ADVANCED CLEANING METHODS & SYSTEMS
AQUEOUS DPF CLEANING SYSTEM
Advanced Deep Cleaning Technology
EcoLine offers advanced aqueous DPF cleaning using a computer-controlled cleaning system designed to deliver deep internal cleaning without damaging the filter substrate or precious metals.
Our process uses recirculated water flow and specialized cleaning solutions to remove soot, ash and contaminants throughout the entire filter while restoring proper airflow and performance.
FAST TURNAROUND SERVICE
AQUEOUS DPF CLEANING SYSTEM
Deep Cleaning Technology. Fast Turnaround.
When a diesel particulate filter becomes restricted by soot, ash, and contaminants, restoring proper airflow requires more than a simple rinse. EcoLine's Aqueous DPF Cleaning System uses a computer-guided cleaning process designed to thoroughly clean the entire filter structure while protecting its internal components.
Unlike traditional cleaning methods, this advanced system combines a specialized pre-soak treatment, high-volume recirculated water cleaning, accelerated drying, and post-cleaning inspection to remove contaminants throughout the filter from edge to edge. The continuous low-pressure, high-volume water flow reaches deep into the filter channels, helping restore performance without damaging the substrate or precious metals contained inside the DPF.
One of the biggest advantages of this process is speed. Through a combination of automated washing and accelerated drying technology, many filters can go from dirty to clean and dry in less than two hours, helping reduce downtime and get trucks back on the road faster.
How the Process Works
1. Pre-Soak Treatment
A specialized cleaning solution is applied to loosen soot, ash, and debris trapped inside the filter.
2. Computer-Guided Cleaning
The filter is cleaned using a controlled, high-volume recirculated water system that flushes contaminants throughout the entire substrate.
3. Accelerated Drying
The filter is dried using a dedicated drying system designed to remove moisture quickly and efficiently.
4. Inspection & Verification
Flow, condition, and overall filter performance are verified before reinstallation.
Ideal For
- Heavily contaminated DPF filters
- Fleet maintenance programs
- Preventive DPF service
- Fast-turnaround cleaning needs
- Customers looking to maximize filter life
Benefits
- Deep edge-to-edge cleaning
- Non-destructive cleaning process
- Protects valuable catalyst materials
- Fast turnaround times
- Reduced downtime
- Cost-effective alternative to replacement
- Helps restore airflow and performance
THERMAL DPF CLEANING SYSTEM
High-Temperature DPF Restoration
Our thermal DPF cleaning system is designed to restore heavily restricted diesel particulate filters using a controlled high-temperature cleaning process combined with advanced pulse-air technology.
This process helps remove hardened soot, ash buildup and contaminants that can reduce airflow, increase regenerations and affect overall engine performance.
THERMAL DPF CLEANING SYSTEM
Advanced Restoration for Severely Restricted Filters
When a DPF becomes heavily loaded with soot and ash, restoring performance often requires a more intensive cleaning approach. EcoLine's Thermal DPF Cleaning System uses a proven multi-step process that combines controlled thermal regeneration, cooling, inspection, and high-velocity air cleaning to remove contaminants and recover filter performance.
This process is specifically designed for diesel particulate filters and allows multiple filters to be processed efficiently while maintaining consistent cleaning quality. The thermal stage breaks down accumulated soot inside the filter, while the pulse cleaning stage removes loosened ash and debris from deep within the substrate.
For filters that have experienced significant restriction, this method provides an effective solution to restore flow, extend service life, and avoid unnecessary replacement costs.
How the Process Works
1. Initial Inspection
The filter is inspected and evaluated to determine its condition and cleaning requirements.
2. Controlled Thermal Regeneration
The DPF is placed in a specialized thermal cleaning system where accumulated soot is safely reduced through a controlled heating cycle.
3. Cooling Process
The filter is properly cooled before moving to the next stage to protect its structure and ensure safe handling.
4. Pulse Air Cleaning
A high-velocity air pulse cleaning system removes ash and contaminants loosened during the thermal process.
5. Flow Testing & Verification
The filter is tested to verify airflow improvement and overall cleaning effectiveness.
Ideal For
- Severely restricted DPF filters
- High-mileage trucks
- Fleet maintenance operations
- Heavy-duty diesel applications
- Filters with significant ash accumulation
Benefits
- Effective ash removal
- Restores filter flow capacity
- Extends DPF service life
- Reduces replacement costs
- Suitable for high-volume cleaning operations
- Proven multi-step restoration process
- Helps return trucks to peak operating performance

Preventive Diesel Emissions Maintenance
EcoLine is an authorized Diesel Force dealer providing advanced preventive maintenance solutions for modern diesel engines and emissions systems.
Our Diesel Force services are designed to help reduce downtime, minimize costly repairs and improve overall engine performance by cleaning and maintaining critical components before severe failures occur.
Diesel Forceâ„¢ Preventive Cleaning
Advanced Emissions System Cleaning Without DPF Removal
As an authorized Diesel Forceâ„¢ dealer, EcoLine offers a comprehensive preventive cleaning service designed to restore efficiency throughout your diesel engine's emissions system without removing the DPF in many applications.
Using specialized Diesel Forceâ„¢ equipment and cleaning solutions, our technicians clean critical emissions components including the EGR circuit, intake system, turbocharger exhaust side, DOC, and DPF. The system delivers a high-volume cleaning foam through the engine's emissions pathways, helping remove carbon, soot, and deposits that restrict airflow and reduce performance.
Unlike traditional repairs that often focus on replacing expensive components, this preventive maintenance process is designed to help maintain and restore the emissions system before major failures occur. It can significantly reduce regeneration frequency, lower maintenance costs, improve engine efficiency, and extend the life of critical emissions components.
What Components Are Cleaned?
Our Diesel Forceâ„¢ service helps clean and restore:
- EGR Valve
- EGR Cooler
- Intake & Induction System
- Turbocharger Exhaust Side
