How to choose the most suitable dehumidifier?

The correct relative humidity of rooms should be in the range of 40-60% at a temperature of about 20 °C. Too low or too high a water vapor content in the air is unfavorable for people working in the rooms.

Excessive humidity leads to accelerated corrosion and disrupts the operation of machines and equipment. This creates very good conditions for the growth of mold, which forms on damp walls and ceilings.
Therefore, it is important to avoid prolonged humidity at all costs. For this, it is best to rent an air dryer, which will effectively reduce excessive humidity.

Where are dehumidifiers used?
Dehumidifiers are used in many situations, depending on their parameters, when the humidity in the rooms is high. They are most often used when drying newly built buildings and rooms after general renovation.

Masonry and painting work or pouring floors - these are the most typical activities in which excessive humidity is created on the walls and floors and it is worth using an air dryer.

The second typical group of uses for an air dehumidifier is the restoration of rooms flooded by floods and sudden rainfall. The third group where an air dryer is most often used is plumbing or sewage pipe failures.

If the humidity in the air quickly returns to a very high level after using a dehumidifier, it can be assumed that it is caused by constant water seepage into the walls, as is often the case in basements of old buildings, the foundations of which lack moisture insulation.

What to look for when choosing a dehumidifier?
When renting a dehumidifier, pay attention to several basic parameters of the device:
Dehumidification capacity - this is an indicator that indicates the amount of water removed from the air per day (measured at the temperature and humidity specified by the manufacturer), Air flow rate - the number of cubic meters of air that flows through the dehumidifier per hour, Water tank capacity - when the tank is full, the dehumidifier automatically turns off, so its volume should be carefully selected according to the humidity and size of the room to be dehumidified. The choice should also depend on the possibility of draining into a larger tank or directly into the sewer, Energy consumption - since a dehumidifier is a machine that often works continuously for a long time, it is more advantageous to use professional branded devices.

Performance parameters largely depend on the type of dehumidification technology used. Devices operating on the principle of condensation or adsorption of water from the air are available on the market.

Will a condenser or adsorption dryer be better?

Condensation and adsorption dryers differ fundamentally in the way they work. Condensation devices use evaporators and condensers, whose task is to adequately cool (below the dew point) the humid air and condense the water vapor. On the other hand, adsorption dehumidifiers are equipped with an absorber (rotor) that absorbs moisture from the air and then dries it with hot air.

Different technologies have a direct impact on the performance of dehumidifiers under certain environmental conditions. In adsorption dryers, the performance remains constant regardless of the ambient temperature. Adsorption dehumidifiers work effectively even at temperatures below zero, which allows them to be used in unheated rooms. Condensation devices, on the other hand, work most effectively at temperatures above 20 °C and relative humidity above 60%. Adsorption devices are more susceptible to contamination due to the use of a rotor.

If we are not sure which type and model of dehumidifier will be optimal, we can consult with experts from the equipment rental company. Just describe the conditions under which we want to use the device to get the machine that best suits our needs.
