Euro 4 & 5 DPF Cleaning – Open Filters
Excalibre have developed processes to effectively clean the open type filters found on MAN and Scania Euro 4 & 5 busses and trucks. These filters are designed to be non-blocking however over time they can be come blocked with ash leading to high exhaust back pressures. This in turn results in loss of performance and fuel economy.
We flow test every exhaust on arrival and after the cleaning process to ensure that it is returned to its original flow characteristics.
For heavy block filters we also offer an enhanced clean whereby the units is disassembled and the individual elements cleaned. Where filters are damaged beyond repair, Excalibre offer a refurbishment service.
Euro 4 & 5 SCR Silencer Catalyst Cleaning
AdBlue™ contaminated SCR Silencers
SCR silencers can become blocked with Adblue™ deposits due to poor nozzle atomisation or other dosing related issues. This is turn causes high exhaust back pressure and loss of performance.
Depending on the level of AdBlue™ build up Excalibre can effectively remove this through a controlled chemical washing process and restore the function of the silencer.
SCR Silencer Refurbishment
Where it is not possible to remove the contamination, or where the catalyst has been damaged beyond repair then the silencer can be refurbished by replacing the SCR catalysts.
