Ultrasonic Cleaning 

WHAT IS ULTRASONIC CLEANING?

A. In a process termed "cavitation", micron-size bubbles form and grow due to alternating positive and negative pressure waves in a solution. The bubbles subjected to these alternating pressure waves continue to grow until they reach resonant size. Just prior to the bubble implosion, there is a tremendous amount of energy stored inside the bubble itself.

Temperature inside a cavitating bubble can be extremely high, with pressures up to 500 atm. The implosion event, when it occurs near a hard surface, changes the bubble into a suction jet about one-tenth the bubble size, which travels at speeds up to 400 km/hr away from the hard surface. With the combination of pressure, temperature, and velocity, the jet frees contaminants from their bonds with the substrate. Because of the inherently small size of the jet and the relatively large energy, ultrasonic cleaning has the ability to reach into small crevices and remove entrapped soils very effectively.

THIS MAKES ULTRASONIC CLEANING THE PERFECT SYSTEM FOR CLEANING DIESEL PARTICULATE FILTERS.

Don't think what we do is the same as our competition ... it's not. Our multi-stage DPF Cleaning System is actually a full reconditioning of your DPF. Nobody in the U.K. goes to the extremes that the DPF Cleaning Co does to make sure we do it right and save you money. You'll find out more as you read through our website. We've cleaned over 4000 DPF's in the last 5 years for the general public and return customers such as car dealerships, commercial vehicle companies, warranty companies and councils. We're also used by over 200 local garages nationwide.

Why us? Guaranteed clean, dealer lever diagnostic systems for all makes and all models, a knowledge base second to none with fast turnaround and excellent customer care. 

If you see your DPF light on and it stays on, it means your DPF isn't regenerating. If you continue to drive with the light on, you are risking not just damaging the DPF but also the turbo. This can lead to repair costs of £3000 and above. Ultrasonic DPF Cleaning is the only real alternative to a DPF replacement and can save you serious money.

If a vehicle fails to regenerate the diesel particulate filter will become blocked and the engine management or DPF warning light will illuminate. The failure to regenerate can be caused by the style of driving or type of journeys covered not allowing the vehicle to reach the parameters required for regeneration or due to the failure of a sensor or component associated with the regeneration process.

It is paramount that the reason the original diesel particulate filter became blocked is correctly diagnosed and rectified prior to installation of a replacement unit. Once this has been done and the new unit fitted the vehicle must be set up correctly with compatible diagnostic equipment. Failure to set up the vehicle correctly after installation will almost certainly lead to the replacement DPF becoming blocked.

We're often asked what's involved, please watch the short video to get an insight into the 6 hour process that includes, removal, ultrasonic DPF cleaning and software updates using our state of the art Dealership Level Diagnostics systems, which updates the dealership of the work we've done on your car.

100% MOT Safe. Comes with a certificate of cleanliness, engraving to the exhaust and your registration is registered with us for full "tracking" and remember, because your DPF is nearly 100% clean, it's less likely to fail the new MOT emissions tests than those cleaned by our competition ... we know all about the new MOT emissions tests because we're an authorised MOT Station.
Don't confuse what we do with "methods" that you've tried before, our system works. We remove the DPF from its casing for cleaning, we then clean the DPF in an ultrasonic bath until it's clean, then we weld the DPF back into it's case, test it for flow and return it to you.
Over 35% of DPF's that come to us have apparently been cleaned elsewhere.
Ultrasonic DPF Cleaning is the "only system that works across the board", cars, vans, commercial vehicles such as lorries, tractors and plant. If you're having issues with your DPF, call us today, we have the solution.

Ultrasonic DPF Cleaning £189 + VAT (Free collection and delivery of your DPF within a 35 mile radius)

DPF Diagnostics £55 (Free if you have full clean done by us)

*The Cheapest in the UK for Ultrasonic DPF Cleaning.

Removal is not a legal option

It is suggested from time to time that the answer to failed DPF regeneration is get the DPF removed from the exhaust system rather than pay to get it repaired/renewed.  Indeed there are companies advertising just such a service including reprogramming of the engine management software, but is it legal?

DPFs are fitted to meet European emissions regulations designed to reduce vehicle emissions of particulate matter (soot) associated with respiratory disease and cancer.

According to the Department for Transport, it is an offence under theRoad vehicles (Construction and Use) Regulations (Regulation 61a(3)) to use a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet. Removal of a DPF will almost invariably contravene these requirements, making the vehicle illegal for road use.

Insurance

You must notify your insurer if the vehicle is modified but such a modification could in turn invalidate any insurance cover because it makes the vehicle illegal for road use.

MOT

From February 2014 the inspection of the exhaust system carried out during the MOT test will include a check for the presence of a DPF. A missing DPF, where one was fitted when the vehicle was built, will result in an MOT failure.

With an original equipment DPF removed from the exhaust the car may or may not pass an MOT smoke test - a Euro V (September 2009 diesel) is more likely to fail than one designed to comply with earlier emissions standards.

My E Class Mercedes was diagnosed as having DPF issues and I was advised that a new DPF was required, i'm sure you can imagine the cost!

After some digging around I found this place and i'm delighted I did. The car is back to it's old self, they did a perfect job. Highly Recommended!

What is a DPF?

The Diesel Particulate Filter (DPF) is housed in the exhaust and is designed to capture the soot particles emitted from modern diesel engines.

Sadly, many of the DPF equipped cars are developing problems due to the DPF either failing, clogging up or just failing to carry out a regeneration properly.

This can be down to the age of the vehicle, mileage or could be simply down to the driving style of the owner. Whatever it is, when a DPF warning light illuminates it often means a pretty expensive bill is on its way. 

If this does happen, there are some upsides. A DPF clean can increase your vehicles fuel economy, performance and decrease the likely hood of a breakdown or your car ending up in "limp mode" and save you a pretty large sum of of money if the time has come to replace your Diesel Particulate Filter which can be considered normal for some car manufacturers at 60 to 75 thousand miles and costing upwards of a £1000 and over to replace.

Is my DPF covered under warranty?

The DPF is seen as a consumable by many manufacturers and warranty providers. The cost of replacing or regenerating the filter is normally not covered but we would suggest seeking advice if you are experiencing DPF related issues.

What is Ultrasonic DPF Cleaning?

Ultrasonic cleaners employ oscillating sound pressure waves at frequencies beyond those perceptible by the human ear (Ultrasound). As the soundwaves act on the tank and agitate the contained liquid, cavitation (the implosion of tiny air bubbles within the liquid) is induced.

This acts against contaminants adhered to objects contained in the vessel, separating the two much more gently, efficiently and precisely than would be the case with conventional cleaning methods aided by brushes or solvents.

The ultrasonic cleaning process is used in conjunction with solutions in suitable carrier liquids (often water). As the ultrasonic-induced cavitation occurs, the effectiveness of the aqueous solution is greatly improved to deliver an outstanding clean.

Ultrasonic cleaning is the ideal solution for DPF cleaning, especially forFleet Car DPF Cleaningit leaves no contamination or build-up on the DPF filter meaning essentially, the DPF after cleaning is "as new".

What we don't do is "DPF Removal" or what's commonly known as "DPF Delete". To find out why, click on the button below.
