Chapter 6—Extended Storage
Procedures
Following a few simple procedures will greatly minimize
the risk of corrosion and damage. Corken recommends
the following precautions to protect the compressor
during storage:
1. Drain the crankcase oil and refill with rust inhibiting oil.
2. When a compressor is returned from long-term
storage, the compressor’s nameplate should be
removed and the new oil poured over the crossheads
to ensure good crosshead lubrication at startup.
3. Operate for a few minutes while fogging oil into the
compressor suction.
4. Relieve V-belt tension.
5. Plug all openings to prevent entry of insects and
moisture. (The cylinders may also be protected by the
use of a vapor phase inhibitor, silica gel, or dry nitrogen
gas. If the silica gel is used, hang a tag on the unit
indicating that it must be removed before start-up.)
6. Store in a dry area, off the ground if possible.
7. Rotate the flywheel every two weeks if possible.
8. If possible, store compressor in a climate controlled area.
