Wet cleaning methods
Process with short water injection time (3 x 30 seconds cleaning)
The cleaning process with short water injection time is used for turbo-
charger designs without additional sealing by means of C-rings.
The process is based on the principle of thermal shock in combination
with a subsequent flushing phase.
Process with long water injection time (10 minutes cleaning)
The cleaning process with a long water injection time is used for turbo-
charger designs with additional sealing by means of C-rings.
Based on a 10-minute injection phase, this cleaning process utilises the
water solubility of the dirty deposits.
Choice of cleaning method
If you need information about the choice of cleaning method (short /
long), you can contact the engine builder or an official ABB Turbo-
charger service station.
