Dehumidifier


#1

Hi Folks,

I have been fruitlessly searching the archives for a post, maybe
from a couple of months ago, that described a dehumidifier that could
be “renewed” in a microwave and that really worked well. I have also
searched Google and found an “egg” made by a company named Drytech
(sounds familiar) that seems not to be available in the US. Would the
person who posted about this please either repost or contact me off
list? Is this indeed the product and do you know of a US source?
Thank you!

I will not be able to read 33 Orchid Digests. I guess I’ll never
know what’s been happening…

a dehumidifier that could be "renewed" in a microwave 

Not sure if it is the “microwave” part that you’re interested in,
but many granular dehumidifying products can be dried out in a
regular oven and re-used. Silica gel, for instance. Sold under many
brand names and in many types of containers.

I think what you are referring to is silica gel also known as
desiccant gel. Try a google and you will find many suppliers.

Here is an example http://www.brent-krueger.com/silica.html

(not a client or anything else, just pulled it out of a google.

The advantage of the indicator types is that you know at a glance if
it needs to be renewed or not. Generally speaking it is an idea to
’cook’ new silica gel to drive out any moisture it has absorbed while
being shipped or stored.

You can buy desiccant packets at home supply/hardware stores, and
renew it by drying it out in the oven. Not sure if that’s what you
mean.

If you go to a laboratory supply company and look for Drierite
you’ll have it. W.A. Hammond Drierite in Xenia, Ohio was (maybe is)
the original manufacturer. It has a color indicator in it so that
when exhausted it changes and when heated in oven or kiln (could be
microwave) it changes back. Very cool

lisa, could you be thinking of the “rust preventer” from micro-mark?
it is a tin of silica gel that is heated in a regular oven. it takes
3 hours at 300 degrees f. the item number is 14161 and is on page 83
of their most recent catalog. they happen to be on sale for $7.25
each at the moment.

with silica gel beads, you can microwave them, as long as they aren’t
in any metal packaging. if they are very “wet” some will break from
steam being released. I’ve had to do this several times where I work,
when our air dryer (yes, I know it sounds sort of weird) needed
reconditioning quickly. The air dryer is on one of the components in
a cold vapor atomic absorption spectrophotometer we used to use.
just have a better one now.

Ah well. Yes, it is. If I had been clearer, I could have saved the
time of those who responded. I already found the silica types that
come in metal cases. Drierite looks interesting, but it needs to be
dried in a thin layer at a specific temperature (or, again, in a
metal case) and I don’t feel up to messing with a lot of loose stuff,
since this is something I will have to do frequently. The plastic
Drytech “egg” that is made in Taiwan still looks like what I need,
but I have not found a US distributor. Maybe there isn’t one.

Thanks.
