Cleaning of the compressor during operation is carried out using the
cleaning method described in the following:
Wet cleaning
This cleaning method has been tested and approved by ABB Turbo Sys-
tems.
To clean the compressor stage during operation, water is injected in front
of the compressor wheel through an injection pipe fitted in the filter silenc-
er.
The water does not act as a solvent, but the dirt deposit is removed by the
mechanical impact of the droplets. This is a very suitable process, provid-
ed that the build-up of dirt deposits is not too advanced.
Corrosion and deposits when cleaning
Damage and impairment of turbocharger parts due to salt water and
cooling water additives
Don't use salt water for cleaning, but only clean fresh water.
If several turbochargers are installed on one engine, we recommend
cleaning the turbocharger compressors one after the other.
Principle of wet cleaning
Cleaning more than one
turbocharger compressor
