuous use. Do not add to fuel! When adding to the AdBlue® tank, ideally add after the filling process. Note: Sensitive to frost. Shake up sediment at room temperature!
