Air dehumidification
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
in the production of concrete,
mortar and plaster etc. may only
be diffused after 1-2 months.
– Even moisture trapped
in the masonry after highwater or 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.
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.
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
dehumidifier
25% of the energy that is
required for the
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).
1m3 of 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.

Drying of materials
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 air containing water vapour

Transfer of water vapour
to the ambient air
The condensation of
water vapour
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.
It then condenses to water.
Humidity is then removed from
the air.
As it flows through or over the evaporator, the air stream is cooled
to dew point. The water vapour condenses, and is collected
in a condensate trap from where it is drained off.
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 to does the dew point,
making it easier for the temperature
to fall below it.

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 the liquefying of 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,
Safety notes
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.
With drying operations,
a heat cycle is created,
whereby heat is consumed
for evaporation and released
for condensation.
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 were 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.

Unit description
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, low-noise and lowmaintenance fan, operating hours
counter and connection cable with
plug.
Fully-automatic electronic control,
a condensate container
with integrated overflow
protection (not AMT 115-E)
in addition to connection ports
for direct condensate drainage
help to ensure continuous faultfree 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.
Locations at which units are
used
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.
Operating sequence
Switching on the units
puts the electrical control
into operation.
The green indicator light
on the operating switch
illuminates.
Due to an automatic pressure
equalisation, the units start with
a time delay of around 10 seconds.
The fan extracts the moist room air
through the dust 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.
If the temperature sensor here
measures a pre-set minimum, it
activates a timer with a 30 minute
delay.
If the evaporator temperature
stops increasing during this period,
the cooling cycle switches to hot
gas defrosting after the timer
cycle.
The fan remains out of
operation during the defrosting
phase.
Schematic depiction of the workings of a REMKO air dehumidifier
As soon as the rime (ice) has been
defrosted and the temperature
at the probe has increased,
the unit switches back to normal
dehumidification mode.
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 dehumidifiers
work economically.
The cooled and dehumidified air
is re-heated by the condenser
(heat exchanger), and blown back
into the room through the outlet
grille.
The processed, dry, heated 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
temperature and the humidity,
only 30 - 40% electrical energy
is required, in accordance with
the output of the unit.
The units may be used
for the drying and
dehumidification of areas such as:
■
New buildings, industrial
buildings
■
Basements, storage rooms
■
Archives laboratories
■
Weekend homes, caravans
■
Bathrooms, wash rooms and
changing rooms etc.

The following procedure must
be followed when commissioning
units in conjunction with
a humidity switch:
1. Insert the adapter
into a properly fused mains
socket.
2. Place the humidity
switch in a suitable
location within the room

on the humidity switch.
5. Move the operating switch [2]
on the unit to position "I".
The units will switch on
automatically when the air humidity
in the room exceeds the pre-set level
on the humidity switch.
■
In order to prevent damage
to the condenser, the units are
equipped with a mechanism
that prevents the compressor
from being immediately
switched back on after it is
switched off
The compressor does not
switch back on until after
a waiting time of around one

Condensate
Depending on the air temperature
and the relative humidity, condensed
water will drip into the condensate
trap or into the condensate
container either continuously or only
during the defrosting phases.
The condensate is fed
into the condensate container below
via a connection nozzle (not AMT
45-E and AMT 115-E).
A float is located inside
the condensate container.
In the event that the container is
full, the float will activate a water
stop switch which will switch off
dehumidification mode.
To guard against accidental stops
caused by flooding water etc., this
switch does not activate until after
a time delay of 10 seconds.
The unit will switch off and
the yellow indicator light
on the control panel will illuminate.

To empty the condensate
container, the following procedure
must be followed:
1. Move the operating switch [2]
to the "0" (off) position.
Otherwise, the AMT 65-E and
AMT 85-E units would restart
immediately after the container
is removed.
2. Remove the condensate
container.
To do this, lift the container
slightly using the embedded
recessed grip and then pull it
carefully forwards and out.
NOTE
Beware of dripping
condensate.
After switching off the units,
the evaporator may continue
to defrost under the influence
of the ambient temperature.
5. Close the pouring opening
[E] and carefully insert
the condensate container back
into the unit.
NOTE
After being emptied,
the condensate container
incl. float must be checked
for damage, contamination etc.
6. Switch the unit back on using
the operating switch [2].
NOTE
The AMT 45-E units are
only fully functional if
the condensate container is
inserted properly.
D
To operate the units,
the condensate container must
always be inserted correctly
in the AMT 45-E.
In unattended permanent
operating mode, the condensate
should preferably be drained
into a lower-level flow.

AMT 115-E condensate drain
Due to their high dehumidification capacity, the AMT 115-E units are not
equipped with an internal condensate container.
The condensate drainage is to be provided by the customer in suitable
containers via the exterior unit connection nozzles (½").
The following variants (for example) are available to drain the condensate
water that arises:
Variant A
The water is collected
in a container that is provided
by the customer and that is
of sufficient size.
The container must be checked
regularly and emptied if necessary.
There is no overflow protection!
Variant B
The water is first collected
in a container and fed into a higher
drain via a separate submerged
pump or drained outside directly.
This variant is suitable
for installation locations with
an insufficient incline or without
a drain.
Shutdown
Move the operating switch
to the "0" (off) position.
If the units are inactive for longer
periods, disconnect them from
the mains power supply.
Empty the condensate container
and dry with a clean cloth.
Beware of dripping condensate!
When storing the unit, cover
with a plastic sheet/foil if
necessary and store in an upright
position in a sheltered and dry
location.
To save space when storing,
the units can be stacked on top of
one another.
For this purpose, they are
equipped with rubber pads
on the base plate.
Variant C
The water is fed into a lower
drain via a ½“ hose pipe.
This variant enables unattended
permanent operating mode.
NOTE
These variants can also be used in the same way for continual
condensate drainage for all other unit types.

ATTENTION
An electrical safety check must
be carried out in accordance
with VDE 0701 after any work
on the units.
Troubleshooting
The units are manufactured
using state-of-the-art
production methods and tested
several times to verify their correct
function. However, if a functional
fault should occur, the unit should
first be checked in accordance with
the following list.
The unit does not start
■
Check the setting of
the operating switch. The green
indicator light should illuminate
■
Check the power supply and
the power fuse provided by
the customer 230V/1~/50 Hz
■
Check the power plug and
the cable for damage
■
Check the level and correct
positioning of the condensate
container
(not AMT 115-E)
■
Check the setting of
the humidity switch
(accessories).
The pre-set value must be
lower than the relative humidity
in the room
■
Check the humidity switch
adapter for damage and correct
positioning
The red indicator light
(Malfunction) illuminates
■
The cooling cycle is overloaded
or overheated
■
Before starting the unit again,
first identify the cause of
the malfunction.
Note that the re-start is
automatic after the cooling
process is complete!
The unit runs but does not
form any condensate
■
Check the room temperature
The operating range of the unit
is between 3°C and 32°C
■
Check the humidity of the air,
min. 40% RH required
■
Check the dust filter
for contamination and clean or
replace if necessary
■
Check the evaporator
and condenser fins
for contamination and clean if
necessary
■
Check the evaporator for ice or
rime formation.
If ice has formed, check
the functionality of
the automatic defrost and
the temperature sensor
■
If the unit fails
to function correctly after
the checks have been carried
out, an authorised specialist
!
ATTENTION
Work on the refrigerant
system and on the electrical
equipment must only be
conducted by a speciallyauthorised specialist!
