Storage
In some cases it may be necessary to store the compressor for extended
periods of several months before placing the unit in operation. When this
is required do the following:
Cover and seal all machine openings to prevent the
entrance of water and dirt.
Cover all openings in open drip proof motors to prevent
the entrance of rodents.
If the storage conditions are below freezing; drain the after cooler,
traps, water-cooled heat exchanges and attendant piping. We do not
recommend outside storage.
Cover with a waterproof tarpaulin that can easily be removed for in-
storage maintenance.
While in storage, every two or three months, rotate the compressor
and motor by hand to prevent flat spots on the bearings that will lead to
premature failure.
At the end of the storage period, follow the uncrating and start-up
procedures. If the unit has been stored for more than eighteen months,
you should contact Compressed Air Systems before restarting the
compressor.
Guidelines
The air pressure drop between the compressor and the point of use is
not recoverable.
Pipe size should be large enough that the pressure drop does not exceed
10% between the air receiver and the point of use.
Arrange the air distribution piping to avoid the following types of strain:
Strains that are due to dead weight of the pipe itself.
Strains that are due to expansion or contraction of the piping due to
temperature.
Strains due to internal pressure within the pipe.
Design inlet and discharge piping for smooth airflow.
Plan for future emergencies and establish an area of the loop to install a
temporary compressor.
Consider a second receiver at the end of the line or opposite side of the
loop.
