Dehumidification Principle:

  1. Totech Super Dry relies on dry units to control humidity levels, and the dry unit will be recycled every several hours to discharge the moisture absorbed through shutter to outside the cabinet. After recycling, the shutters will close and moisture inside dry cabinet will once again be absorbed by refreshed drying agent.
  2. This dehumidification cycle will continue until the set humidity value is achieved. Once the humidity level exceeds the setting level, this dehumidification cycle will start again.
