Drying Desiccant

[moldingppm]

Anyone here dry out their dryer desiccant to recharge it? We have a dryer that is not drying well that the desiccant hasn't been touched since it was put in 10+ years ago. I was wondering if I should try to save it, and what everyone has used to try saving, perhaps an oven?

Oh Yes! Change your desiccant. Some of them do have a longer life. But I think 10 years is too long. I believe 3 to 5 years is max for most.

I agree with Suhas, replacing it would be better than trying to "save" it. You are asking for more trouble than it's worth.

The desiccant is dried as part of the overall process during the regeneration phase. Think of desiccant like a sponge. It can only hold so much water. There is a shelf-life on desiccant, but there are a few factors that can effect it. Most notably is how well the air flowing through the desiccant beds are filtered. Dust particles will clog up the pores over time and there is no cure except replacement for that.
