Turbocharger Cleaning

Regular water cleaning of the turbine and the compressor reduces the formation of deposits
and extends the time between overhauls. Fresh water is injected into the turbocharger during
operation. Additives, solvents or salt water must not be used and the cleaning instructions in
the operation manual must be carefully followed.
11.1 Turbine cleaning system
A dosing unit consisting of a flow meter and an adjustable throttle valve is delivered for each
installation. The dosing unit is installed in the engine room and connected to the engine with
a detachable rubber hose. The rubber hose is connected with quick couplings and the length
of the hose is normally 10 m. One dosing unit can be used for several engines.
