Cummins Select Catalyst Reduction | OEM: 4394764 SKU: 360-R4394764

Phase 1: Initial Evaluation & Preparation

• Core Evaluation: Every shell and internal substrate is inspected to confirm it has "remanufacturing value" before proceeding.
• Thermal Regeneration: Contaminants and soot are reduced to ash to prepare the unit for deep cleaning.
• Chemical Regeneration: Units undergo a proprietary liquid cleaning and treatment process to restore the active surface area of the internal catalyst.
• Thermal Drying: Components are baked at industry-standard temperatures to ensure they are completely dry and free of moisture.
• Pneumatic Cleaning: Process to ensure the filter is cleaned to 99% of OE Standards.
• Flow test: This critical test ensures OE Standards are met.
• Infrared Light test: This inspection ensures there are no damaged cell or internal cracks.

Phase 2: Advanced Testing & Performance Benchmarks

Rosemount Analytical Testing: Units are placed on a test bench where a Dyno-controlled engine’s exhaust is piped through. Rosemount NDIR (Non-Dispersive Infrared) and FID (Flame Ionization Detector) analyzers measure pollutant conversion in real-time.

Catalyst Efficiency Standards:

• DPF: Must be cleaned to 99% of OE standards.
• DOC: Dyno Performance CO and HC test must meet or exceed 97% of OE standards.
• SCR: Must achieve a NOx reduction of 94% or greater.

Restore™ Performance: The process recovers up to 90% of original catalyst efficiency and up to 100% by replenishing precious metals. 

Phase 3: Compliance & Quality Assurance

• EPA Certification: The facility operates under a registered EPA ID, ensuring all processes meet federal environmental standards.
• Serialized ID & Data Integrity: Every unit is assigned a serialized ID. All testing data is stored on secure servers to maintain historical transparency for each component.
• 2026 Smog Compliance: Only units that pass laboratory-grade conversion tests receive the Quality Seal, guaranteeing they will clear 2026 smog inspections.
• Final Structural Integrity: All bungs are thread-chased, and brackets are repaired to ensure perfect OE fitment before units are sandblasted and painted.
