GoldenRod Gunsaver Dehumidifiers:
The GoldenRod Gunsaver dehumidifiers can be installed in 2 minutes. It effectively eliminates humidity from the interior of your safe and protects against rust. The GoldenRod Gunsaver dehumidifiers circulates slightly warm dry air throughout the safe on a continual basis. This constant circulation of air is why the Goldenrod dehumidifier works so well. The 12″ size will accomodate a safe of up to 100 cubic feet. It comes with mounting brackets for easy installation. The GoldenRod dehumidifier comes with a detachable plug for easier mounting. Features a 6′ power cord and mount it horizontally at the bottom of an enclosure to work properly. UL listed. Limited lifetime warranty.
Sometimes, there is just no electrical outlet to use to power the Goldenrod, so you may want to consider either the Eva Dry E333 or the Eva Dry E500, both work without the need to have immediate access to an electrical outlet. You will however, need to recharge the Eva Dry units when they fill up with moisture.
