Price includes 8.1% VAT.
For many years, this WDH-520HB dehumidifier (or Akto 521) has been one of the best-selling devices in Switzerland.
As a multiple test winner, it reliably keeps cellars and hobby rooms dry and is a great help in drying laundry.
Who is the WDH-520EB dehumidifier suitable for?
The WDH-520EB dehumidifier is a compact and efficient solution for anyone who wants to reliably dehumidify small to medium-sized rooms. It is particularly suitable for use in private living areas.
Ideal for smaller rooms and apartments
The WDH-520EB is optimally suited for rooms with moderate humidity. This includes cellar areas, archives, or laundry rooms. It ensures a pleasant indoor climate and protects against moisture damage. The device helps to reduce condensation and prevents mold growth and unpleasant odors.
Support for laundry drying
The dehumidifier also provides good service when drying laundry indoors. It significantly shortens drying time and improves the indoor climate during the process.
Compact and user-friendly
Thanks to its compact design, the WDH-520EB fits even into smaller rooms. Its simple operation, automatic shut-off, and reliable dehumidification performance make it a practical everyday helper.
Suitable for daily use
The dehumidifier is designed for regular use and is particularly suitable for living spaces where constant humidity is important.
Not suitable for
The device is less suitable for very large rooms or construction sites. In such cases, more powerful dehumidifiers are required.
Functions
Weighing only 13 kg, with four castors and a practical carrying handle, the device is extremely mobile. Thanks to the new digital control, you can intuitively set the target humidity, ventilation level and timer by pressing a button.
Operation is fully automatic: the device only switches on when the air is too humid, and pauses completely (including the fan) as soon as the target value is reached. This effectively saves electricity.
Environmentally friendly & powerful
Thanks to state-of-the-art technology and the natural refrigerant R290, you protect the environment. Despite its compact design, it reliably dehumidifies rooms up to 50 m² (125 m³) even at cool 10 °C.
