A temperature and humidity controlled environment is the ideal place for your coins. Hydrosorbent Silica Gel Desiccant takes the moisture right out of the air and gives you humidity control within your storage areas. Use silica gel to protect your investments in coins, currency and other valuables. We stock different weight units of gel desiccant, from 40 to 900 grams, which can be reactivated and will last a lifetime. For the best results, place these products in tightly enclosed locations, so they can drink up the humidity in that specific space. The largest units protect larger areas, such as the space in vaults and closets. Other gel units can go into lockers, safes and coin cabinets. Smaller silica gel canisters are used in drawers, boxes, and other small spaces. We carry higher grade desiccants used by government and industry to stop condensation in enclosed areas.

All of our hydrosorbent silica gel desiccants come with built-in indicators that turn from blue to pink, signaling the need for reactivation. Once the gel becomes saturated, it’s simple to reactivate for continued protection. Our silica gels feel dry even when saturated. These moisture-absorbing units maintain the environments that are a priority for committed collectors. Coins exposed to damp air show signs of oxidization. On exposed copper coins, you see carbon spots and color changes, and on silver, you’ll notice tarnish. Also, be sure to place your collection pieces in the right coin holders before storing, including coin caopsules or frames. Silica gel is non-toxic and safe, with no vapors. It fights off rust, corrosion, tarnish, oxidation, toning, and spotting. It guards against mildew and mold. Stop moisture issues before they start! Dry the air where you store collectables.

INSTRUCTIONS FOR USE

The more tightly enclosed, the more vapor-proof you can make the storage area being protected, the better. Otherwise, your silica gel will "drink up" moisture from all outdoors, becoming saturated and requiring reactivation so frequently as to be inconvenient. It's worth it to do your best to make the protected area as vapor-proof as possible. Remove the protective pouch in which your Hydrosorbent unit is packaged. Position your Hydrosorbent unit on an exposed surface anywhere within the enclosed area to be protected. Examine the indicator from time to time to see if reactivation is required.

INSTRUCTIONS FOR REACTIVATION

When you first use silica gel in the area to be protected, it may become saturated rather quickly as it "drinks up" residual moisture. Once the residual dampness is removed, you can maintain a dry condition with less frequent need to reactivate the silica gel. Reactivation times below are minimums. Sometimes, when the silica gel becomes overly saturated, it's good practice to extend the reactivation period. However, do not vary from the recommended temperatures.

When the blue silica gel beneath the inspection window turns pink, reactivate as follows: Place the unit in a vented 300 degree F oven for at least 3 hours (or until the silica gel turns blue again).
