Why is it important to use not only humidifiers, but also dehumidifiers?

Many of us spend a lot of time indoors without even thinking about how the microclimate affects our well-being and health in general. Often, even the purchased humidifier, which is so often talked about on television or on the Internet, is in the box or — even worse — is used in situations where dehumidifiers actually need to be installed.

The use of such devices is important both in industry and in everyday life: in addition to reducing humidity, they will also reduce the number of bacteria and microorganisms that can harm health. And the harm can be quite serious: from rhinitis, allergies and fatigue to exacerbation of hypertension, atherosclerosis, cardiovascular diseases. If you smell damp, the air feels «heavy», washed clothes take a long time to dry, and your skin feels sticky, it’s possible that the humidity is high and it’s time to look for a good dehumidifier. We will help with this.

Best of the best: TOP 4 dehumidifiers in our catalog

A series of Danish stationary condensing dehumidifiers Dantherm CPD is one of the most popular among our customers. The manufacturer presents three models of different productivity: version 40 removes up to 34 liters of moisture per day, 50th version — 78, 70th — 108 liters. This unit runs on R407C refrigerant. It is chemically and thermally stable and, due to its low toxicity, does not deplete the ozone layer.

The most economical device consumes 0.9 kW of electricity, the maximum power consumption is 1.8 kW. CPD 40 processes up to 400 m3 of air per hour, CPD 50 — 680 m3, version 90 — 900 cubic meters. Models are perfectly protected from moisture ingress (IP X4 standard), which makes them, along with all other characteristics, an excellent option for creating an optimal microclimate in swimming pools, sanatoriums, hotels, beauty salons. The device is not particularly compact: the dimensions of the SPD 40 are 77 × 101 × 32.6 cm. Among the advantages of this model:

• resistance to oxidation and corrosion due to the use of hot-dip galvanized steel and aluminum coated with an epoxy layer;
• automatic mode: due to the built-in hygrostat, the device automatically controls the power supply of the compressor, maintaining the level of humidity in the air at around 60%;
• the presence of a special sensor, which, in the event of the formation of an ice cover in the evaporation chamber, temporarily turns off the refrigerant supply for the purpose of defrosting.

With USB and BMS ports, you can connect the dehumidifier to remote monitoring systems, and the remote control allows you to adjust the operating mode at a distance of up to 100 m.

Let’s take a look at each set separately. Dantherm CDP 40, the most modest in terms of characteristics of the entire series, operates relatively quietly: only 46 dB of noise, which is below the maximum allowable level for non-residential premises. The dehumidifier is quite heavy and weighs 56.5 kg, but for a stationary model, this is quite normal. Although it is mounted on the wall with brackets, it is therefore necessary to take this point into account during the selection. The equipment costs from 250,000 rubles.

The middle version — CDP 50 — consumes 0.6 kW more electricity than the previous one. It is also much more productive — the daily moisture removal rate is 78 liters. At the same time, the noise level is only 1 decibel higher. The weight of the device with the same dimensions is 65 kilograms. It works, like other configurations, from an electrical network with a voltage of 220 V. The price of such a dehumidifier will be a little more than 292 thousand rubles.

Well, the “maximum speed” is CDP 70. It differs in the operating volume of 50 dB, which is almost the maximum allowable for non-residential premises, this modification is a great option for large pools. The weight of the package is 75.5 kg. It will cost you more than 400 thousand rubles.

How a condenser dryer works

Another popular model is the Finnish household dehumidifier DanVex DEH-1000p. It is presented in one, but rather powerful configuration: with air exchange up to 450 m3 / h per day, it removes up to 80 liters of moisture. This model also dries the air, condensing it and collecting it in a 7-liter tank. It is mobile and stands well on the floor, and its dimensions of 63x48x30 cm and weight of 25 kg allow you to place the dehumidifier on a shelf or table. The manufacturer positions it as a device for home, apartment and laboratory, which is fully justified by the characteristics. And the price is appropriate — 67 thousand rubles. The model also has other important features:

• modern design of the case, made of durable plastic, there is an LCD display, temperature sensor, hygrostat;
• due to the automatic mode of operation, the device will independently maintain a predetermined humidity value;
• moisture can not only be collected in containers, but also drained through the drainage hose into the sewer.

If the water container overflows, the device will automatically turn off, so you don’t have to worry about water spilling and damaging it.

The next, already two adsorbing models are radically different both in terms of characteristics and price. Most of these devices are designed for industrial use, but there are also household models. Let’s look at each type.

Working principle of adsorption dryer

Household Trotec TTK, manufactured in Germany, is presented in two variations: 96E and 127E. It works like this: after setting the desired humidity indicator on the hygrostat, taking into account the ambient temperature, the freon cools the incoming air masses in order to obtain condensate.

You can adjust the power consumption of the device by selecting normal ventilation or air drying mode. This portable desiccant dehumidifier is used for home, basement, storage of papers, books and other items made of materials that are not resistant to moisture. Like the Danish model, Trotek independently defrosts a layer of ice if it appears.

The common features of both sets are as follows:

• the presence of an indicator of operation and filling of the drain tank, a timer;
• normal operation at external temperature from 5 to 30 °C;
• can be placed anywhere due to the portable design.

TTK 96E removes up to 30 liters of water at maximum settings, passing up to 210 cubic meters of air. The condensate tank is quite small — only 3 liters. The device operates at a maximum volume of 51 dB, consuming only 0.46 kW of electricity. The package weighs only 15.3 kg with dimensions of 26 × 38.6 × 50 cm, and its cost is more than affordable — only 25 thousand rubles.

The 127E version with a daily dehumidification rate of 50 liters and an air exchange of 345 m3 / h has a container with a capacity of twice the size of 6 liters. It consumes a little more — 0.78 kW, but makes noise at the same level. Weight, with a slight difference in dimensions, which are 616 × 392 × 282 mm, is 20 kg, so the floor of the apartment, and the table, and a well-fixed cabinet shelf will be an excellent place for this dehumidifier. Such a powerful model will cost only 5 thousand more — it can be purchased for 30 thousand rubles.

Industrial dehumidifiers from the Aerial ASE series are also made in Germany and are available in two configurations with a capacity of 19 and 26 liters per day, respectively: ASE 200 and ASE 300. They do not use Freon for operation, removing excess water using the ECODRY G-3 rotor . The top-mounted handle makes moving the device more convenient. But this is not all the features of the model. Among them:

• robust housing made of powder-coated stainless steel sheet;
• the temperature range at which the device works without failures is quite wide, and is -10 .. +35 ° C;
• an energy-efficient centrifugal fan processes and regenerates the air, while sensors make it possible to track running hours and energy consumption.

The ASE 200 package processes up to 210 m3 of air per hour, consumes less than 0.7 kW and operates relatively quietly — at 48 dB at maximum settings. Despite the industrial purpose, it is quite compact and weighs only 14 kg with dimensions of 285 × 290 × 390 mm. The model costs from 150 thousand rubles.

ASE 300, in turn, is quite loud: the level at maximum power will reach 57 dB. The air exchange of the complete set is 300 m3 / h, and it consumes up to 1.04 kW of electricity. This model is also more massive: its dimensions are 37 × 33.5 × 43 cm, and its weight is 18 kg. You can buy an industrial air dryer of this configuration from us for 173,300 rubles.
