Instruction Manual


The Ruggard Electronic Dry Cabinet protects your lenses, photographic and optical equipment, mobile electronics, and other valuable accessories from excessive moisture. Using the cabinet’s fast-acting TE Cooling Wafer, you can regulate the interior’s relative humidity to help prevent fungus and corrosion from damaging your gear. The cabinet offers silent operation with no fan or compressor, and the unit is dripless, so there’s no need for a water tray. The glass door and rubber seal provide extra protection against dust or airborne debris, keeping your gear working great for years.
