It is evident that the corrosion
rate below 50 % relative humidity
(RH) is low, and below 40 % is
negligible.
The corrosion rate increases
significantly above 60 % RH.
This threshold for damage as the
result of humidity also applies to
other materials, such as powdery
substances, packaging, wood and
electronic units.
Buildings may be dried in a variety
of ways:
1. By heating and air exchange:
The air in the room is heated
in order for moisture to be
removed and then this air is fed
outside. All of the energy that
is involved is lost together with
the moist air that is released.
2. By air dehumidification:
The moist air that is present
within an enclosed space is
continuously dehumidified
according to the condensation
principle.
The correlations occurring when
air is dehumidified are based on
physical laws.
These are depicted here in
graphical form in order to provide
you with a brief overview of the
principles of air dehumidification.
The use of REMKO
air dehumidifiers
■ Even if windows and doors
are well insulated, water and
moisture are still capable of
penetrating thick concrete walls.
■ The water required for setting
when producing concrete,
mortar and plaster etc. may only
be diffused after 1-2 months.
■ Even moisture trapped in the
masonry after a flood is released
very slowly.
■ The same is also true of
moisture contained in stored
materials for example.
The moisture (water vapour)
released from parts of a building
or materials is absorbed by the
surrounding air. As a result, the
moisture content increases, which
ultimately gives rise to corrosion,
mould, rot, peeling of paint and
other unwanted damage.
By way of example, the diagram
shows the corrosion rate of metal
in different levels of humidity.
Air dehumidification
With regard to energy
consumption, air dehumidification
has one distinct advantage:
Energy expenditure is limited
exclusively to the air volumes
present. The mechanical heat that
is released by the dehumidification
process is fed back into the room.
Under normal use, the air
dehumidifier uses approximately
25 % of the energy that is
required for the “heating and
ventilating” principle.
Relative air humidity
Our ambient air is a gaseous
mixture which always contains
a certain volume of water in the
form of water vapour. This volume
of water is specified in g per kg of
dry air (absolute moisture content).
1 m3of air weighs approx. 1.2 kg
at 20 °C
Depending on the temperature,
each kg of air is only capable of
absorbing a certain volume of
water vapour. Once this capacity
has been reached, the air is
referred to as “saturated” and has
a relative humidity (RH) of 100 %.
Relative humidity is understood
to mean the ratio between the
current quantity of water vapour in
the air and the maximum possible
quantity of water vapour at the
same temperature.
The ability of the air to absorb
water vapour increases as
the temperature rises. I.e. the
maximum possible (absolute)
water content becomes greater as
the temperature rises.
Corrosion speed
Rel. humidity %

Water vapour
condensation
Because the capacity for the
maximum possible volume of
water vapour increases as the air
is heated, the volume of water
vapour contained remains constant
and so relative humidity falls.
In contrast, because the capacity
for the maximum possible volume
of water vapour decreases as the
air is cooled, the volume of water
vapour contained remains constant
and so relative humidity increases.
If the temperature continues to
fall, the capacity for the maximum
possible volume of water vapour
is reduced so much so that it is
ultimately equal to the volume of
water vapour contained in the air.
This temperature is referred to
as the dew point. If the air is
cooled to below the dew point,
the volume of water vapour in
the air will become greater than
the maximum possible volume of
water vapour.
At this point, the water vapour
begins to precipitate.
This condenses to water and
moisture is removed from the air.
Examples of condensation include
steamed-up window panes in
winter, or the moisture on the
outside of a cold drinks bottle.
As the relative humidity of the air
increases, so too does the dew
point, making it easier for the
temperature to fall below it.
Building materials and structures
are capable of absorbing
considerable volumes of water,
such as brick 90-190 l/m³, heavy
concrete 140-190 l/m³ and
limestone 180-270 l/m³.
The drying of moist materials such
as masonry is effected as follows:
■ The moisture
moves from
the inside of the
material to its
surface
■ Evaporation occurs on the
surface = Transfer of water
vapour to the ambient air
■ The air containing water vapour
is constantly circulated through
the REMKO air dehumidifier.
The air is dehumidified and,
slightly heated, leaves the unit
in order to re-absorb water
vapour
■ In this way, the moisture
contained in the material is
reduced gradually
The material is dried!
The accumulated condensate is
collected in the unit and drained
off from there.

Safety notes
Condensation heat
The Energy transferred to the air
from the condenser consists of:
1. The amount of heat derived
beforehand in the evaporator.
2. The electrical drive energy.
3. The condensation heat released
by liquefying the water vapour.
Energy must be supplied when
liquid is converted into a gas.
This energy is designated as
evaporation heat. It does not
cause any increase in temperature,
but is required to convert a liquid
into a gas. Conversely, energy is
released when gas is liquefied,
this is designated as condensation
heat.
The amount of energy from
evaporation heat and condensation
heat is the same.
For water, this is:
2250 kJ/kg (4.18 kJ = 1kcal)
From this it is evident that the
condensation of water vapour
causes a large quantity of energy
to be released.
If the moisture that it is to be
condensed is not introduced by
evaporation in the room itself,
but from outside, e.g. through
ventilation, the condensation
heat released contributes to
the heating of the room. With
drying operations, a heat cycle
is created, whereby heat is
consumed for evaporation
and released for condensation.
When dehumidifying fed air,
a larger contribution of heat is
created, which manifests itself as
a temperature increase.
Generally speaking, the time
required for the drying process is
not only dependent on the output
of the unit, but is determined to
a greater extent by the speed at
which the material or building
section loses its moisture.
The units have been subjected to
extensive material, functional and
quality inspections prior to delivery.
However, dangers can result
from the units if they are used
improperly or not as intended by
untrained personnel.
The following notes
must be observed in full:
■ The units may not be installed
or operated in explosive
environments
■ The units must not be installed
or operated in atmospheres
containing oil, sulphur, chlorine
or salt
■ The units must be installed
upright and in a stable position
■ The units must not be exposed
to direct jets of water
■ An unobstructed air inlet and
air outlet must be guaranteed
at all times
■ The air-inlet grille must always
be kept free of dirt and loose
objects
■ The units must not be covered
during operation
■ Never stick foreign objects into
the units
■ The units must not be
transported while they are
running
■ The units may only be
transported upright
■ All electrical cables on the
outside of the units must be
protected against damage
(e.g. by animals etc.)
■ Before each change of location,
the condensate container must
be emptied
Extensions to the connection
cable must only be conducted
by authorised specialist
electricians, taking into
consideration the unit power
consumption, cable length and
local use.
Work on the refrigerant
system and on the electrical
equipment must only be
conducted by a specially-
authorised specialist!

Unit description
Operating sequence
The units are switched on and off
by the hygrostat.
In dehumidification mode,
the “Dehumidification” indicator
light on the control panel
illuminates.
The fan extracts the moist room air
through the intake grill with filter,
evaporator and the condenser
behind.
Heat is removed from the room air
on the cold evaporator. The air is
then cooled to below dew point.
The water vapour contained in
the room air is then deposited
as condensate or rime on the
evaporator fins.
On the condenser (heat
exchanger), the cold and
dehumidified air is warmed up
again and discharged back into
the room via the outlet grill
with a temperature increase of
around 5 - 10 °C above the room
temperature.
The processed, dry air then re-
mixes with the room air.
Continuous circulation of the room
air through the unit gradually
reduces the relative humidity
(% RH) in the room to the desired
humidity level.
Depending on the room air
temperature and the relative
humidity, condensed water will
drip into the condensate trap
and then through the integrated
discharge nozzle into the
condensate container below either
continuously or only during the
defrosting phases.
A float is installed inside the
condensate container. In the event
that the container is full, the float
will activate a microswitch which
will switch off dehumidification
mode.
The units switch off and the
“container full” indicator light
on the control panel illuminates.
This extinguishes again when the
empty condensate container
is re-inserted.
The units then restart after
a switch-on delay of around
3 minutes.
In unattended continuous
operation with an external
condensate connection,
the condensate that occurs is
drained continuously via a hose
connection.
The units have been designed for
universal and straightforward air
dehumidification.
Their compact dimensions allow
the unit to be transported and set
up with ease.
The units operate in accordance
with the condensation principle
and are equipped with
a hermetically sealed refrigerant
system, heat gas defrosting,
low-noise and low-maintenance
fan and connection cable with
plug.
The fully automatic control,
the infinitely variable hygrostat,
the condensate container with
integrated overflow protection
and the connection nozzle for
condensate drainage guarantee
fault-free continuous operation.
The units conform to the
fundamental health and safety
requirements of the appropriate
EU stipulations.
The units are dependable and offer
ease of operation.
The units are used in all locations,
where dry air is a must and where
economic consequential damage
(such as that caused by mould)
must be prevented.
The units may be used for the
drying and dehumidification of
areas such as:
■ Living rooms, bedrooms,
shower rooms or cellar rooms
■ Laundry rooms, weekend
homes, caravans
■ Warehouses, archives

Adjusting the discharge
direction
The dehumidified room air is
discharged on the top of the unit.
The pivotable air flap [S] is used to
adjust the discharge direction.
Press the air flap’s rear surface [D]
to open it.
The front folds upwards. The air
direction can be adjusted infinitely.
The following notes must also be
observed in full:
■ If possible, open the air flap
completely to direct the air flow
upwards
■ Ensure that the air can
discharge without hindrances
This is the only way to
guarantee optimum unit
operation!
■ Ensure that sensitive objects
such as house plants are not
placed directly in the air flow
emerging from the unit
DS
Automatic defrost system
The moisture contained in the
room air condenses when cooling
and coats the evaporator fins
with rime or ice depending on the
air temperature and the relative
humidity (% RH).
The automatic defrost system that
is integrated in the unit switches
the defrost cycle on if required.
The rime or ice that has
accumulated on the exchanger
surfaces is defrosted using heat gas
as required.
This defrosting method is
particularly fast and effective, and
guarantees high dehumidification
performance.
Dehumidification mode is only
paused for a short time during the
defrost phase.
The “Defrost mode” indicator light
indicates that the defrost cycle is
running.
NOTE
If the room temperature is
sufficiently high, the surface
of the fins will not be cold
enough for rime formation to
occur, rendering defrosting
unnecessary.
Therefore, the air dehumidifier
works economically.
Adjusting units/moisture
The unit’s dehumidification power
is entirely dependent on the
conditions inside the room, the
room temperature, the relative
humidity and observance of the
notes in the “Setting up”chapter.
The higher the room temperature
and relative air humidity,
the higher the dehumidification
power.
A relative humidity of around
45 to 60 % is sufficient in living
rooms. The air humidity should not
exceed 40 to 45 % in warehouses,
archives, etc.
Adjust the hygrostat
for the recommended
air humidity
in living rooms.
Approx. 50 %.
Adjust the hygrostat
for the recommended
air humidity
in archives.
Approx. 40 %.
Adjust the hygrostat
for the minimum
air humidity in the
installation room.
The units work in continuous
operation in this position!
NOTE
The maximum possible
dehumidification power is only
obtained when the air flap is
opened completely.
