FAQ – How to choose an industrial air dehumidifier?
Excess humidity in production workshops and storage areas causes many problems. Air dehumidifiers are designed to meet the different needs of professional users in the construction and industry sector as well as on work sites. Air dryers and dehumidifiers regulate air humidity. This is why various criteria must be taken into account when choosing the right equipment.
Which air dehumidifier for which surface area?
The first factors to consider are the amount of water to be extracted and the volume of the room to be treated (m3). The amount of water to be extracted can be expressed in litres per day or in grams of water per kilogram of dry air. The atmosphere to be maintained can also be expressed as a percentage of relative humidity (RH). The higher the values, the greater the dehumidification capacity and performance of the equipment. It is essential that the dehumidification capacity is matched to the volume and surface area of the room or industrial workshop for which it is intended.
DESSiCA equipment is suitable for small and large areas, providing 160m³ to 13,000m³/h of dry air.
Noise level
The noise level increases exponentially with the power of the unit. The average noise level of industrial air dehumidifiers is 63 dB(A), which is equivalent to the noise inside a moving car.
Water drainage system
Industrial air dryers operate on the principle of adsorption and feature a silica gel-based desiccant wheel.

The humid air is expelled outside the building in the form of water vapour. No monitoring is required on the device, as it operates in full autonomy. These systems can be used at very low humidity levels (down to a dew point of -60°C). Air dryers are highly efficient in all industrial and professional environments and consume little energy compared to devices of the same size.
In contrast, with industrial condensation dehumidifiers, the water collected by the device is stored in a tank, which must be emptied daily. Industrial dehumidifiers operate using refrigerant gas and can be either fixed or mobile. The nominal dehumidification capacity ranges from 44 litres per 24 hours to 96 litres per 24 hours (at inlet conditions of 30°C and 80% relative humidity). For unheated rooms, the operating range is between +7 and 35°C. Some models switch off automatically when the tank is full. To avoid having to empty the condensate drain tank, some devices are equipped with a water drainage system. Dehumidifiers can also be equipped with a lift pump that directs the collected water to a drain located higher than the appliance.
Control and operating mode
Industrial dehumidifiers can be fitted with a hygrostat, enabling precise humidity control on selected models. For fixed installations, a remote start option is available, allowing the units to start and stop automatically according to the programmed settings. A meter can be installed to record the dehumidifier’s operating time.
Additional features
Industrial air dehumidifiers are equipped with dust filters, some of which are washable with water. Filters must be cleaned and/or changed regularly to maintain the dehumidification performance of the unit (at least once a year, depending on the conditions of use).
