DINEX Selective Catalytic Reduction Assembly for Cummins Engines, 13.62" Diameter x 41.65" Length is an emissions control module engineered to reduce nitrogen oxide (NOx) in diesel exhaust streams through selective catalytic reduction using a urea-based reductant. Designed to meet EPA10 emissions norms, this SCR assembly provides fleets a direct technical solution for NOx control on Cummins-equipped vehicles. The unit ships service-ready with required clamps and gaskets to streamline installation and limit vehicle downtime during replacement events. Built around proven catalyst formulations and optimized coating technology, the assembly maintains conversion efficiency over extended service intervals to help preserve engine performance while meeting regulatory targets. Measurable operational benefits for fleet managers include reduced emissions-related roadside failures, predictable maintenance intervals driven by validated durability, and potential avoidance of regulatory nonconformity events. Physical attributes relevant to planning and installation are documented: 13.62" diameter, 41.65" length, and a net weight of approximately 128.99 lb, enabling accurate lift, mounting, and clearance assessments. The product is offered with a manufacturer-backed limited warranty period to protect asset value and support lifecycle cost forecasting. Specification-backed assembly design and inclusion of installation hardware reduce labor time compared with sourcing individual components, helping fleets return vehicles to service faster. For operations focused on uptime and regulatory compliance, this DINEX SCR assembly delivers a purpose-built emissions control component that aligns with modern EPA requirements and the service expectations of commercial powertrains.
