Cleaning the compressor during
operation
Cleaning method
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 or the suction branch.
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 degree of contamination is not too high.
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.

In the case of V-engines with several turbochargers on each engine, we
recommend parallel cleaning of the compressors. This cleaning process is
faster and the risk of turbocharger surging is reduced.
