DEF Anti Crystal Additive SKU: 21801 100 ml. Ash-free combination of additives for the prevention ...DEF Anti Crystal Additive SKU: 21801 100 ml. Ash-free combination of additives for the prevention of malfunctions in the SCR system of diesel engines. Reduces the formation of deposits in the AdBlue tank and AdBlue injection system. Improves the operability at low temperatures and guarantees extremely fine atomization of the urea solution by lowering the surface tension. Optimizes the return flow of the AdBlue into the system, thereby minimizing the risk of AdBlue crystallization. For all SCR systems that are operated with 32.5 % urea solution (AdBlue, DEF). Application: Add 1 % to the AdBlue solution. 100 ml is sufficient for 12-15 l of AdBlue. For long-term application. Do not add to fuel! When adding to the AdBlue tank, should ideally be added after the filling process.
This guide provides essential information for users of Liqui Moly's AdBlue Exhaust Crystal Preventer (21801). It is designed for diesel engine owners who want to prevent malfunctions in their Selective Catalytic Reduction (SCR) systems. By using this additive, you can reduce deposit formation and improve system performance, but remember to only add it to the AdBlue solution, not directly to the fuel.
