Safe desiccant
« on: June 18, 2018, 09:22:04 PM »
For you guys that use desiccant in your safe, how often do you have to recharge / reheat them?
Seems like mine only last about a week each before I have to reheat them.
They are the EVA Dry E-500:


Is that pretty typical?

When it is new, they last about 2 weeks. After a while, its down to 1. Mine is 4 years old, and I need a new one.... Mine lasts maybe 4 days now.

I have the Remington one - with a 5 year warranty. It was a free replacement because the last one didn't last the 5 years. This one has lasted longer than my last one.

But, it probably should be replaced every 3-4 years

Thanks Ship, didn't even think they might expire with time.

Yes, they don't last as long over time.

I am on my 3rd or 4th one total

So might the $30 rod heaters work better / longer?

They would, if you have a place to plug it in at by your safe, and you have one of those holes in  the safe to run the wire through.

I used to have my safe in a closet, and I had no power plug.

I am fine with what I am doing, though. I will probably just buy another one soon

I put two strings of neon lights in my big safe that I leave on all the time.

I was told as long as the inside of the safe is warmer than the outside, it wont draw moisture.

I also didnt know these desiccant things expired. I only need to plug mine in about twice a year. Might have to take a look at that.

I have not had any rust issues yet.

But I also wipe a coat of carbide base grease on all my old guns and any I think may be stored for long term. . And that  stuff just dont wipe off.

I use two EVA Dry E-500 and take one out to plugin every few weeks to keep them rotated. Never had any problems and they dry out well with an overnight plugged in.
Bought my first in 2012 and second in 2013 and working perfectly.
If you are having to dry them out that often, your safe is either not close to air tight, or you open it a lot.
Mine is typically opened twice a day on average, and is a 25 gun Liberty Timber Ridge.

To All,

There's a company that is sometimes on ebay that sells what looks like a tallboy beer can with numerous drilled holes. - NOT expensive & every 45 days you have to dry it in a 400 degree oven for 2 hours. - The vendor says that the "beer can" is guaranteed for the life of the original buyer.

I think that I remember that the "beer can" is about 20.ooUSD.

yours, satx

I have a big canister type I picked up at Tractor Supply and a couple of the EvaDrys.   I recharge every 2-3 months.

You guys are pretty fancy.

I'm a low-tech guy.

I have had good luck with this stuff:


I dump it and refill the absorbent about once every 2 months or so.
It works and it's cheap.

Well, the Remington ones DO have a lifetime. And, whenever I get a new one, then it lasts a lot longer for the first year or two.

Over time, thru repeated use, those little drying beads inside do wear out. I usually only open my safe 2x a day. I've had the safe long enough, and gone thru 3 or 4 of those little Remington dehumidifiers (pretty much the same as what was shown here, just a different shape) that I know about how long they last.

I do leave them plugged in over night, but they still last less and less as time goes by. At least the ones I have owned do...

The canister from TS works fine.
Last 4-6 mo before needs to be serviced and returned.

i don't really have a safe per se, more of a secure sturdy locker.
i use those desiccants from dollar tree that fill up with water they
draw in the bottom of the reservoir, then you toss it and put
another one inside of your spot your wish to keep humidity free

I guess it depends how air tight your locker/ safe is. Ive used metal desiccant cans in zip lock crates before and they're good for about 1-2 months before needing a recharge. 400F for 90 min if I remember correctly.

This thread got me to take the boxes out of the big safe and plug them in.

But I forgot the one over night.  :bangheadonwall:
Next day, I walked past and herad it hissing. that SOB was so hot you couldnt hang onto it.  :afraid4:
So i grabbed a rag to unplug it. It was hissing and sizzling , :afraid4: , but the window was nice and blue.  :th_thicon_funny:

I wasnt so sure it woulndnt catch fire.
I put it in the fireplace for safe keeping until it cooled off.  :th_thicon_lol:

Bet I DONT do that stunt again.  :P
