Long-term storage of replacement low-pressure and high-pressure stages or
replacement cartridge groups
ABB Turbocharging will prepare low-pressure and high-pressure stages or cartridge groups
for long-term storage if requested in the purchase order. The package is equipped with a hy-
grometer (see illustration).
Fig.18: Package with hygrometer
Every 6months, the following measures are required:
u Check the hygrometer(02) in the sight-glass. There is an opening(01) in the wooden
crate which allows this check to be carried out. When the display field has changed colour
at the 70% level, the maximum permissible humidity has been exceeded. In this case, the
low-pressure or high-pressure stage or the cartridge group must be checked and repack-
aged by an ABB Turbocharging Service Station.
u Check the package for damage. If the package is damaged, the low-pressure or high-
pressure stage or the cartridge group must be checked and repackaged by an ABB Tur-
bocharging Service Station.
After every 3 years, the following steps must be carried out by an ABB Turbocharging Service
Station:
¡ Checking the component
¡ Replacing the desiccant
¡ Repackaging the component.
Replacement components which are ready for operation
If the 70% field of the hygrometer(02) has not changed colour and the package is not dam-
aged, the replacement low-pressure or high-pressure stage or the replacement cartridge
group can be put into operation without previously having been checked by an ABB Tur-
bocharging Service Station.
