What is the dehumidification principle of SUPER DRY/ AUTO DRY?

  1. The drying agent absorbs the moisture inside the cabinet.
  2. The absorption process will stop once the setting humidity level is achieved.
  3. The absorbed moisture will be heated and discharged as vapor.

Are SUPER DRY and AUTO DRY "CE" approved?

Except MT series and SDC series, all SUPER DRY and AUTO DRY series are CE approved.

Is there any life cycle in the drying agent? If yes, is it possible to exchange it?

The way how the drying agent absorbs and discharges the moisture inside the cabinet is a physical phenomenon, so theoretically there is not any life cycle in the drying agent. The dryer units we usually repair are those which have almost been used over 15 years, and we mainly repair the electric parts, rather than the drying agent.

Is it alright to put something with mold inside SUPER DRY/ AUTO DRY?

We do not recommend to put anything with mold into dry cabinet. It is because the mold will not perish without a professional maintenance, also the mold item will also affect other stored items inside the dry box.

Are there anythings that are not recommended to store in SUPER DRY/ AUTO DRY?

Yes, please do not put flammable or volatile materials such as benzene, LP gas, or alcohl etc in the dry box.

What should I do if humidity drops too low?

Put something saturated with moisture inside AUTO DRY, then the humidity will rise gradually.

Does the red LED mean AUTO DRY is under the dehumidification process?

The red LED means the setting humidity is being adjusted (the absorbed moisture is being discharged as vapor in 30 mins).

How does AUTO DRY control humidity level?

It is controlled by a sensor inside the drying unit.
