Canister Storage

Pressurised steel rotor storage containers provide significant protection when used during either shipping or storage. Manufacturing and construction processes enables the storage containers to be stowed vertically. And as a result, the risk of rotor bowing is prevented, that would otherwise occur during long-term horizontal storage. In the horizontal position, the rotor would sag and detrimentally affect API level rotor balance.

Canister Preservation

Although these rotor storage containers are closed structures, there is still potential for contamination from outside air including dust and humidity. Consequently, the steel rotor parts would be in the presence of moisture and react with oxygen causing material corrosion. Due to the gelatinous nature of heavier preservatives, they are difficult and time-consuming to remove from rotors. The premier solution, then, for rotor preservation is a nitrogen purge system. Nitrogen functions as an excellent alternative to physical coatings as removal is not required prior to operation. Accordingly, rotor storage containers are frequently equipped with a nitrogen purge system.

The nitrogen purge system, purges atmospheric air. It then replaces the volume of sealed rotor storage containers with commercially pure nitrogen. The rotors are then suited for long-term storage without excessive surface preservation.

These rotor storage containers ensure companies have easy access to essential spare parts. These parts need to be kept on hand for an indeterminate amount of time. They are often difficult to obtain quickly.
