At what temperature should a silica gel dryer be heated to reactivate it?

• A. 200 Deg. F
• B. 350 Deg. F
• C. 450 Deg. F
• D. 500 Deg. F

Answer: (C)

Silica gel is commonly used as a desiccant to absorb moisture, and it needs to be periodically reactivated to restore its drying effectiveness. The optimal temperature for reactivating silica gel typically falls within a specific range to ensure that the moisture trapped in the gel is effectively driven off without damaging the silica itself. Heating the silica gel to around 450 degrees Fahrenheit effectively evaporates the absorbed moisture. At this temperature, the heat allows for the release of water vapor, enabling the gel to regain its moisture-absorbing capacity. This process ensures that the silica gel is ready for reuse in moisture-sensitive applications, making it a vital practice for prolonging the life of the desiccant material. Choosing the correct reactivation temperature is crucial, as temperatures that are too low may not adequately drive off the absorbed moisture, while excessively high temperatures can risk damaging the silica gel structure, potentially decreasing its effectiveness.
