When is desiccant replacement necessary in the lay-up procedure?

Desiccant replacement is necessary when humidity levels exceed 50% during the lay-up procedure because desiccants are specifically designed to absorb moisture from the air to prevent corrosion and damage to equipment. When humidity levels rise above this threshold, the effectiveness of the desiccant diminishes, which can compromise the protective environment established during the equipment's lay-up. Maintaining humidity below this level is critical to ensuring that the desiccant can continue to perform its function effectively.

This will help protect the equipment, as excessive moisture can lead to rust and other forms of deterioration. Therefore, monitoring humidity levels and replacing the desiccant when they exceed 50% is an essential part of the maintenance strategy for safeguarding machinery during periods of inactivity.
