This shows that the rate of corro-
sion below 50% relative humidity
(R H) is insignificant and below
40% R H can be disregarded.
From 60% R H, the rate of corro-
sion increases considerably. This
moisture damage limit applies also
to numerous other materials, e.g.
powders, packaging, wood or elec-
tronic units.
Buildings can be dried out in differ-
ent ways:
1.
By heating and air exchange:
The room air is heated to absorb
moisture in order to then be dis-
charged to the atmosphere. The
total input energy is lost with
the discharged, moist air.
2.
By dehumidification:
The moist air in an enclosed
room is continuously dehumidi-
fied by the condensation princi-
ple.
The interrelated processes that
take place during dehumidification
are based on physical laws.
These are to be illustrated here in
simplified form in order to explain
the principle of dehumidification.
The use of
REMKO dehumidifiers
– No matter how well windows
and doors are insulated, damp
and moisture can penetrate
even through thick concrete
walls.
– The water volumes required for
binding concrete, mortar, plas-
ter, etc. are diffused out initially
after 1-2 months under certain
circumstances.
– Even moisture that has penetrat-
ed masonry following high wa-
ter or flooding, is only released
very slowly.
– This applies similarly, e.g. also to
moisture contained in deposited
materials.
The moisture (water vapour) es-
caping from buildings or materials
is absorbed by the ambient air. This
increases their moisture content
and ultimately results in corrosion,
mould, rot, peeling of paint coat-
ings and other unwanted moisture
damage.
The diagram opposite shows an
example of the rate of corrosion,
e.g. for metal at different humidity
levels.
Dehumidification
In terms of energy consumption,
dehumidification has one decisive
advantage:
Energy expenditure is restricted
solely to the existing room volume.
The mechanical heat released
through the dehumidification proc-
ess is returned to the room.
With correct use, the dehumidi-
fier only uses about 25% of the
energy that would be needed for
the „heating and ventilation”
principle.
The relative humidity
Our ambient air is a gas mixture
and contains always a certain
amount of water in the form of
water vapour. This water volume is
expressed in g per kg dry air (abso-
lute water content).
1m3air
weighs about 1,2 kg at 20 ° C
Depending on the temperature,
each kg of air is only able to ab-
sorb a certain amount of water va-
pour. When this absorptive capac-
ity is reached, reference is made to
“saturated” air; this has a relative
humidity of (R H) 100%.
Relative humidity is therefore un-
derstood to be the ratio between
the amount of water vapour cur-
rently contained in the air and the
maximum water vapour volume at
the same temperature.
The ability of air to absorb water
vapour increases with increas-
ing temperature. This means that
the maximum (= absolute) water
content increases with increasing
temperature.

The condensation of
water vapour
Since the maximum water vapour
volume increases when the air is
heated, the contained water va-
pour volume remains the same
however, this results in a reduction
of the relative humidity.
In contrast, when the air is cooled,
the capacity to absorb the maxi-
mum water vapour volume reduc-
es, the water vapour volume con-
tained in the air remains the same
and the relative humidity increases.
If the temperature falls further, the
capacity to absorb the maximum
water vapour volume is reduced
until it is equal to the contained
water vapour volume.
This temperature is called the dew-
point temperature. When the air
is cooled below the dew-point
temperature, the contained water
vapour volume is larger than the
maximum water vapour volume.
Water vapour is released.
This condenses to water. The air is
relieved of moisture.
Examples of condensing are misted
windows in winter or misting of a
cold drinks bottle.
The higher the relative humidity,
the higher the dew-point tempera-
ture, which is easier to fall below.
Building material and structures
can absorb considerable amounts
of water, e.g. bricks 90-190 l/m³,
heavy concrete 140-190 l/m³,
sand-lime bricks 180-270 l/m³.
The drying of moist materials, e.g.
masonry, takes place as follows:
■ The contained
moisture
moves from
within the
material to
its surface
■Evaporation takes place on the
surface = change to water va-
pour in the ambient air

■The air enriched with water va-
pour continuously circulates the
REMKO dehumidifier. It is de-
humidified and leaves the unit
at a slightly higher temperature
to absorb water vapour from
anew.
■In this way, the moisture con-
tained in the material is gradu-
ally reduced

The air flow is cooled on its way through or via the evaporator to

Heat of condensation
The energy transferred from
the condenser to the air is
composed of:
1. Heat energy extracted from the
evaporator.
2. Electrical drive power.
3. The heat of condensation re-
leased through the condensation
of water vapour.
For the change from a liquid to
a gaseous state, energy is neces-
sary. This energy is termed heat of
evaporation. It does not cause any
rise of temperature, it is only nec-
essary for the change from a liquid
to a gaseous state. Vice versa,
energy is released during the liq-
uefaction of gas, which is termed
heat of condensation.
The amount of heat of evaporation
and condensation is the same.
For water, this is:
2250 kJ/kg (4.18 kJ = 1kcal)
This shows that a relatively large
amount of energy is released
through the condensation of water
vapour.
If the moisture to be condensed is
not introduced through evapora-
tion in the room itself, but from
outside, e.g. via ventilation, the
heat of condensation released in
the process contributes towards
room heating. In drying processes,
the heat energy is recirculated,
which is consumed during evapo-
ration and released during con-
densation. The supplied air during
dehumidification creates a large
amount of heat energy, which is
expressed as a rise of temperature.
The time necessary for drying
normally does not depend only on
the unit capacity, but is rather de-
termined by the rate at which the
material or parts of the building
release their moisture.

Device Description
The units are designed for univer-
sal and problem-free dehumidifica-
tion.
Owing to their compact size, they
are easy to transport and install.
The units operate according to the
condensation principle and feature
a hermetically sealed refrigeration
system, low noise and mainte-
nance circulating fan, operating
hour counter and connecting cable
with plug.
Fully automatic electronic con-
trol, condensate container with
integrated overflow protection
(not with AMT 110-E) as well as
connections for direct condensate
removal ensure trouble-free con-
tinuous use.
The units comply with the fun-
damental safety and health re-
quirements of the permanent EU
regulations.
The units are reliable and easy to
operate.
Unit applications
The units are used wherever
dehumidication is necessary
and consequential damage (e.g.
through mould formation) is to be
prevented.
The units are also suitable for dry-
ing and dehumidification of:
■New buildings, industrial build-
ings
■Cellar rooms, storage rooms
■Archives, laboratories
■Weekend homes,
caravans
■Bathrooms, washrooms and
changing rooms, etc.
As soon as the frost (ice) has de-
frosted and the temperature at the
sensor rises again, the unit switch-
es back to normal dehumidification
operation.
At a sufficiently high room tem-
perature, the gill surface is not cold
enough for the formation of frost
so that defrosting is unnecessary.
This makes dehumidifiers particu-
larly economical in operation.
At the condenser (heat exchang-
er), the cooled and dehumidified
air is reheated and blown back into
the room via the air outlet.
The conditioned, drier and heated
air mixes with the room air again.
Due to the constant circulation of
the room air through the unit, the
relative humidity in the room is
gradually reduced to the required
humidity (% R.H).
Depending on the room tem-
perature and humidity, only about
30-40% of electrical energy is
required depending on the unit
cooling capacity.
Sequence of functions
The electronic control is activated
when the unit is switched on.
The green pilot light in the switch
illuminates.
Owing to automatic pressure
equalisation, the units start with
a delay of about 10 seconds and
then operate in continuous duty.
The circulating fan sucks the moist
room air via the dust filter, evapo-
rator and downstream condenser.
At the cold evaporator, heat is
extracted from the room air and
cooled to below the dew point.
The water vapour contained in the
room air deposits as condensate or
frost on the evaporator fins.
When the temperature sensor
measures a specific minimum value
here, a timer is activated with a
delay of 30 minutes.
If during this time the evaporator
temperature does not rise again,
the cooling circuit is switched to
hot gas defrost after the time has
elapsed.
During the defrost phase, the cir-
culating fan is off.

■The room to be dried or dehu-
midified must be closed with
respect to the ambient atmos-
phere
■Open windows, doors, etc.
as well as frequent entering
and leaving the room must be
avoided as far as possible
■If the units are used in dust-lad-
en environments or in stables,
care and maintenance measures
specially adapted to the particu-
lar conditions must be taken
■The unit capacity is solely
dependent upon the spatial con-
ditions, room temperature, rela-
tive humidity and observance of
the installation instructions

Operation with a hygrostat
The REMKO hygrostat (accessory)
is supplied with a special adapter
plug.
Commissioning of the units in con-
junction with a hygrostat and its
operation take place as follows:
1. Plug the adapter plug into a cor-
rectly protected socket-outlet.
2. Place the hygrostat at a suitable
point in the room to be dehu-
midified. Not in the immediate
vicinity of the unit and heat
sources.
3. Plug the mains plug (or a cable
extension) into the adapter plug.
4. Set the required humidity on the
hygrostat.
5. Set the operating switch [2] on
the unit to the position “I”.
The units switch on automatically
when the prevailing humidity is
higher than the value preset on the
hygrostat.
The units now operate fully auto-
matically until the relative humid-
ity (% RH) is reached or normal
switch off takes place via the float
switch in the condensate container
(not with AMT 100-E). In this case,
the yellow “container full” pilot
light illuminates.
NOTE
Clogged outlets and filters
must immediately be cleaned
or replaced.
NOTE
At room temperatures below
10°C and a relative humidity
below 40% , economical/ef-
ficient use of the unit is not
ensured.

REMKO AMT

Unit operation with hose con-
nection
The condensate traps [K] of the
AMT 55 and 80-E are provided
with a connection [A].
A standard water hose [S] can be
connected to this connection after
removing the condensate con-
tainer.
The discharge hose [S] is not
contained in the factory scope of
supply.
With the AMT 40-E, connection of
the hose takes place directly to the
connection [D] of the condensate
container.
For unit operation, the condensate
container must always be placed
correctly in the AMT 40-E.
The condensate must preferably
be discharged to a lower located
outlet in unsupervised continuous
duty.
When using a collecting container
(container, bucket, etc.), the unit
must be installed at a raised level.
Further ideas, see next page!
3. Carefully place the container
outside the unit and open the
sealing cover [F] of the drain
opening [E].
4. Pour the water into a drain.
5. Close the drain opening [E]
again and carefully place the
emptied condensate container
back in the unit.
6. Switch on the unit again via the
operating switch [2].
Condensate
Depending on the air tempera-
ture and relative humidity, the
condensed water drips steadily or
only during the defrost phases in
the condensate trap or condensate
container.
Via a connection (not with AMT
40-E and 110-E), the condensate
flows into the condensate con-
tainer located below.
In the condensate container is a
float switch which interrupts dehu-
midification via a water stop switch
when the container is full.
For protection against unintention-
al shut-off with splashing water,
etc., this protective unit initially
switches off with a delay of 10
seconds. The unit switches off and
the yellow pilot light on the control
panel lights up.
The procedure for emptying the
condensate container is as follows:
1. Set operating switch [2] to posi-
tion “0” (Off).
Otherwise, the units AMT 55-E
and AMT 80-E would immedi-
ately restart after the container
is removed.
2. Remove the filled condensate
container.
For this purpose, lift the con-
tainer slightly via the recessed
handle and carefully pull out.
NOTE
The AMT 40-E units are only
functional with correctly
placed condensate container.
NOTE
After each emptying, the
condensate container including
float switch must be checked
for any damage, fouling, etc.
NOTE
Attention must be paid to
dripping condensate.
After switching off the unit,
the evaporator can continue to
defrost under the influence of
the ambient temperature.

In case of longer
standstills, disconnect
the equipment from
the power mains.
The condensate container must
be emptied and dried with a clean
cloth.
Pay attention to dripping conden-
sate!
For storage purposes, the units
should be covered with plastic/
sheeting and stored in an upright
position in a protected and dry
location.
The units can be stacked one on
top of the other for space-saving
storage.
For this purpose, they are provided
with special rubber pads on the
base plate.
Variant A
The water is collected in a suffi-
ciently large dimensioned container
to be provided locally.
The container must be checked
regularly and emptied as necessary.
No overflow protection is pro-
vided!
Variant C
The water flows via a hose into a
lower located drain.
This variant enables unsupervised
continuous duty.
Condensate drain AMT 110-E
AMT 110-E units are not provided with an internal condensate container
due to their high dehumidification capacity.
Condensate discharge must take place locally into suitable containers or
via the external unit connection.
The following variants are available for discharge of the produced con-
densate water:
Variant B
The water is initially collected in a
container and pumped to a raised
outlet or to the outside via a sepa-
rate submersible pump.
This variant is suitable for installa-
tion sites without sufficient gradi-
ent or without drain.
Shutdown
NOTE
These described variants can be used analogous also for all other
unit types for continuous condensate discharge.
CAUTION
The units must be secured
after stacking to prevent them
falling over and against unau-
thorised access.
