Dinex DEF Dosing Modules provide precise, reliable Diesel Exhaust Fluid delivery into the exhaust aftertreatment system?ensuring optimal SCR catalyst performance and EPA compliance on Class 6-8 trucks and buses.;;The DEF dosing module meters and atomizes Diesel Exhaust Fluid into the exhaust stream upstream of the SCR catalyst. Accurate DEF dosing is directly linked to the SCR's ability to convert NOx into harmless nitrogen and water. Under-dosing results in NOx emissions exceeding EPA limits;;over-dosing causes crystallization and catalyst damage.;;Dinex DEF dosing modules are engineered to OEM specifications for direct, trouble-free replacement. Built with materials that resist the corrosive nature of DEF and tested for reliable performance across the full range of temperatures encountered in commercial truck and bus operation, our dosing modules deliver long-lasting, maintenance-free service.;;Covering EPA 10, 17, and 21 systems for all major makes and models, Dinex DEF dosing modules are part of our comprehensive mechatronics portfolio?providing a single-source solution for all DEF system component needs, from filters and pumps to sensors and complete dosing assemblies.
