Those "Keep-Dri" bags WILL freeze. When they do freeze, they burst at a seam spilling a gelatinous mess which is very difficult to remove. If you choose to use this type of crystal dessicant, you'd be wise to have a large bucket under it to contain the mess should the temps dip below freezing.
The dessicant dehumidifier does not use any type of crystals. Like the industrial-strength dessicant machines (see ztirffritz's post), it uses a multi-faceted ceramic wheel with a dessicating surface. The wheel soaks up water from the atmosphere, and then passes past a heating element that removes it.
These are said to be good to 32ยบ F, and I assume will work below that, but these home units then run the risk of the output water freezing. The larger ones I gather remove the water with a blast of hot air exhausted outdoors.
The new Ivation unit interests me, but it's so new it's not even on Ivation's website yet.
