I was wondering just to get a general idea for the guys who store their coins in enclosed spaces such as home anchored safes, safe deposit boxs, security companies, etc..And for the ones who use a moisture absorbing substance if they use the regulaur Silica gel, or a Eva dry 500 de-humidifier. The difference as far as i can tell is: The eva dry 500 de-gumidifier absorbs moisture from your enclosed space and traps it in moisture absorbing beads in the plastic unit, when the beads change from blue to pink you just plug it into the wall and for 6-8 hours it takes to empty the moisture, you use a outlet instead of the oven. Regular Silica Gel whether in a metal holder, or raw house casing you normally recharge in the oven for 2-4 hours or until the beads resume the normal color. Most come in 1 gram packets up to 5 pounds bags depending on how much you need, althoughy 40-100 grams would be ok for most safes. So as a quick review, the eva dry is basically Silica Gel but it recharges in a outlet via wall or any other outlet, the cons are though when re charging it gets extremely hot and its heavy with all the moisture it aborbs, making it hard to keep it plugged into the wall, so normally you must place it vertical to a power strip. Silica moisture absorbing gel can basically do what a eva dry de humidifier does but recharges in the oven, normally in less time. What would you use, or what do you guys use?
In my big SDB I have a 450 silica but smaller in the smaller boxes. Dont know of the Eva Dry and I'd like to hear from someone that does. I'm thinking for a SDB it won't help as you'd have to bring it back to the house either way.
Here are some related threads the OP might want to peruse and subscribe to with relevant advice: Home Safe to store coins "Safe Condition"
let's said we bought 60 single bag of silica gel. and we use only 40. what will happen to the other 20 bag?. how can we keep it as new or never use?.
you mean to say just seal it. how long does this silica gel end?. can we put it inside the oven too. just like the 40 gram thing. so we can throw out those being use for few months.
Just saying... some questions we see on CT could be answered better by direct inquiry to the product maker, on their web site or by the consumer actually reading and following the instructions provided with the product. I know people seek advice from experienced others but at some point the hypotheticals become a bit absurd(?) or silly in simplistic "what if" scenarios that ought to be self evident given a bit of thought prior to posts. :smile
I've got four of the small silica gel cannisters in a 1.2 cu ft safe, and they still need to be recharged every two weeks. These Houston summers are fun. Thinking of getting an eva dry as well for the closet.
