Comparison of Drying Methods

Air Drying: Disadvantages (continued)

    • While potentially less expensive than commercial drying, costs for air-drying can include supplies such as absorbent and interleaving materials, energy expenses for dehumidifiers and fans, and additional security.
    •  Costs for staff carrying out recovery actions in place of their regular work can be great.  Staff may also be displaced while workspaces are occupied by drying activities.
    • Though treated in-house, air-drying still allows a chance for disruption of original order.
    • The possibility for mold is ever-present.

    Dehumidification-Drying: Advantages

    • Dehumidification-drying is advantageous if drying damp, but not wet materials.
    • It can be carried out on-site to allow access to materials during the drying process.
    • It holds promise for drying slightly damp items in situ, that is, without removing them from their housings or locations.
    • Drying can also be performed at a vendor’s facility
    •  (Dehumidification-Drying: Disadvantages)
    • But dehumidification results in a distorted product with greater corrosion from metal fasteners.
