WDH-50B for professional construction drying
In new buildings, renovations, and refurbishments, excess building moisture must be removed from the indoor air as efficiently as possible. The WDH-50B construction dryer supports the drying of building materials and reduces the relative humidity in interior spaces.
Especially with screed, plaster, and other damp construction materials, controlled dehumidification can help to shorten drying times. The WDH-50B can be operated over long periods, making it particularly suitable for professional construction site use.
Ideal for new buildings and renovations:
The WDH-50B is suitable for technical construction drying of indoor spaces, supporting the drying of screed, and reducing high levels of construction moisture after renovation work.
WDH-50B for water damage
After a pipe burst, flooding, or other water damage, the existing moisture must be reduced as quickly as possible. A high-performance construction dryer for water damage extracts moisture from the room air, thereby supporting the drying of affected areas.
The WDH-50B is particularly suitable for professional use in water damage restoration due to its robust construction and high dehumidification capacity. Thanks to the option for continuous operation, the device can also work unsupervised for longer periods, provided local conditions allow.

- High dehumidification capacity up to 42 liters per day
- Robust housing for professional use
- Automatic defrosting for reliable operation
- Auto-restart after power failure
- Direct condensate drainage possible
- Integrated electricity meter
Construction dryer for basements and commercial spaces
The WDH-50B can be used for more than just construction sites. The unit is also suitable for the dehumidification of basements, commercial spaces, storage rooms, and other larger interior areas.
In conditions of permanently high humidity, a professional dehumidifier can help reduce ambient moisture, thereby limiting condensation and humidity-related problems. For particularly large or highly moisture-prone rooms, the WDH-50B offers significantly higher performance than many smaller household dehumidifiers.
No humidistat – optimized for continuous operation
The WDH-50B deliberately does not have an electronic humidistat. Instead, the device was developed for the simplest and most continuous operation possible.
This is particularly advantageous in construction drying and water damage restoration, when the device is intended to dehumidify continuously over long periods. For applications where automatic regulation to a specific relative humidity is desired, a dehumidifier with an integrated humidistat might be the better choice.
Automatic defrosting and auto-restart
The automatic defrost function supports reliable operation of the WDH-50B construction dryer even at lower room temperatures. This is especially important for basement and construction site applications.
After a power failure, the device can automatically resume operation thanks to the auto-restart function. This makes the WDH-50B also suitable for long-term dehumidification projects.
Measuring and documenting power consumption
The WDH-50B is equipped with an MID-compliant electricity meter. This allows for traceable recording of the device's energy consumption.
This can be particularly practical for renting out construction dryers or when billing for drying costs after a water damage incident.

Who is the WDH-50B suitable for?
The WDH-50B construction dryer is particularly suitable for craftsmen, construction companies, renovation firms, water damage restoration specialists, property managers, and rental companies of construction drying equipment.
Particularly suitable for:
professional construction drying, water damage restoration, new construction, renovation, basement dehumidification, commercial spaces, and regular use on construction sites.
For smaller living spaces and automatic humidity regulation, a more compact dehumidifier with a humidistat might be more sensible. For very large construction projects or extremely high moisture loads, multiple construction dryers or higher-performance devices may be required.
Tips for effective construction drying
- Keep windows and doors closed as much as possible during dehumidification.
- Set up the construction dryer with sufficient distance from walls and other obstacles.
- Ensure good air circulation in the room for even drying.
- Use the direct condensate drain for longer drying processes.
- Regularly check and clean the air filter.
- Regularly monitor the room humidity and drying progress during construction drying.
- In case of major water damage, additionally have a professional damage analysis performed.
