There is a general point that all art enthusiasts photographer must note, that is whether they are owned or camera lenses of any brand with great value, must be interested small preserving jobs for them and most importantly: mildew. According to research by scientists, mildew and bacteria grow rapidly at temperatures between 18 - 30 ° C with 60% humidity and moisture that can preserve and camera lenses range from 45 % - 55%. Vietnam under the tropical monsoon climate with high humidity can reach 80%, so, this is the ideal environment for bacteria and fungi to multiply and grow. Moisture-proof cabinet is a perfect solution and ideal for any camera if players do not want to look at his brainchild gnawing moldy and destroyed.

Moisture-proof cabinet is a sealed cabinet, often made of tone, powder coated. The door is usually glazed and could face additional protection locks, door edges with rubber rings to increase tightness when closed cabinets. Inside the department desiccant cabinets, operation status light, humidity meter (hygrometer), temperature gauges (depending on type) and parameter knob. Also moisture-proof cabinets used the trays (in drag) for storage. Due to the use of electricity to operate the moisture-proof cabinets should normally fixed to a location.

Depending on the design capacity (in liters) that the cabinet will be smaller as well as larger storage capacity more or less. To determine the volume of cabinets against warm quickly to buy can do the following: (*)

- Define the size of cabinets designed to hold all the equipment needed preservation.

- Based on the dimensions identified above calculated required volume (= Length x Width x Height).

- Selection of the cabinet can be equal to or greater than the area close to the calculated number. But still need to check whether the selected cabinets are suitable to accommodate the devices do not need preservatives.

About moisture resistant design cabinets have two types as follows:

- Type moisture meter with a needle type, the control knob inside, to adjust the system need to open the cabinet, this is an inconvenient but can prevent unwanted manipulation of children .

- Type LCD clock display and the control buttons are located outside, adjust the system does not need to open the cabinet quite convenient, however if you have young children are susceptible to the naughty children.

On the operating mechanism cabinet moisture also be divided into two categories:

- Type desiccant by IC: Operating under water-cooling mechanism without air compression process and does not use the blower. Using semiconductor technology environment creates moist air is sucked. Inside moist air is condensed by a material rod cooling function, forming the mist is sucked out by small and dehumidifying unit of radiation Block including bars and thermoelectric elements vaporization outside . When the humidity in the cabinet that will maintain the achieved extent necessary to preserve the product design. This type has the advantage of compact size, better humidity control, low power consumption and quieter operation. The downside is the cost, if power is lost easily cause water condensation phenomena.

- By silica gel desiccant type: When active, dehumidifying unit (containing silica gel) desiccant task in the cabinet, this time through the external valve is closed, the valve to connect within the cabinet is opened. After no moisture, valves connect within closed cabinets, communication with external valve opens cabinets, parts desiccant is dried (by the coil temperature), moisture from the desiccant parts will be ejected out. When moist air in parts desiccant is dried it will return to the original work. This type has the advantage of low cost, fast moisture absorption. The drawback is difficult to control humidity and greater power consumption IC type used.

Some common types of moisture-proof cabinets

To purchase a moisture-proof cabinets like that you need to identify your needs and your financial capabilities, in order to avoid buying the cabinet does not meet the requirements or excessive excessive in relation to actual needs.

- The number of storage devices needed: to calculate but can be computed for all these devices, refer to fast volumetric formula above moisture-proof cabinets (*).

- The number of devices is expected to buy more (yes or no): Based on the number of devices can be added more or less that you would choose a larger area can be calculated more or less original.

- Financial capacity: According to the experience of using the moisture-proof cabinets using IC quality and cost effective but also more expensive than using silica gel moisture-proof cabinets.

Currently on the market common moisture-proof cabinet brands like: Wonderful, Darlington, Eureka, Dry-Cabi ... Some models have specifications and prices refer to the table below

Notes on installation and operation

Placement cabinet should choose a dry, low humidity and little changes will help increase the life of the cabinet. Avoid cabinet near other heat sources (refrigerator, stove...) The air flow moves directly (air conditioning ...) or near water (lake, aquarium ...), part after the cabinet to the wall at least 20 - 30 cm.

When buying new cabinets need for idling for at least 6 hours at a high level (a number of other possible cabinet - should read the manufacturer's instructions).

Should adjust the humidity in the range of 45% - 55% (humidity appropriate) as if to higher moisture prone to mold lenses, if so, it will lower energy costs unnecessarily and if left too low <30% can affect the rubber washer or glue inside the lens, the camera.

Limited to the maximum open cabinets. When opened the cabinet to take a quick step into the shower and then close immediately. Especially not forget to close the cabinet.

These materials are not necessary, avoid put in cabinets, for example, the camera strap is the most hygroscopic components, they should cast out for not necessarily in the closet to avoid power and reduced life expectancy cabinet

If you do not open the cabinet, the machine regularly often in sleep mode rather than active, otherwise it may be open cabinets or having problems. When closed cabinet, after a while the moisture is sucked out all that set, then it's no natural reason to run. In this case, check the tightness of the cabinet or contact the place of purchase for warranty service.

For moisture-proof cabinets using metal hygrometer clock, after about 6 months to 1 year, the operation of the clock can be misleading indicators lead to incorrect humidity. Then take a calibrated (calibrate) to watch the show more accurately measured parameters. Can contact the place of purchase (if the machine is under warranty) or manually remove the clock out (if the machine out of warranty), then to where purchased closet, thanks to store calibration accuracy (by comparison with the clock in the new cabinet). The mechanical watches are turning knobs, or screws to refine the exact parameters

Hygroscopic parts of the moisture-resistant boxes sold as such, although all but two forms of silica gel used. Another type of particle to replace the moisture-saturated water (color transfer) or manually brought drying. The other type is a bit more modern was built by the thermal drying, drying box only bring out the power plug after a period of time (desiccant transforming the original color) can be used to put in the box.
