Air Dehumidification

The processes that take place during air dehumidifica­tion are based on physical laws. We will try to describe
these in a simplified form to give you a general idea
about the principle of air dehumidification.

The Use of REMKO Air Dehumidifiers

◊ No matter how well doors and windows are insu-

lated, dampness and moisture penetrate even thick
concrete walls.

◊ It can take up to 1 or 2 months for the water used in

the production of concrete, mortar, plaster, etc. to
dry.

◊ The moisture that penetrates brickwork as a result of

flooding is released very slowly.

◊ E.g. this is also the case regarding moisture con-

tained in materials in storage.

The moisture escaping from parts of buildings or materi­als (water vapour) is absorbed by the ambient air. Con­sequently the humidity of the air increases which results
in corrosion and in formation of mildew, decay, flaked
off paint and other unwanted damage.

The diagram below is an example of the corrosion rate
of metal at different air humidity levels.

There are two different ways of drying buildings:

1. By heating and exchanging the air:
The ambient air is heated to absorb moisture and ex-

pelled to the outside. However, the total generated
energy is lost with the expelled humid air.

2. By dehumidifying:
The humid air in the closed room is continuously de-

humidified based on the principle of condensation.

With respect to energy consumption, dehumidification
offers one important advantage:

Energy is only needed for the existing room volume.
The mechanical heat released during the dehumidifica­tion process increases the room temperature slightly.

When used properly, the air dehumidifier consumes
only approx. 25 % of the energy to be supplied accord­ing to the “heating and ventilation” principle.

Relative Air Humidity

Ambient air is a gas mixture which always contains a
certain percentage of water as water vapour.

This percentage of water is indicated in g per kg of dry
air (absolute water content).

1 m³ of air weighs approx. 1.2 kg at 20° C.
Depending on the temperature, each kg of air can only

absorb a defined quantity of water vapour. When this
quantity has been absorbed, the air is “saturated” and
has a relative humidity of 100 %.

Relative air humidity is defined as the ratio between the
percentage of water vapour contained in the air at the
moment in question and the maximum possible per­centage of the water vapour when the temperature is
the same.

The capacity of air to absorb water vapour increases
when the temperature rises. This means that the maxi­mum possible (= absolute) water content is increased
as the temperature increases.

As you can see, the corrosion rate is insignificant at a
relative air humidity of less than 50 % and at a humidity
rate of less than 40 %, it can even be ignored. When
the relative humidity exceeds 60 %, the corrosion rate
increases considerably.

This limit for damage caused by humidity also applies
for many other materials, such as powdery substances,
packing materials, wood, and electronic devices.

Water Vapour Condensation

The maximum possible amount of water vapour that
can be absorbed becomes higher when the air is
heated, but the water vapour content remains un­changed and consequently the relative air humidity is
reduced.

However, when the air is cooled, the maximum possi­ble amount of water vapour that can be absorbed is
continuously reduced although the water vapour quan­tity contained in the air remains unchanged and conse­quently the relative air humidity rises.

When the air is further cooled, the absorption capacity
with respect to the maximum amount of water vapour
possible is continuously reduced until it is equivalent to
the water vapour content. This is the dew point tem­perature.

If the air is cooled below the dew point, the water vapour
content will be higher than the maximum amount of wa­ter vapour possible.

Water vapour is expelled.

It condenses, is converted into water and thus extracted
from the air.

Steamed up window panes in winter or
steamed up bottles containing cold drinks are
typical examples of condensation.

The higher the relative air humidity is, the
higher the dew point temperature is and con­sequently the easier it is for the temperatures
to fall below the dew point.

Drying Materials

Building materials/buildings can absorb considerable
amounts of water; e.g. bricks 90-190 l/m³, heavy con­crete 140-190 l/m³, calcareous sandstone 180-270 l/m³.
Damp materials such as brickwork dry as described be­low:

◊ The moisture contained in the material

flows from the inside to the surface

◊ Evaporation takes place on the sur-

face = water vapour is absorbed by the
ambient air.

◊ The air augmented with water vapour continuously

circulates through the REMKO air dehumidifier. It is
dehumidified and leaves the unit in a slightly warm
state to absorb water vapour again.

◊ This allows the moisture contained in the material to

be continuously reduced; the material becomes dry.

The resulting condensa­tion is collected in the de­vice and drained.

The air current is cooled on its way through/via the
evaporator until its temperature falls below the dew
point. The water vapour condenses, is collected in a
condensation tray and drained.

Condensation Heat

The energy transferred from the condenser to the air
consists of:

◊ The heat that was previously extracted in the evapo-

rator.

◊ The electric operating power.
◊ The condensation heat released by liquefying water

vapour.

When the liquid is converted into a gaseous state, en­ergy must flow back. This energy is called evaporation
heat. It does not cause the temperature to rise but is
used for the conversion from the liquid to the gaseous
state. Conversely, energy is released when gas is lique­fied, and this energy is called condensation heat.

The energy produced from evaporation and condensa­tion heat is identical.

For water this is 2250 kJ / kg ( 4.18 kJ = 1kcal )
This shows that a relatively high amount of energy is re-

leased through water vapour condensation.
If the humidity to be condensed is not generated by

evaporation within the room, but supplied from the out­side, e.g. by ventilation, the condensation heat released
thereby contributes to heating the room.

When materials or rooms are to be dried, the heat en­ergy flows in a cycle, i.e. it is consumed during evapora­tion and released during condensation.
A larger amount of heat energy is generated when sup­plied air is dehumidified which is expressed as a rise in
temperature.

Generally, the time needed for drying does not depend
on the unit capacity, but is determined by the speed at
which the material or the parts of the building release
the moisture contained in them.

Description of the Unit

The unit has been designed for automatic, universal,
smooth air dehumidification. Its compact dimensions
make it easy to transport and set up.

The unit works on the principle of condensation. It is
equipped with a closed-loop cooling system, a quiet fan
requiring little maintenance and a power cord with plug.

The unit has a control panel with an LCD display to con­trol the functions. The unit can be set to automatically
switch on and off at specific times via the timer function.

A fully-automatic control, the condensation collector with
integrated overflow prevention mechanism and the con­nection adapter for direct drainage of condensation en­sure that the unit run smoothly in smooth operation.

The unit meet the basic safety and health requirements
found in the relevant EU regulations. It is safe and easy
to operate.

Unit setup locations

The unit is used in rooms where dry air is a priority to
avoid consequential financial losses (e.g. as a result of
a buildup of mildew).

The unit is primarily used to dry and dehumidify:

◊ Living rooms, bedrooms, showers or basements.
◊ Kitchens, weekend houses, caravans.

And to keep the following dry on an permanent basis:

◊ Storage areas, archives, laboratories.
◊ Bathing, washing, changing rooms, etc.

Function
The unit works on the principle of condensation.

The fan sucks the moist ambient air into the back of the
unit via the air filter, the evaporator and the condenser
located behind the evaporator.

Heat is extracted from the ambient air at the cold
evaporator. The ambient air is cooled until it falls below
the dew point and the water vapour contained in the air
turns into condensation or frost on the evaporator fins.

Diagram of how the unit functions

The dehumidified, cooled air is reheated in the con-
denser (heat-exchanger) and then released at a tem­perature of approximately 5 degrees above room tem­perature.

This air, which is now drier, is mixed again with the am­bient air. The humidity of the air is gradually reduced to
the desired relative humidity through the continuous cir­culation of ambient air by the unit.

6

Depending on the air temperature and the relative hu­midity, the condensed water drips out steadily or only
during periodic defrosting phases into the collection
tray and then into the condensation collector beneath
it through the integrated drainage lines.

A float regulator flap is installed in the condensation col­lector that interrupts dehumidification operation via a mi­croswitch when the collector is full.

The unit switches off and the LCD display "Collector full“
lights up. It goes off again when the condensation col­lector is emptied and replaced. The unit then restarts af­ter a delay of approximately 2 minutes.

For unsupervised, continuous operation of the unit, the
condensation is continuously drained via an external
water hose.

Follow the instructions below to ensure the to optimum,
economical and safe operation of your unit.

◊ The unit must be securely placed in an upright posi-

tion so that condensation can drain freely into the
condensation collector.

◊ If possible, place the unit in the middle of the room to

ensure optimum air circulation.

◊ Maintain a minimum distance of 50 cm to walls.

◊ If the unit is in operation in a dusty environment, the

appropriate service and maintenance measures are
to be undertaken in accordance with the specific

Initial Operation

Prior to initial operation or to meet local requirements,
the air intake and outlet openings must be inspected for
foreign bodies and the air intake filter for dirt.

Blocked or dirty grilles and filters must be cleaned im­mediately. See chapter “Maintenance and Service“.

Important instructions prior to operation

◊ Extension cords must be sufficiently thick.
◊ Extension cords can only be used if they are com-

pletely extended or rolled up!

◊ The condensation collector must be inserted prop-

erly.

Otherwise the unit does not work!

At room temperatures below 10 °C and a relative
humidity of less than 40 %, we no longer guaran-

G

tee that the unit performs efficiently.

Initial operation of the unit

1. Insert the power plug into a correctly fused plug
socket.

230V / 1~ / 50 Hz / 10 A.

Unit operating modes

The unit has four operating modes:

1. AUTOMATIC 45%-55%
In this operating mode, the unit dehumidifies for one

hour at a low fan speed regardless of the humidity
measured in the room. After this time period has
elapsed, the unit dehumidifies automatically. The re­quired fan speed is set automatically by the unit.

2. COMFORT 55%-65%
If the integrated sensor measures a humidity level of

more than 65%, the unit dehumidifies.
If the humidity falls below 55%, the unit no longer de-

humidifies. If the humidity rises above 65%, the unit
dehumidifies again. The fan speed can be set as
necessary.

3. MAXIMUM
In this operating mode, the unit dehumidifies continu-

ously after being switched on regardless of the hu­midity measured in the room. The fan speed can be
set as necessary.

4. VENTILATION
In this operating mode, the air in the room is circu-

lated. The unit does not dehumidify. The lowest fan
speed is set.

The fan remains in continuous operation until the
unit switches off to ensure that the integrated sen-

G

sor can always correctly measure the humidity.

2. Open the air flap on the top of the unit.

Instructions for unit operation

Automatic defrost

◊ After being switched on, the unit functions fully auto-

matically until it is switched off by a control mecha­nism activated by the float when the condensation
collector is full.

◊ If, during operation, the power supply is interrupted,

the unit does not switch on again automatically after
power has been restored. If a timer function was pro­grammed, it is deleted.

◊ If the unit is in operation with an external condensa-

tion hose in continuous operation, please read the
applicable section on this page.

◊ If the unit was switched off manually by the “On/Off”

button or by the float mechanism, the compressor
switches on again only after a delay of approximately
5 minutes.

This safety mechanism prevents the compressor
from overloading.

◊ The fan remains in continuous operation until the

unit switches off to ensure that the integrated sensor
can always correctly measure the humidity.

Information on dehumidification performance
The dehumidification performance is dependent only on

the spatial composition of the room, the room tempera­ture, the relative humidity and following the instructions
in the chapter entitled “Setup”.

The maximum dehumidification performance is
achieved by opening the air flap completely.

The higher the room temperature and the relative hu­midity, the greater the dehumidification performance is.

For use in residences, a humidity level of approximately
45 to 60 % is sufficient while a humidity level of 40 to 45
% may not be exceeded in storage areas, archives, etc.

The humidity contained in the ambient air condenses
when cooled and covers the evaporator fins with frost or
ice depending on the air temperature and the relative
humidity. This frost or ice buildup is automatically de­frosted from the unit.

D

Condensation collector

It is necessary to empty the integrated condensation
collector from time to time.

When the collector is full, the dehumidification mode is
interrupted and the Symbol E appears on the display.

E

The integrated automatic defrost sys­tem switches the defrost cycle on
when necessary.

During the defrost phase, the dehu­midification mode is briefly inter­rupted.

The Symbol D appears on the dis­play.

1. Carefully pull out the collector to­wards you.

2. Pour the condensation into a
drain.

3. Clean the collector with a clean
towel.

4. Carefully reinsert the collector
into the unit.

5. Keep in mind that the unit only
starts when the collector has
been correctly inserted.

The Symbol E disappears from
the display and the unit begins to
work again fully automatically.

Setting the air outlet direction
The dehumidified ambient air is expelled from the top of

the unit. The adjustable air flap can be used to change
the direction of the air being expelled.

1. To open the air flap, press on the
rear surface.

The front side opens upwards. You
can adjust the direction of the air
any way you want.

2. If possible, create a flow of air going upwards by
opening the flap completely.

3. Make sure that nothing is blocking the air from being
expelled.

This is the only way to guarantee optimum unit op-

eration.

4. Make sure that sensitive objects, such as plants in
the room, are not directly in the path of the expelled
air.

Continuous operation with an external condensa­tion hose.

The unit must be equipped with a connection adapter on
the left side. A standard 1/2" water hose can be con­nected here.
