EGR Cooler & Valve Cleaning
Our advanced filter cleaning machines can extract all soot from any EGR valves and coolers on the market, as well as SCR assemblies that have become contaminated due to a breached DPF.
With the help of specially calibrated solution tanks and progressive ovens that can reach incineration temperatures of 1200 degrees and more we have successfully removed diesel soot from an SCR that has become contaminated due to a breached DPF. When a DPF cracks and dumps un-incinerated soot into the SCR it will give you a code for low conversion. We can salvage any SCR that has this condition and do so for many shops that need this repair.
EGR valve assembly:
- The EGR Valve is weighed and then flow tested to determine the among of any restrictions.
- The EGR Valve is then High Pressure Compressed Air/High Pressure Vacuum air cycled in our Filter Cleaning Machine until all of the soot has been extracted.
- Once the cycle is complete, we then weigh, and flow test the EGR Valve again to determine the amount of restriction that was extracted during the process.
- The EGR Valve is then disassembled and the parts are put into our ultrasonic bath machine and cycled until all of the soot and buildup has been removed. (2 Days on average)
- The EGR Valve is then high pressure compressed air cycled in our cleaning machine to dry off the EGR Valve components. The EGR Valve is then re-assembled and checked for performance according to manufacturer’s specifications and ultrasound tested for cracks.
- Once complete, the EGR Valve is flow tested at 1500 cfm (reduced highway speed) and compared to the manufacturers specifications for that particular EGR Valve.
EGR cooler:
- The Diesel Exhaust Gas Recirculation Cooler (EGR) is weighed and then flow tested to determine the among of any restrictions.
- The EGR is then High Pressure Compressed Air/High Pressure Vacuum air cycled in our Filter Cleaning Machine until all of the loose soot has been extracted.
- Once the cycle is complete, we then weigh and flow test the EGR Cooler again to determine the amount of restriction that was extracted during the process.
- It is then placed into one of our High Temperature Ovens to bake for three (3) hours at the “Diesel Soot Incineration” Temperature in order to incinerate any possible soot that could be trapped in the passageways.
- The EGR Cooler then undergoes another High Pressure Compressed Air/High Pressure Vacuum air cycle to extract any of the incinerated soot.
- We then submerge the EGR Cooler in our Testing Tank and is pressurized to inspect for air leaks. It is then placed to air dry and is monitored our Leak Down Test bench for two (2) hours for pressure loss.
- Once cleaning is complete, we Flow Test the EGR Cooler at 2000 cfm (highway speed) and compare to the Manufacturer’s Specifications for that particular Model.
Catalytic Mufflers
Our advanced cleaning process removes all carbon deposits from your muffler and will restore the gas flow that the exhaust system was designed for.
- The Catalyst Muffler is weighed and then flow tested to determine the among of any restrictions.
- The Catalyst Muffler is then High Pressure Compressed Air/High Pressure Vacuum air cycled in our Filter Cleaning Machine until all of the loose soot has been extracted.
- Once the cycle is complete, we then weigh and flow test the Catalyst Muffler again to determine the amount of restriction that was extracted during the process.
- It is then placed into one of our High Temperature Ovens to bake for eight (8) hours at the “Diesel Soot Incineration” Temperature in order to incinerate any possible soot that could be trapped in the passageways.
- The Catalyst Muffler then undergoes another High Pressure Compressed Air/High Pressure Vacuum air cycle to extract any of the incinerated soot.
- We then submerge the Catalyst Muffler in our Testing Tank and is pressurized to inspect for air leaks due to Stress Cracking.
a) Any Cracks are welded
b) It is then placed to air dry and is monitored our Leak Down Test bench for two (2) hours for pressure loss. - Once cleaning is complete, we Flow Test the Catalyst Muffler at 2000 cfm (highway speed) and compare to the Manufacturer’s Specifications for that particular Model.
Charge Air Coolers
Our equipment can safely clean carbon or sulphurous deposits that cling to the fins of the CAC over time, helping increase its efficiency and extend its lifetime.
- The Air Charge Cooler is weighed and then flow tested to determine the among of any restrictions.
- The Cooler is then placed in our Cooler Cleaning Machine to undergo a Compressed Air/Pressure Hot Solution Cycle to remove/extract all the oil and soot buildup.
- We then weigh and flow test the Cooler again to determine the amount of oil and soot that was removed.
- At that time, the Cooler is then put into one of our Dry Out Ovens to be Thermally Heat Treated at four (4) pre-programmed temperature levels.
a) The Cooler is inspected during the dry-out cycle for vapors from the incinerating oil.
b) The cycle is complete once there are no remaining oil vapors.
c) Any incinerated oil residue is then compressed air and vacuum cycle removed. - The Cooler is then pressurized at 12 lbs. and inspected for leaks. A Leak Down Test is performed.
- Any Cracks in the housing or Tubes are welded and a secondary Leak Down Test is performed.
- For the Final Step in the Process, the Cooler is then Flow Tested at 2000 cfm (highway speed), and compared to the manufacturer’s specifications for that particular Air Charge Cooler Model.
DEF Decomposition Reactors
We employ a special cleaning process to remove all solid urea deposits in the after-treatment system’s decomposition reactor, caused by incomplete decomposition of diesel exhaust fluid.
- The DEF Reactor is weighed and then flow tested to determine the among of any restrictions.
- The DEF Reactor is then High Pressure Compressed Air/High Pressure Vacuum air cycled in our Filter Cleaning Machine until all of the loose Dried DEF Fluid build-up has been extracted.
- Once the cycle is complete, we then weigh and flow test the DEF Reactor again to determine the amount of restriction that was extracted during the process.
- It is then placed into one of our High Temperature Ovens to be Thermally treated at 4 pre-programmed temperature levels and enriching the last level with pure oxygen to slowly degrade the DEF fluid deposit until it turns to extractable powder.
- The DEF Reactor then undergoes another High Pressure Compressed Air/High Pressure Vacuum air cycle to extract any of the degraded DEF Fluid Deposits/powder.
- Once cleaning is complete, we Flow Test the DEF Reactor at 2000 cfm (highway speed) and compare to the Manufacturer’s Specifications for that particular Model.
