CLEARNOX® is used in the exhaust gas aftertreatment process in vehicles equipped with a Selective Catalytic Reduction (SCR) system (i.e. from Euro IV vehicles). This urea-based solution helps reduce the nitrogen oxide (NOx), emissions produced by diesel engines. CLEARNOX® is a preventive solution that keeps crystals from forming in the SCR system. Using it continuously keeps SCR systems working efficiently. This product has a CDS coupler that allows to pump the fluid from an IBC.
