A dry box is Low Humidity Control Cabinets where the interior is kept at a low degree of humidity. It may be as easy 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 affected by excessive humidity, including cameras and lenses (to prevent fungal growth), and musical instruments (to prevent humidity induced swelling or shrinkage of wooden instrument parts). Also, they are utilized in the storage of surface mount electronic components just before circuit board assembly, to stop water absorption that could flash into steam during soldering, destroying the part.
Desiccant boxes – A basic dry box can include nothing but a sealed, airtight box containing a desiccant, such as silica gel or anhydrous calcium chloride. These can be easily built at relatively low cost. However, the humidity level in such boxes should not be controlled or regulated, owing to the problem of gauging the quantity of desiccant necessary to gain a certain humidity level. Repeated opening of the boxes, allowing humid ambient air to get in, can saturate the desiccant, plus some 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 include a small Peltier cooler, which removes moisture through the air by condensing it. A control dial is usually provided permits an individual rough adjustment in the humidity level. More sophisticated designs link the cooler to some settable digital hygrometer, allowing very precise humidity level control.
Another kind of electronic dry box technology utilizes Dry Storage Cabinets For Optics to adsorb moisture. This moisture and humidity control technology is renewable without needing to replace desiccants. Many electronic dry box manufacturers have utilize or change to this technology because there are less limitation than the Peltier cooler that is less efficient in removing moisture in colder ambient temperatures.
Importance of Employing a Dry Cabinet – There is certainly one word which will answer the question “Why do most professional photographers and photography enthusiasts need to have a dry cabinet for their camera?”. The word is “fungus”.
The fungus will be any photographer’s worst enemy. The fungus is not only challenging to clean or remove, but it can also further damage the digital camera and your expensive camera lenses.
Moreover, the fungus often gets in the middle the lens and on your lens’ glass. Such incidents generally occur once the user stored their camera without the right 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 placed at the same location or container.
People who had encountered the problem of fungus on the camera lens had often attempted to ‘force-clean’ it off. However, the above mentioned 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 throughout the year.
Nonetheless, Moisture Control Cabinets are definitely the absolute essentials for just about 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.
