A dry box is Low Humidity Control Cabinets where the interior is kept at a low level of humidity. It may be as basic as an airtight and watertight enclosure, or it may use active methods to remove water vapor from the air trapped inside.
Dry boxes are employed to safely store items that would otherwise be damaged or adversely afflicted with excessive humidity, including cameras and lenses (to avoid fungal growth), and musical instruments (to stop humidity induced swelling or shrinkage of wooden instrument parts). They are also used in the storage of surface mount electronic components before circuit board assembly, to prevent water absorption which could flash into steam during soldering, destroying the part.
Desiccant boxes – An easy dry box can consist of simply a sealed, airtight box containing a desiccant, including silica gel or anhydrous calcium chloride. These can easily be built at relatively inexpensive. However, humidity level in such boxes should not be controlled or regulated, owing to the issue of gauging the amount of desiccant required to achieve a certain humidity level. Repeated opening of these boxes, allowing humid ambient air to enter, can saturate the desiccant, and a few desiccants can have corrosive or other harmful effects on the items in the box when they collect enough water to dissolve.
Electronic dry boxes – Electronic dry boxes contain a small Peltier cooler, which removes moisture through the air by condensing it. A control dial is normally provided that permits an individual rough adjustment of the humidity level. More sophisticated designs link the cooler to your settable digital hygrometer, allowing very precise humidity level control.
Another type of electronic dry box technology utilizes Dry Storage Cabinets For Optics to adsorb moisture. This moisture and humidity control technology is renewable without having to replace desiccants. Many electronic dry box manufacturers have utilize or switch to this technology because there are less limitation compared to the Peltier cooler which is less effective in removing moisture in colder ambient temperatures.
Need for Using a Dry Cabinet – There is one word which would answer the question “Why do most professional photographers and photography enthusiasts require a dry cabinet for their camera?”. The phrase is “fungus”.
The fungus will be any photographer’s worst enemy. The fungus is not only hard to clean or remove, however it can also further damage the camera along with your expensive camera lenses.
Moreover, the fungus often gets in the middle the lens and also on your lens’ glass. Such incidents generally occur if the user stored their camera without the proper protection and exposed to the humid environments where fungus thrives. Once fungus grows, it is going to spread rapidly and may infect other equipment that is certainly placed in the same location or container.
Those who had encountered the problem of fungus on their own camera lens had often tried to ‘force-clean’ it off. However, the aforementioned method would damage your camera lens special coating.
Photographers who do not have dry cabinets often place their cameras and photography tools in cupboards and drawers. These dark and humid spaces are areas which fungus thrive. Furthermore, photographers who often faced jmmhra problems generally live in countries where tropical climate and humidity exist all year round.
Nonetheless, Dehumidifying Dry Cabinets would be the absolute essentials for virtually any photographer or photography enthusiasts to equip themselves with. Ensuring your pieces of equipment stored are dust-proof, waterproof with humidity regulated to help make certain that the enclosure is lower in moisture.
