OE-level performance with advanced catalyst technology and modular construction—engineered for maximum durability and serviceability.
Optimized flow dynamics and efficient regeneration processes help reduce fuel consumption, maintenance needs, and total cost of ownership.
Confidence comes standard. Every Dinex OneBox is covered by a 3-year warranty, reflecting our commitment to quality and long-term performance.
A Dinex OneBox is engineered to channel exhaust gases through a complete series of emission control technologies—effectively removing harmful pollutants and meeting the toughest EPA standards.
Sounds complicated? Don’t worry. Dinex has over 15 years of experience designing and manufacturing complete aftertreatment systems for some of the world’s leading OEMs. Using in-house developed technologies, advanced simulations, and rigorous real-world testing, we ensure each system delivers OE-level performance, durability, and compliance.
Our OneBox solutions feature a smart, modular design for easier servicing and lower maintenance costs—without compromising on performance. Backed by a 3-year warranty, Dinex OneBox units deliver the quality, reliability, and value today's fleets demand.
Raw exhaust gas coming from the engine contains carbon monoxide (CO), hydrocarbons (HC), particulate matter (PM), and nitrogen oxides (NOx).
1. Diesel Oxidation Catalyst (DOC):
The DOC burns harmful CO and HC pollutants and generates additional heat. This heat is critical for supporting downstream aftertreatment processes.
2. Diesel Particulate Filter (DPF):
The DPF traps and burns microscopic particulate matter (PM), reducing over 99% of solid particle emissions.
3. DEF Hydrolysis Chamber:
Diesel Exhaust Fluid (DEF) is injected and hydrolyzed, preparing it to react with the NOx gases.
4. Selective Catalytic Reduction (SCR) Catalyst:
In the SCR catalyst, the prepared DEF reacts with NOx gases, converting them into harmless nitrogen (N₂) and water vapor (H₂O).
Throughout the system, sensors monitor and control temperature, NOx concentration, and backpressure—ensuring the process operates efficiently and emissions remain compliant.
The result?
Up to a 95% reduction in NOx emissions and more than 99% reduction in particulate matter, keeping your truck cleaner, more efficient, and fully EPA compliant.
When replacing your OneBox, it's strongly recommended to also replace key components like sensors, mechatronics, and DPFs to ensure optimal system performance and long-term reliability.
At Dinex, we make it easy. You can choose a OneBox that’s fully loaded with DPFs (including clamps and gaskets), or opt for an unloaded version without DPFs—whichever fits your operation best.
Need more? We also offer convenient mechatronics kits designed to pair with your OneBox replacement, so you can get everything you need in one go.
Access everything you need to support your OneBox and aftertreatment system: browse our latest catalog, download the DPF installation guide, and get expert troubleshooting tips—all in one place.
