How long should equipment be dried in a vented oven at a temperature of 130°F?

Drying equipment in a vented oven at a temperature of 130°F is an important step in the corrosion control process, especially when dealing with avionics components. The recommended duration of 3 to 4 hours is specified to ensure that moisture is completely removed from the equipment without risking damage from excessive heat.

During the drying process, the heat facilitates the evaporation of moisture while the ventilation ensures that the humid air is expelled, preventing any moisture from condensing back onto the equipment. If the drying period is too short, residual moisture can lead to corrosion, which is detrimental to avionics reliability and functionality. Conversely, extending the drying time beyond 4 hours could pose a risk of thermal damage to sensitive components.

Therefore, the time range of 3 to 4 hours strikes a balance between effective drying and safeguarding the integrity of the equipment, making it essential for proper corrosion control practices within avionics maintenance.
