The dehumidifier removes water from an airflow through, and
the removed water is carried away from the dehumidifier with
the regeneration air (henceforward called reg.-air).
Water adsorption and -extraction takes place in an rotor made
of water resistant silica gel.
The air flows in the dehumidifier divides the rotor in three
parts : drying part, cooling part, reg.-part.
Two separate air flows goes through the rotor as this:
- the main air (moist air inlet) goes through the drying
part, and leaves the dehumidifier as dry air
- a part of the reg.-air goes through the cooling part, and
will be warmed. The total reg.-air is then heated to
130C. This warm reg.-air now goes through the reg.-part
and the energy is used for evaporation of the adsorbed
water. This water vapour now leaves the dehumidifier
within the reg.-air. (see principle fig.1, page 2 ).
The two air flows are fixed and the rotor turns - this gives
an automatic process of simultaneous water adsorption and wa-
ter extraction.
The inlet conditions of the air to be dried, determines how
much water the dehumidifier will remove.
On page 8 the capacity diagram shows how much water will be
removed per kg air going through.
- inlet air conditions 20C, 60 %RH, gives water content 8,7
g/kg
- the diagram shows then dry air condition of X= 2,8 g/kg
- removed per kg air is then: 8,7 - 2,8 = 5,9 g/kg
Dry air flow is nominal 2000 m3/h= (x 1,2) = 2400 kg/h
Capacity, removed water per hour = 2400 x 5,9 = 14160g/h
= 340 kg/24h
- at 400V.
The temperature of the dry air is higher than for the inlet
air. This is caused by the evaporation heat release and heat
gain from the rotor. The temperature is shown to be 42C.
1. PRINCIPLE OF OPERATION.
CAPACITY DIAGRAM R902:
Example:
Capacity CR2000 at this condition:
Page 3
Dehumidifiers in the CR range are used for dehumidification
of ambient air at normal atmospheric pressure. This can be
an installation for moisture control in an unheated store
room, in a water work building, production room for hygro-
scopic materials... - with the dehumidifier in a separate
installation.
The dehumidifier also can be used as a part of a bigger air
treatment system. Here the dehumidifier often will be placed
in a by-pass to the main system.
In this case the pressure in the main system will influence
the dehumidifier - and your supplier must be contacted, as
this can influence the capacity of the dehumidifier.
Normally the dehumidifier will be placed in a wall bracket
or in a frame placed on the floor. Both parts can be sup-
plied as options.
The air to the dehumidifier should be free from solvents or
other explosive components, and should be free from pollu-
tion from solid particles and chemical substances ( ex.
acids, bases, oil vapours, exhaust gases...)
- max. humidity ...................... 100 %RH
- max. temperature ................... 35C
- max./min. pressure ................. ambient +/- 500Pa
2. APPLICATIONS.
For air to the dehumidifier the following limit values
must be respected :
The CR range is for indoor, stationary installations.
Should not be placed in rooms with possibility for free wa-
ter on the cabinet.

(green) indicates power supply, and should always be
illuminated when the dehumidifier is operating.
If the dehumidifier is not operating when HL1 is illuminated
the connected hygrostat might have broken ( humidity OK).
(red) indicates thermal switch-off. HL2 should never
be illuminated when the dehumidifier is operating.
Thermal switch-off can be one of the following reasons:
- overload relays for process air fan, reg.-air fan, gear-
motor
- fuse breaker FS4 for reg.-air fan (auxiliary contacts)
- thermostats ST1 & ST2 (man reset) which indicates too
high temperature in the electric heater box.
The dehumidifier is prepared for external regulation by a
hygrostat. Therefore terminals for this connection is pla-
ced into the connection box placed behind the cover - in the
front plate of the cabinet. The terminals are 23 & 24.

In the E-box the terminals for power connection are placed
too (U,V,W,N,PE). If an electronic hygrostat is used
the power supply can be connected the terminals 20 & 21
= 230V, internal fused with 6A.
The terminals 23 & 24 are shunted at delivery. This shunt
is to be removed and the terminals for the hygrostat
connected.
when a connected hygrostat breaks, the reg.-air fan
will continue operating for further 5 minutes for coo-
ling the heating elements, and for finishing the reg.-
process (controlled by ST3).
The dehumidifier CR2000 is connected 400V, 3N+PE. Connection
to the terminals U,V,W,N,PE, placed into the internal E-box
in the front of the dehumidifier.
For connection of an external electronic hygrostat for 230V
power supply, the terminals 20 & 21 can be used (internal
fused with 6A).
Power consumption is 24,1 KW - external fuses 50A max.
The electronic thermostat, the selector switch and the neons
are placed in the cover of the E-box.
Further a circuit breaker 63A is placed in the front of the
dehumidifier, and switched off, power for all internal com-
ponents are broken (excl. terminals U,V,W).
The electronic thermostat is placed in the cover of the
E-box. BT1 regulates and indicates the reg.-air temperatu-
re and the set point. Set point should be 130C.
Display is indicating the chosen set point (in green) and
the actual temperature at the sensor (in red).
To change the set point, use the "arrow up" or "arrow down".
The dehumidifier should be installed indoor, placed on the
floor or some other horizontal basis. The backside can be
placed against the wall, the remaining three sides of the
cabinet should be surrounded by a free area of 1m for ser-
vice. For some installations shock absorbers should be
placed under the cabinet.

8.1 The reg.-air is taken from the outside of the room, and
the reg.-air outlet should lead back to the outside.
Placing at an outer wall makes this installation easy.
Size of ducts is Ø200 mm.
should be fitted with filter (the in-
stalled filter can be used).
should be made draining against the
outlet, to allow condensate to run free. If this is not
possible, drill an Ø4 hole on the lowest part of the
duct for drain. Damper Ø200 for adjusting the reg.-air
flow must be installed.
8.2 Dry air outlet can be connected Ø250mm ducts. A damper
Ø250 should be installed and if necessary, a silencer.
8.3 If ducts are needed for inlet main air, Ø250 duct can
be connected. At delivery the dehumidifier then should
be supplied with an Ø250 connection to replace the net-
frame (option).
In general ducts of the same size as placed on the
dehumidifier should be used - or bigger.
Sound silencers could be fitted on the air inlets and
outlets. This should be done in consideration of the
air fans sound data, the location of the air fans in
relation to the inlets and outlets as well as to the
required sound level in the room to which the canals
have been connected or where the dehumidifier is located,
respectively.
If the dehumidifier should be connected to another air
treatment system, the air pressure of this system will
influence the dehumidifier. You should then contact
your supplier before installation for advice.
It is strongly recommended to follow the steps mentioned be-
low.

9. COMMISSIONING CR2000.
NOTICE: Measuring of voltage and other work in the E-box must be
performed by people educated as electricians.
When the cover for the E-box is open, (ex. for operating the MCB by
hand) the power supply must be switched off at the internal safety
switch and at the external main switch.
Page 21
- check the voltage between the terminals U,V,W (=
400V), and between U,V,W and N (= 230V).
- is the ground cable connected, and in the right dimen-
sion ?
- is the hygrostat (if needed) correctly connected ?
- is the recommended damper installed in the dry air
duct ?
- is the recommended damper installed in the reg.air
outlet duct ?
- is the reg.air outlet ducts installed draining away
from the dehumidifier - to allow condensed water to
leave the duct ?
Adjust the following positions of the dampers:
- damper in the dry air duct : 50% closed
- damper in the reg.air outlet : fully open
FS3,FS4,FS5,FS6,FS7 and the safety switch QS1 should be
switched on.
- switch on the selector switch SA1 (pos. "MAN" for con-
tinuous operation, pos. "AUTO" for automatic operation
by means of a hygrostat).
When the selector switch is switched on the process air
fan, reg.air fan, gear motor/rotor will be operating -
only the electric heater is not switched on.
If the dehumidifier does not start, it could have
the following reasons:
- phase rupture/phase sequence relay (P2) has two neons,
a green one and a yellow one. The green neon alight
indicates that the necessary 3 phases to the dehumidifier
are active.
- the yellow neon alight indicates a correct phase sequence.
Consequently, both neons must be alight in order for relay
P2 to pull.
- at start-up it might often happen that the yellow neon
does not light up, and as a consequence the dehumidifier
does not start, a fact which indicates an incorrect phase
sequence. Two cables in the power supply to the dehumidi-
fier should be exchanged.
- switch off the external main breaker and exchange two
of the phases (e.g. cables for U and V).
- Switch on the external main breaker, and the yellow neon
of P2 should light up and the dehumidifier should start up.
- alternatively, it might be that the external hygrostat
has broken (the selector switch in pos. "AUTO"). Adjust
the hygrostat to a low value, e.g. 20 %rH, and the
dehumidifier should start up.
a) Checking the electric installation before starting the
dehumidifier by switching the safety switch and the se-
lector switch.
b) Checking the connected duct system.
c) Suggested damper positions at commissioning.
d) Start up the dehumidifier by switching the MCB s in two
steps.
e) If the dehumidifier starts up as described above, then
go to f).
Page 22
- adjust the process air flow for the nominal 2000 m3/h
using a suitable instrument (Pitot pipe/thermo anemome-
ter or similar) - and adjusting on the damper
- adjust in the same way the reg.air flow to the nominal
600 m3/h.
Now all components must be operating.
- follow the raise in the temperature on the display of
BT1 (in the front of the dehumidifier)
- do the final adjustment of the reg.air flow on the dam-
per in the reg.air outlet duct, until the right va-
lue is indicated in the display.
The correct value is 130C at 20C inlet temp., 125C at
15C inlet temp....
- if the correct temperature is not reached it should
indicate that the reg.air flow is to big. Close the
damper until the correct value is shown in the dis-
play without BT1 switching the relay SSR-relays (check
neons on the relays)
- if the correct temperature is reached and the neon on
the SSR relays is only illuminated in short intervals,
it indicates that the reg.air flow is too small.
Open the damper until the neons are more or less
constantly illuminated.
With the electrical settings and air flows adjusted, the
dehumidifier will then operate automatically by means of
the internal control- and safety functions - controlled
by an external hygrostat.
Dehumidifier CR2000 only needs a minimum of maintenance.
All components are service free, which means no lubrication
or adjustment.
The maintenance work is limited to the following:
- check, or replace the filters for process and reg.air
- check, or replace the filter for the fan for the E-Box
- check that the rotor is rotating during operation of
the dehumidifier (visible through the inspection window
in the cabinet).
- check the 2 neons, HL1 & HL2. The green one must be illu-
minated during operation (HL1), the red one must not be
illuminated (HL2).
- check the thermostat BT1, the display should indicate
a reg.air temperature of 120-130C.
- check that the fans are operating
f) Now the dehumidifier is operating and the air flows
should be adjusted.
g) Finally the MCB`S for the electric heaters has to be
switched on (FS1,FS2).
Each month:
10. MAINTENANCE.
Page 23
Further to the work of each month, we will recommend the
following checks:
- check the wear on the rotor gaskets, especially the ga-
sket placed on the circumference of the rotor. The red
side of the gasket is Teflon, and this must be intact
all over the surface.
- check/repair evtl. inside cabinet corrosion
- check the drive belts for the rotor
- check the internal flexible hoses
- check that the insulation of cables are intact, no mecha-
nical or heat damages
- check that the insulation on the electric heaters are
intact
- check in the E-box that all cables are well fixed, all
MCB`s are switched on, all components are intact
- make a test of the functions of all electric components,
ex. by following "9. commissioning CR2000".
- check the fans according to the enclosed manual page 28
11.1 If the green neon is not illuminated, check the power
supply for the dehumidifier (external fuses).
Check the safety switch QS1 and the selector switch
SA1.
Check the green neon itself.
11.2 If the dehumidifier is not operating even that the green
neon is on, it is probably the external hygrostat
which has broken. This is a normal situation when the
desired humidity is obtained.
To check: adjust the hygrostat for 20 %RH, and the
dehumidifier should start-up.
(only when selector switch is in pos. "AUTO").
Adjust again for desired humidity.
11.3 If the red neon HL2 is on, one or more of the thermal re-
lays (for motors) might have switched off.
Alternatively the MCB FS4 or the thermostats ST1, ST2
(man reset) for the electric heater has broken.
11.4 All electric components are protected by a fuse brea-
ker, and will break at overload or at a short-circuit.
11.5 If the desired humidity is not obtained, the problem
can be the dehumidifier - or the other parts in the
total installation ( room tightness, hygrostat...).
- rotation of rotor ?
- reg.-temperature =120 - 130C ?
- neons on SSR relays
If the rotor does not turn during operation, the gear-
tor probably is stopped, or the drive belts have broken
Once a year:
To verify this, check:
11. TROUBLE SHOOTING.
Page 24
- if the temperature is 120-130C (=OK) but the neons in
the SSR relays are only illuminated in short periods,
this indicates a too small reg.air flow.
Check the reg.air inlet filter and the position of the
reg.air outlet damper.
If the filter is clean, the damper must be opened until
correct temperature and correct function of the SSR re-
lays.
Before opening the dehumidifier, make sure that the
electric power is switched off on the main switch.
Further the safety switch QS1 should be switched off.
Notice that there is still power on the terminals U,
V, W when the safety switch is off.
- all electric components (contactors, fuse breakers,
thermal relays) are placed in the E-box behind the
cover in the front side, and are available for servi-
ce/replacement when the cover is removed.
- remaining electric components (fan motors, gea rmotor,
heating elements, ST3) are available when the big co-
ver on the outer side of the cabinet is removed.
If a motor has been electric disconnected, the direc-
tion of rotation should be checked after re-connection,
and two of the cables should be exchanged if direction
is wrong.
The two drive belts should be removed from the pulley,
and after electric disconnection the gear motor can
be removed and exchanged.
Check the direction of the rotor : looking from the
outside on the surface of the rotor, it must move
downwards.
All electric heaters are placed in the front of the
heater section. Disconnect the wiring, and unscrew
the plate. The plate and all heaters can then be drawn
out of the heating section.
(see drawing R1891 page 26)
- the duct connection to the reg.-air fan is to be remo-
ved to give the necessary space for removing the
dividing plate (back).
- the dividing plate to the left (back) is to be removed
by unscrewing the 5 pcs inbus screws for the distance-
bolts, the 2 pcs inbus screws into the bottom frame,
and the two inbus screws in the rotor shafts.

- the rotor has to be sufficiently supported underneath,
when removing the dividing plate to the left.
- the rotor shafts are screwed into the rotor, and
should not be removed. The shafts has to be drawn out
of the ball bearings which are fixed on the dividing
plates.
- the rotor gaskets are made of silicone rubber with a
outside layer of teflon. The teflon should face against
the rotor and the departing plates.
When replacing the gaskets the rotor do not need to be
removed. The new gasket is placed on the rotor and
slightly fixed with the 3-parted expansion ring. The
rotor is then turned and the gasket pressed against
the departing plates until only half of the gasket
is on the rotor. The expansion ring then fasten.
In the top of the cabinet, 4 pcs lift screws are placed.
They must be used for lifting the dehumidifier.
A truck can be used too, carrying underneath the cabinet.
The sound level is measured according to EN292-2, annex A:
" if the working place is not specified or cannot be spe-
cified, the noise level should be measured in a distance
of 1m from the unit, and in a distance of 1,6m from the
floor or the frame".
The dehumidifier is during the measuring of the noise level
placed with the top cover 1m above the floor. Ducts for reg.-
air is installed and led out of the room, and 2m dry air
duct Ø250 is connected to the dehumidifier.
The noise level is then measured 1m outside the front of
the cabinet (outside the big cabinet cover), and 1,6m above
the floor.
The noise level is : 63 dB(A).
