We recommend that a desiccant be replaced once every three years for open-cycle systems and once every two years for closed-cycle systems. A desiccant may degrade more quickly depending on the environment where it is used. Dew point temperatures offer a good indication for when to replace your desiccant.
How often should you change desiccant?
Replacement of desiccant beads is recommended every two years.
Can you microwave desiccant bags?
Do not go over 300-degrees in the standard oven or 900-watts in a microwave. You will damage the silica gel and it will lose its absorbency. Heating the packets over 245-degrees will damage the packaging.
