A dry box is Dry Storage Cabinets in which 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 way to remove water vapor through the air trapped inside.
Dry boxes are employed to safely store items which would otherwise be damaged or adversely afflicted with excessive humidity, including cameras and lenses (to prevent fungal growth), and musical instruments (to avoid humidity induced swelling or shrinkage of wooden instrument parts). They are also used in the storage of surface mount electronic components prior to circuit board assembly, to avoid water absorption that could flash into steam during soldering, destroying the part.
Desiccant boxes – A simple dry box can contain simply a sealed, airtight box containing a desiccant, such as silica gel or anhydrous calcium chloride. These can easily be built at relatively low cost. However, humidity level in such boxes cannot be controlled or regulated, due to the issue of gauging the amount of desiccant needed to achieve a certain humidity level. Repeated opening of these boxes, allowing humid ambient air to get in, can saturate the desiccant, and some desiccants can have corrosive or any other harmful effects on the items in the box should they collect enough water to dissolve.
Electronic dry boxes – Electronic dry boxes contain a small Peltier cooler, which removes moisture from your air by condensing it all out. A control dial is usually provided permits an individual rough adjustment from the humidity level. More sophisticated designs link the cooler to your settable digital hygrometer, allowing very precise humidity level control.
Another kind of electronic dry box technology utilizes Dry Cabinets For PCB Storage to adsorb moisture. This moisture and humidity control technology is renewable without having to replace desiccants. Many electronic dry box manufacturers have utilize or move to this technology since there are less limitation compared to Peltier cooler which is less effective in removing moisture in colder ambient temperatures.
Need for Using a Dry Cabinet – There exists one word which will answer the question “Why do most professional photographers and photography enthusiasts require a dry cabinet for his or her camera?”. The term is “fungus”.
The fungus would be any photographer’s worst enemy. The fungus is not merely difficult to clean or remove, however it can also further damage your camera as well as your expensive camera lenses.
Moreover, the fungus often gets in between the lens as well as on your lens’ glass. Such incidents generally occur if the user stored their camera without the proper protection and subjected 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 at the same location or container.
Individuals who had encountered the problem of fungus on the camera lens had often tried to ‘force-clean’ it off. However, the above mentioned method would damage the camera lens special coating.
Photographers who do not possess 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 throughout the year.
Nonetheless, Moisture Control 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 create certain the enclosure is lower in moisture.
