Accurate Industrial remanufactures diesel emissions systems - including DPFs, SCRs, DOCs, and complete catalyst assemblies - at enterprise scale. Our EPA-compliant remanufacturing process restores Tier 4 systems to OEM-level performance through documented testing, rigorous quality control, and full traceability.
We remanufacture the full range of diesel aftertreatment components for Tier 4 on-road and off-road equipment. Each system is processed through a controlled, fully documented remanufacturing workflow; never batch-processed or approximated. Every unit is individually inspected and verified to meet OEM specifications.
Tier 4 Final represents the U.S. Environmental Protection Agency's most stringent emissions standard for off-road diesel equipment, including generators, compressors, excavators, and similar machinery. These systems rely on advanced emissions control technologies such as Diesel Oxidation Catalysts (DOC), Selective Catalytic Reduction (SCR), Diesel Particulate Filters (DPF), and Ammonia Catalysts (NH₃) to meet compliance requirements.
While effective, these components are complex and costly to replace when they fail. Our remanufacturing program restores Tier 4 aftertreatment systems to OEM-equivalent performance at a significantly lower cost than new replacement units. The result is reduced downtime, continued regulatory compliance, and extended equipment life across your fleet.
Each unit goes through a controlled five-step remanufacturing process, with every stage documented, tested under real conditions, and certified before it leaves our facility. We process each unit individually.

Accurate Industrial works closely with some of the largest equipment rental and fleet operations in the country. This is high-volume, enterprise-level work, and our processes are designed to support it reliably and at scale.
We didn't build our industrial program around one-off projects. From the beginning, our focus has been on developing a disciplined, repeatable process capable of supporting enterprise-scale production without compromising quality. Every system we use is designed to meet the documentation, performance, and compliance standards required by national partners, ensuring consistency, reliability, and scalability at every stage of delivery.
Whether you manage a Tier 4 fleet, operate an equipment rental business, or are seeking a reliable emissions systems partner, we welcome the opportunity to connect and explore how we can support your needs.
