<p>[QUOTE="Publius2, post: 3790062, member: 105571"]I would not use the throw-away dessicant packets but if you want to try to regenerate them in the oven, you will have to leave the oven door cracked to allow the moisture to get out of the oven, and you will have to use a low heat, no more than about 100 to 125F. Additionally, most electric ovens (don't try using a gas oven) have a heating element that glows red when it is on and generates significant radiant heat while it is heating up the oven. I doubt you will be able to control the temperature these packets are exposed to using a kitchen oven with the result that they will probably make a big smoky mess.</p><p><br /></p><p>I use the small electrically-regenerated dessicant modules like Eva-Dry in my coin safes. They last about a month before I regenerate them. I open my safes about once every two or three days. Regeneration takes about 18 hours. During regeneration the outer casing of the plastic module reaches a steady-state temperature of about 110-120F-decidedly hot to the touch but you can keep your hand on it indefinitely. Been doing this about a year with no obvious issues with coins or the dessicant modules.[/QUOTE]</p><p><br /></p>
