8 Storage of compress ors
8.1 Shutdown
All compressors are protected against corrosion at the
factory for transport and for brief storage before
commissioning.
If the compressors are to be stored for period
exceeding six months, additional precautions must be
taken.
Compressors which are to be shut down for a lengthy
period must also be protected from corrosion.
Since corrosion occurs more quickly in damp
atmospheres than in dry conditions, it is not possible to
specify a maximum permissible standstill time which will
apply in all cases.
Note
The following aspects must be taken into account for
storage of storing compressors.
The compressor should be stored in a dry building
which should be heated if possible. This is particularly
true during the months of winter.
The coolant is to be completely drained where there is
a risk of frost (t < 1°C) (compressor stage, coolers,
system containers, water filters, storage containers,
RO unit, lines, valves).
If there is a risk that the temperature will fall or rise
above the limits of -10 °C/14 °F to +65 °C/149 °F , the
electrical controller must be removed and stored in
ambient temperatures of +5 °C/41 °F to +30 °C/86 °F.
