ABB HT569759 Operation Manual page 2

Operating condition and replacement intervals
The operational limits for the turbocharger nBmax, tBmax, nMmax, tMmax, inspection- and replacement intervals for the compon-
ents concerned on the rating plate are valid for the operational mode and compressor inlet condition, which has been agreed upon
between the engine builder and ABB.
Note:
Replacement intervals of components depends on the load profi le, turbine inlet temperature, suction air temperature and
turbocharger speed. In case the operation conditions differs signifi cantly from what is considered to be normal for the cur-
rent application, it is recommended to contact ABB for a re-calculation of replacement intervals. Frequent load alterations,
high temperatures and high speed lower the life of components.
Unless otherwise agreed, the application limits nMmax, tMmax are valid for the test operation for a limited time.
