A Dry Cabinet is a storage cabinet which protect objects from problems cause by humidity.
Fungus can grow on the surfaces inside your lens, providing there is enough moisture (and a bit of dust or lens adhesive to “eat”). Over time, the fugus can etch into the surface of the glass, causing permanent damage to the lens performance. The etched spots in the lens glass alter the lens surface and characteristics, reducing performance significantly and contrast in particular. A Fungus attack which hasn’t altered the lens shape or etched into the glass, but only eaten away at the very thin outer lens anti-flare coating, is less damaging to lens performance. Once the lens coatings and surface are etched and damaged, removing the fugus won’t return the lens to original performance levels. You have to replace the damaged lens elements, which is usually so expensive it is cheaper to just junk the lens.
While fungus can be removed during a lens CLA (clean/lube/adjust), the damaged and etched lens elements may costly to replace. Not every fungus spore will be removed during even the most thorough cleaning. Even if you sterilized the lens elements (not recommended), fungus spores would still be sucked into the lens during focusing and use. Many people warn against using leather lens carrying cases or bags as a potent source of fungus infection.
But there are enough fungus spores in the air (often hundredsper cubic meter) that lenses are easily infected in general use. So since you can’t get rid of fungus spores, you simply have to make your lens an inhospitable “desert” in which fungus can’t live or grow.

Singapore and most South-East Asia region countries fallsbetween 70%RH-90%RH. Mold is not prevented as air-conditioners and dehumidifiers usually cannot reduce RH below 60%. So the real solution to prevent fungus attack is to reduce the available moisture, so the fungus cannot grow and multiply.
The AD Series and DHC Series uses T.E.Cooling regrigerated crystal which is a semiconductor crystal for absorbing the moisture of the cabinet interior air. Whenever the humidity of the cabinet is higher than the set RH% value, the Cooling regrigerated crystal will start to refrigerate and condense the moisture until the humidity of the cabinet is down to the set RH% value. Once crystal stops working, it begins to defrost as well as evaporate the moisture out of the cabinet.
In comparision with similar products, the efficient rate of our dehumidifiers is 10 times faster but the power consumption is only 1/10 of those.
