Electric moisture absorber – dehumidifier

The electrical moisture absorber , also known dehumidifier reduces the moisture associated with condensation . It is a simple and inexpensive to set up a ventilation alternative.

Principle of the electric moisture absorber The electric moisture absorber is a compact device that can dehumidify the air by controlling the humidity :


Ambient air is sucked through a ventilation system.
The air condenses and turns into water.
Water is collected in a tray which is empty at progressively.

Advantages of the absorber or dehumidifier

absorbs up to 30 liters of water per 24 h (depending on model); very useful in kitchens, bedrooms, bathrooms or other damp;
comes in several models depending on the size of the surface to be treated; Ease of use: Ignition is via a single button; requires no cartridge or refill;
opportunity to save energy by setting off the night just in case of subscription EDF taking into account the peak hours;

How to choose a dehumidifier? Characteristics to watch on a dehumidifier to :

extraction of its capacity (in liters per hour or liters per day)
the discharge of the water recovered (in a bin or removed by a pipe to be connected on an outlet or outside) system
With humidistat or not (with a humidistat, the desired humidity level is adjustable and the dehumidifier will start and stop automatically depending on the selected rate)
The air flow expressed in cubic meters per hour m3 / h (the higher the flow, the higher the wind is strong and will project an air dry away from the dehumidifier )

Dehumidifiers Capacity is measured in liters per hour or liters per day to a standard that is to be tested at a temperature of 30 degrees and humid atmosphere of 80% RH ( humidity relative).

Small dehumidifiers can remove less than 2 l / day are useful for a cabinet or closet.

The electric dehumidifiers with a capacity of 5-60 liters per day are ideal for a room or a damp house or volumes of medium importance.

The dehumidifier capable of removing more than 60 liters per day (up to more than 200 l / d for larger) are required to dehumidify a warehouse, inventory, library, a museum, a flooded home and dry materials after water damage.

Always remember to take a safety margin by choosing a dehumidification system capable of removing more water from the moist air that locals can not produce.

A pool for example produces a lot of water through evaporation.

Same for local low-temperature 10-12 °, a dehumidifier electrical stronger is needed.

In the case of temperatures below 10 °, a gas hot air dehumidifier or air dryer is preferred because they work well.

If the dehumidifier is in a cold room, prefer models of air dehumidification with heat .

Some tips on the use of a dehumidifier condensation

A wet basement can be dehumidified very effectively with a dehumidifier , it is best to close all openings to the outside which will allow the dehumidifier to operate only for the volume of air in the basement and not air from outside.

For the same problem humidity , a dehumidifier will work at high speed but too low if ventilation is at low speed.

Must adapt the dehumidifier depending on your knowing the speed of the ventilation speed dehumidifier affects noise.

A very local wet require a dehumidifier more powerful than a little piece wet .

A dehumidifier with humidistat provides automatic operation: after selecting the humidity wanted, electric dehumidifier will go into operation if the air humidity is greater than the selected rate and stop when moisture air correspond to the selected one.

In case of power failure, an electric dehumidifier with humidistat mechanical (manual humidistat) restarts that is not the case of dehumidifiers equipped with an electronic humidistat that require pressing the start.

For a second home, choose a dehumidifier with mechanical humidistat manual .

A mechanical humidistat is more resistant to high humidity that electronic humidistat .

More local is more heated dehumidifier air will be effective.

Always choose a dehumidifier power more powerful than necessary if the compressor may run too intensely wearing more quickly and prematurely compared to a dehumidifier a bit oversized.

Combine a ventilation system, heating and air dehumidifier electrical accelerates the drying of the air and materials.

You’re a little present or want to dehumidify a second home, choose a dehumidifier without drain pan condensate (reclaimed water) for a dehumidifier with continuous drainage (water is discharged through a pipe).

Below 5 °, a dehumidifier condensation no longer manage to collect water, ice will form could damage the dehumidifier .

The permanent drainage of dehumidifiers allows removal of water condensate in a sewer, sink, pipe, shower, bathtub …

A drain pump or the drain pump can be integrated in the dehumidifier reservoir to evacuate water automatically without manipulation.

The majority of electric dehumidifiers are equipped with an automatic cutoff when full tank.

In a very damp room , choose a dehumidifier whose flow can change the air about 3-4 times per hour and for a room of 100 m3 will require electric dehumidifier with a minimum capacity of 300 m3 / h.

For yards, prefer professional dehumidifiers , they are more robust, more powerful and generally provided solid wheels.

The filters electric dehumidifiers air should be cleaned at least once per month.
Some dehumidifiers filters are washable and permanent.

The dehumidifier should be placed in the wettest part of respecting the local electrical safety and common sense.

A dehumidifier placed in a chamber must be stopped when you settle to sleep, it must dehumidify the room not you!

The dehumidifier silica gel that operates at low temperature is ideal for cold areas and cold rooms.
