Dehumidifiers will too Dehumidifieror just called a dehumidifier. They are used to lower the absolute humidity in a container or in a room. They are used, for example, to dry water damage and buildings that generate large quantities of water vapor (swimming pools) and to dry historic buildings, old and new buildings to prevent the formation of mold. Furthermore, the units can be combined with humidifiers and operated to achieve a constant humidity in a container or in a room. Smaller models with adsorbents can also be used in vehicles to prevent fogging inside the windows.

Criteria to consider when choosing a humidifier

In order to avoid a bad purchase and the associated additional costs and disappointments, the following criteria must be observed when selecting a dehumidifier. An important selection criterion is the dehumidification performance per day. This is stated by the manufacturers in liters. In addition, the equipment (eg heating module, blower, hygrometer), the size of the condensed water tank and the power consumption (power consumption of the dehumidifier) ​​must be taken into account when selecting the suitable electrical appliance. The desired model should also be easy to use and maintain.

Functional principle of electrical Dehumidifiers

The job of dehumidifiers is to extract excess moisture from the indoor air to minimize relative humidity. The majority of models offered works on the condensation principle. There are also devices made with granules. The air is drawn in by the device, heated and immediately cooled to effect condensation. The accumulating condensation is conducted into the tank of the device and collected. The offered devices are available with tanks with a capacity between 2.5 to 7 liters. Especially in rooms where the humidity is very high, a product with a large condensed water tank should be selected. Otherwise, the constant emptying of the condensed water tank turns out to be a nuisance. In addition, dehumidifiers automatically switch off as soon as the tank is full. In this case, the humidity increases again and the risk of mold formation increases.

For devices that are to be used in different rooms (attic, living rooms and cellars), the weight of the device should be considered sufficiently when selecting the dehumidifier. The majority of offered Dehumidifiers are equipped with rollers at the bottom and can be changed without the use of physical strength. However, if the dehumidifier needs to be carried on different floors, every kilogram more difficult to transport.

The majority of models, for example the product Aktobis Dehumidifiers , Dryer WDH-520HB (up to 25 L / T), requires no maintenance. The power consumption is not too strong. An automatic function integrated into the dehumidifier ensures that the dehumidifiers automatically switch on and off when the set parameters are undershot or exceeded. An additional, automatic safety shutdown is also part of the basic equipment of dehumidifiers. As soon as the condensed water tank is filled, it switches off the dehumidifier immediately.

Practical are products that are equipped with a connection for an external hose, with which the condensed water collected in the tank can be discharged directly. This offers the user the opportunity to use the Dehumidifiers To operate permanently, since the manual emptying of the condensate tank is eliminated. Even in the case of short-term absence, for example over the weekend, an external hose has proven itself countless times in the past.

Different versions of dehumidifiers

The supply of dehumidifiers is great. If you would like to purchase a dehumidifier, you have the choice between compact devices that are suitable for mobile use and devices that have been developed for professional use (building dryers). Building dryers have a higher performance and are used, for example, on construction sites and in warehouses. The high-performance professional dehumidifiers can also be used to eliminate water damage, for example by extinguishing water. Another advantage of powerful construction dryers, for example from the model Atika 303990 Dehumidifiers ALE 500 is that they can be used in frosty conditions. For private homes and houses, however, ecologically working room dehumidifiers are generally sufficient. Disadvantages of building dryers are the high power consumption, the risk of drying out the room air too much and that the operation of this dehumidifier, a building opening is required. In addition, building dryers generate very loud operating noise, which can be the cause of disputes with the neighbors.
