Hydrosorbent SG-450 Silica Gel Dehumidifier

Rechargeable silica gel dehumidifiers absorb moisture in enclosed areas preventing condensation and stopping rust, mildew, corrosion, and spoilage. 450 Gram Silica Gel Unit protects and is ideal for anything 5 cubic feet to 33 cubic feet of enclosed space. Ideal for safes, gun cabinets, large storage containers, and much more.

Each unit has a built-in indicator that turns from blue to pink to signal it has reached its maximum moisture saturation level. Once that level has been reached, the unit can easily be recharged in any conventional oven. Just put the bag of crystals in the oven at 250 degrees F for 3 hours and you are fully recharged and ready to go again for 4-12 months. Charge times vary depending on how humid your climate is. The units can be recharged as often as needed for lifetime protection.
