ABB turbochargers
Engines equipped with TPL turbochargers are delivered with an automatic cleaning system,
which comprises a valve unit mounted in the engine room close to the turbocharger and a
common control unit for up to six engines. Cleaning is started from the control panel on the
control unit and the cleaning sequence is then controlled automatically. A flow meter and a
pressure control valve are supplied for adjustment of the water flow.
The water supply line must be dimensioned so that the required pressure can be maintained
at the specified flow. If it is necessary to install the valve unit at a distance from the engine,
stainless steel pipes must be used between the valve unit and the engine. The valve unit should
not be mounted more than 5 m from the engine. The water pipes between the valve unit and
the turbocharger are constantly purged with charge air from the engine when the engine is
operating above 25% load. External air supply is needed below 25% load.
