The Science of True Filter Restoration

DPF360’s Restore™ process isn’t just another cleaning—it’s a full-system revival built to outperform anything in the industry. While standard methods only sweep away surface soot, Restore™ goes deeper with a proprietary multi-stage chemical extraction that targets phosphate buildup, oil ash, and catalyst-poisoning compounds basic cleaning can’t touch. Then we take it further by replenishing the precious metals lost during service, bringing catalyst coatings back to true OE levels and delivering up to 90% greater performance. This is the difference between a filter that’s been cleaned… and a filter that’s been restored.

Multi-Step Chemical Extraction

The Restore Process selectively removes phosphate deposits, sooty oils, and deactivating poisons, all without harming the original active catalyst materials.

Precious Metal Restoration

During the process, any precious metals lost in previous service are replaced, restoring the catalyst coatings to original OE metal levels.

Heat Treatment Performance Boost

Finally, multiple heat treatments are applied, resulting in up to 90% greater performance and ensuring the DOC runs like new.

Frequently asked questions
Signs of any deteriorated or non-functioning DOC

Phosphate materials and other catalyst poisons latch onto the catalyst surface, gradually masking the active layer and reducing its ability to interact with exhaust gases. Over time, these contaminants migrate deeper into the coating, further deactivating the catalyst.

As the buildup grows, the DOC can begin to clog and restrict exhaust flow. Once performance drops below its operating threshold, it can no longer keep itself clean or support reliable DPF regeneration—leading to higher backpressure, poor efficiency, and avoidable downtime.
What is The Critical Role of the Diesel Oxidation Catalyst (DOC) in Reliable Particulate Filter Regeneration

The Diesel Oxidation Catalyst (DOC) is a core emissions-control component—and a major driver behind consistent, reliable particulate filter regeneration.

When DOC performance begins to drop, emissions rise, regenerations become incomplete, and the particulate filter is pushed toward premature failure.

A properly functioning DOC performs two essential jobs. First, it oxidizes and “scrubs” harmful diesel exhaust emissions. Second, in systems equipped with a Particulate Filter, the DOC elevates exhaust gas temperatures and increases nitrogen dioxide (NO₂) concentration. These two outcomes are vital for dependable filter regeneration.

Regeneration typically begins when the engine’s electronic fuel system introduces additional fuel downstream. That unburned fuel reacts aggressively across the catalyst surface, generating the heat and NO₂ needed to burn off accumulated soot inside the filter.

However, when the DOC is underperforming, it cannot generate the required heat. Without sufficient exhaust temperature—and without the proper NO₂ balance—the Particulate Filter simply cannot regenerate. Left unaddressed, the filter loads with soot, plugs, and ultimately fails.
How Does Phosphate Contamination Affect DOC Performance?

Phosphate contamination is the leading cause of DOC deterioration and loss of activity. These deposits bond tightly to the catalyst surface, gradually covering the active sites and preventing proper interaction with exhaust gases. Over time, contaminants and catalyst poisons penetrate deeper into the coating, further deactivating the catalyst and, in severe cases, clogging the substrate and restricting exhaust flow. Once DOC performance drops below critical operating levels, it can no longer sustain its own reactions or generate the heat and NO₂ required for reliable particulate filter regeneration.
Why Is DOC Restoration Critical for Particulate Filter Performance?

The Diesel Oxidation Catalyst (DOC) is vital for particulate filter regeneration. It raises exhaust gas temperatures and boosts nitrogen dioxide (NO₂) levels, both of which are critical for burning off accumulated soot during regeneration cycles. When the engine injects extra fuel for regeneration, the catalyst must generate sufficient heat to complete the process. A low-performing DOC cannot reach these temperatures, leading to incomplete regenerations and eventual filter failure. Our restoration process restores DOC efficiency, ensuring consistent heat generation, reliable filter regeneration, and long-term system performance.

Maximize Fleet Efficiency with DPF360 Restore™

DPF360’s Restore™ technology gives fleet operators a cost-effective alternative to costly DOC replacement while ensuring peak emission system performance. By restoring DOCs to near-new condition, our process extends component life, reduces downtime, and keeps fleets EPA-compliant. Fleets benefit from fewer regeneration issues, lower fuel consumption during regen cycles, and significant savings compared to buying new components. This proven technology keeps trucks running efficiently while supporting environmental compliance.

Restoring Power: The Impact of DOC Rehabilitation

Fleet operators can expect significantly improved performance from Diesel Oxidation Catalysts (DOCs) after our full restoration process. Our multi-step chemical extraction removes all embedded contamination, and precise heat-treating restores catalyst activity to up to 90% of original performance levels.

These improvements deliver measurable, real-world benefits:

  • Consistent and reliable DPF regeneration
  • Lower emissions and cleaner engine operation
  • Fewer active regeneration cycles
  • Extended DPF and DOC service life
  • Reduced maintenance frequency and operating costs

Comprehensive before-and-after testing confirms that restored DOCs once again perform to original equipment specifications, giving fleets OEM-level results without OEM-level replacement costs.
