Storage Of Compressors; Decommissioning - Gardner Denver L Series Original User And Service Manual

9.1

Decommissioning

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.
NOTICE
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 < 34°F) (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 14 °F to 149 °F , the electrical
controller must be removed and stored in ambient temperatures of 41 °F to 86 °F.
