Dehumidifier for construction

DT850 AnwendungWhether small rooms in new buildings or large construction sites and renovation work - dehumidifiers are now an integral part of the drying of floors and walls. HEYLO offers the right building dryer for every room size and condition, with which you can remove liquid from the room air and thus prevent mold in the masonry. The decisive factor here is the dehumidification performance of the building dehumidifier, which differs between the HEYLO models and is specially adapted to your needs.

At HEYLO you will find condensation dryers for:

- The professional dehumidification of the air in living rooms and basements

- The drying of walls and floors after the application of plaster or screed in new buildings and renovation projects


Types of electric dehumidifiers

There are two types of dehumidifiers for electric air dehumidifiers:

  • Adsorption dehumidifier
  • Condensation dehumidifier

In an adsorption dehumidifier, the water is removed from the moist air by means of a hygroscopic gel. The advantage of these devices is that, unlike condensation dryers, they can also be used at low temperatures without any problems.

On the other hand, condensation dehumidifiers can only be used without heating at temperatures of at least 0.5 ° C. However, building dryers with compressors have a higher dehumidification performance, which is why they are used especially in the event of water damage and in larger rooms.

HEYLO dehumidifiers for the construction site

Long drying times for plastering or screed work cause delays on the construction site. Because if the next steps are taken before drying, mold or further damage to the masonry can occur. In order to accelerate the drying process, you should therefore not do without an electrical construction dryer. This removes the moisture from the room air and transports the remaining water into a container, which is later emptied.

For small rooms in new buildings or for renovation work, a compact dehumidifier is recommended, which, despite its size, efficiently removes moisture from the room. The types DT 650 / 750 / 760 are particularly suitable for dehumidifying smaller rooms.

The smallest model from HEYLO is the DT 650. With a dehumidification capacity of a maximum of 26 l / 24 h and an air capacity of 300 m³/h, it dehumidifies small rooms efficiently and reliably. The water tank holds 5 liters, which contributes to the low weight of only 22 kg. In this way, it can be quickly rolled into other rooms in order to start the next dehumidification there. With the elegant design and the plastic / metal housing that hides unsightly pipes and the compressor, the construction dryer adapts to the modern interior design of a room.

The DT 750 and DT 760 are only slightly heavier than the DT 650, but work with a maximum dehumidification capacity of 28 l / 24 h. 350 m³ of air are dehumidified per hour. With a volume of 43 dB (A) / 3 m, they are also very quiet and can also be used in the early morning or evening hours.

HEYLO dehumidifiers for commercial use

Large and powerful building dryers are ideal for dehumidifying entire buildings and larger rooms during renovation work. Depending on the model, these have an energy meter and an integrated operating hours meter for control purposes.

The DT 860 reliably dehumidifies with a maximum dehumidification performance of 43 l / 24 h. It processes 500 m³ of air in one hour. The large 8 liter water container ensures that it rarely needs to be emptied. In this way, the dehumidifier can be used for many hours. In contrast to the smaller models, the DT 860 can also be used at temperatures of 5 ° C, which is why this model is well suited as a construction dryer for commercial use.

The DT 960 is a real heavyweight with a weight of 49 kg, but works with a maximum dehumidification capacity of 58 l / 24 h - about twice as much as the DT 750 and the DT 760. The air capacity of this model is 650 m³/h. Thanks to the practical handle and robust castors, the condensation dryer can be used specifically in buildings and placed in different rooms.

Use a dehumidifier in the cell

DT650 Anwendung


Especially in the summer months, warm air penetrates cold cellars and the water vapor condenses on the cellar walls. As a result, the walls are damp and the humidity in the basement increases. Wet laundry that needs to be dried also increases the humidity. Damp basement walls, however, encourage the formation of mold, which not only harbors health risks, but also structural risks: the masonry becomes unstable as a result of the mold infestation.

To combat damp basement walls and thus mold, it is worth using a professional electric dehumidifier. The building dryer absorbs the water vapor from the room air and collects it in a container. With a maximum volume of 51 dB (A) / 3 m, the drying devices from HEYLO can hardly be heard when used in the basement on the upper floors. Some models can also be used in acute emergencies such as water damage in the basement.


What are dehumidifiers and how do they work?

Especially in new buildings or during renovation work in the living room and basement area, moisture quickly develops through the use of damp building materials or the drying of laundry. So that the water does not penetrate the walls and form mold there, which in the worst case destroys the masonry, the humidity should be 40 to 60 percent. In order to achieve this value, moisture must be extracted from the room air. A dehumidifier ensures a reduction in humidity either through adsorption or condensation and thus prevents the formation of mold.

In a condensation dryer, a fan draws in the air and then cools it below the dew point. The water vapor condenses on the surface of the evaporator and drains into a water container. The dehumidified air returns to the room, where it absorbs moisture again. The process of condensation takes place until the desired value is reached.

How long does a dehumidifier have to run?

The duration of use of a dehumidifier depends on many factors. In order to be able to determine the duration, the following questions must be asked:

  • How high is the humidity in the room?
  • How big is the room to be dehumidified?
  • What is the room temperature?
  • How powerful is the construction dryer?

All of these factors have a very strong influence on the service life of a dehumidifier. It is therefore difficult to estimate how long it will take to completely dehumidify a building or a room. Depending on the size and performance of the drying device, this process can take several hours to a few days. Even with major water damage, the running time increases. It is important that you choose a construction dryer that has a high dehumidification capacity. For small rooms, a compact device with a lower air output is sufficient. When dehumidifying larger rooms or buildings, you should use a model with a dehumidification capacity of at least 26 l / 24 h.
