After Treatment Repairs

Comprehensive After-Treatment System Services

Diesel engines require an efficient after-treatment system to reduce harmful emissions and comply with stringent environmental regulations. Our after-treatment services cover every critical component of this system, helping fleet operators and truck owners maximize vehicle efficiency, reduce maintenance costs and extend engine lifespan.

Diesel Particulate Filter (DPF) Cleaning & Repairs

The diesel particulate filter (DPF) plays a crucial role in capturing and removing soot from exhaust gases. Over time, DPFs accumulate excessive soot and ash, leading to regeneration failures, clogged filters and engine performance issues. Our DPF cleaning service ensures your filter remains free of excessive buildup, helping to improve fuel efficiency and reduce backpressure.

Our DPF Services Include:

• DPF Cleaning: We use advanced cleaning techniques, including bake-and-blow, pneumatic cleaning and ultrasonic cleaning, to restore your filter to optimal condition.
• DPF Regeneration Assistance: If your system fails to regenerate automatically, our team can perform forced regeneration to clear stubborn soot buildup.
• DPF Repairs & Replacements: If cleaning is no longer effective, we offer DPF replacements and repairs to ensure compliance with emissions regulations.

EGR Cleaning and Repairs

The Exhaust Gas Recirculation (EGR) system helps control NOx emissions by recirculating a portion of exhaust gases back into the engine cylinders. Over time, EGR valves and coolers become clogged with carbon deposits, leading to power loss, increased fuel consumption, and engine overheating.

Our EGR Services Include:

• EGR Valve Cleaning: We remove and clean carbon deposits to restore proper airflow.
• EGR Cooler Repairs: If your EGR cooler is clogged or leaking, we provide thorough cleaning and replacement options.
• EGR System Diagnostics: Using state-of-the-art diagnostic tools, we detect faults and prevent future breakdowns.

Selective Catalytic Reduction (SCR) System Repairs

The SCR system reduces nitrogen oxide (NOx) emissions by injecting Diesel Exhaust Fluid (DEF) into the exhaust stream. Faulty SCR components can trigger engine warning lights, cause performance issues, and lead to costly fines for non-compliance.

Our SCR Services Include:

• SCR Catalyst Cleaning & Repairs to maintain efficient NOx conversion.
• DEF Dosing System Inspections to ensure proper DEF injection.
• NOx Sensor Testing & Replacements to prevent false readings and emissions failures.

Benefits of After-Treatment System Maintenance

Proper maintenance of your after-treatment system offers several benefits, including:

• Extended Engine Life: A well-maintained DPF, EGR, and SCR system reduces strain on your engine, preventing costly repairs.
• Fuel Efficiency Improvements: Clean filters and efficient exhaust systems lead to better fuel economy.
• Regulatory Compliance: Keeping emissions systems in top condition helps avoid fines and legal issues.
• Reduced Downtime: Preventive maintenance minimizes unexpected failures and keeps your trucks on the road.
