Selective Catalyst Reduction (SCR) Systems for Trucks

Read About SCRs and How They Keep You EPA Compliant

Selective Catalyst Reduction systems are essential NOx emission control technologies that inject diesel exhaust fluid (DEF) into your truck's exhaust stream to convert harmful nitrogen oxides into harmless nitrogen and water vapor. When your commercial vehicle's SCR system fails, maintaining EPA compliance while minimizing repair costs becomes critical for fleet profitability.

Advanced SCR Remanufacturing Excellence

DPF360's remanufactured SCR systems undergo comprehensive restoration processes that restore catalyst efficiency and DEF injection performance to OEM specifications. Our specialized remanufacturing facility employs advanced cleaning technologies, catalyst substrate restoration, and precision flow testing to ensure optimal NOx conversion rates essential for emissions compliance.

Each SCR system receives thorough inspection of catalyst substrates, injector components, and mounting assemblies. Our dyno-testing protocols validate proper DEF injection patterns, NOx reduction efficiency, and backpressure characteristics before certification and shipment.

Comprehensive SCR Coverage for Major Truck Manufacturers

Our extensive inventory covers selective catalyst reduction systems for leading commercial truck brands and engine configurations. Whether you operate Volvo trucks, Mack vehicles, Cummins-powered fleets, or other major diesel engine platforms, we maintain the precise OEM replacement SCR systems your vehicles require for continued regulatory compliance.

Each remanufactured SCR system includes:

• Complete catalyst substrate cleaning and restoration
• DEF injector inspection and performance validation
• Comprehensive flow testing and NOx conversion verification
• OEM-equivalent mounting hardware and gaskets
• Direct-fit compatibility for seamless installation
• EPA and CARB emissions compliance certification

Technical Expertise for Complex Emission Systems

SCR system failures can involve multiple components including catalyst substrates, DEF injectors, temperature sensors, and control modules. Our technical support team provides expert guidance for proper system diagnosis, component identification, and installation procedures to ensure optimal aftertreatment system integration.

Understanding the interaction between SCR systems, diesel particulate filters, and diesel oxidation catalysts is crucial for maintaining proper emissions performance. Our specialists help fleet managers and technicians navigate these complex relationships for reliable long-term operation.

Professional Fleet Support and Warranty Protection

We recognize that SCR system downtime directly impacts fleet productivity and compliance status. Our streamlined ordering process and technical support minimize vehicle downtime while our one-year unlimited mileage warranty provides comprehensive protection for your investment.

Our remanufactured SCR systems deliver proven NOx reduction performance at significant cost savings compared to new OEM replacements, helping fleet operators maintain compliance without compromising profitability.
