1. PRINCIPLE OF OPERATION.
The dehumidifier removes water from an airflow through, and he
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.
ch
no
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 process air (moist air inlet) passes through the drying
part, and leaves the dehumidifier as dry air
- the reg.-air passes, after heating, through the 90 degree
regeneration part of the rotor, and the adsorbed water will
be removed.
en
t te
The two air flows are fixed and the rotor turns - this gives an
automatic process of simultaneous water adsorption and water
extraction.
CAPACITY DIAGRAM R618:
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.
Example: (shown in the diagram)
- inlet air conditions 20°C, 60 %RH, gives water content 8,7
g/kg
- the diagram shows then dry air condition of X= 3,2 g/kg
8,7 - 3,2
- removed per kg air is then:
= 5,5 g/kg
im
Capacity CR450 at this condition:
Dry air flow is nominal 450 m3/h= (x 1,2)
= 540 kg/h
Capacity, removed water per hour - 540 x 5,5 = 2970 g/h
= 71 kg/24h
ud
at 400V.
ba
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 42°C.

2. APPLICATIONS.
ch
no
Dehumidifiers in the CR range is 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 hygroscopic
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 supplied
as options.
en
t te
The air to the dehumidifier should be free from solvents or
other explosive components, and should be free from pollution
from solid particles and chemical substances ( ex. Acids,
bases...).
Oil vapours, exhaust gases from Diesel engines in the air will
seriously damage the rotor.
For air to the dehumidifier the following limit values
must be respected :
- max. humidity
- max. Temperature
- max./min. pressure
100 96RH
35 °C
ambient +/- 500Pa
ba
ud
im
The CR range is for indoor, stationary installations.
Should not be placed in rooms with possibility for free water
on the cabinet.

7.2 REGULATION BY HYGROSTAT.
en
t te
The dehumidifier is prepared for external regulation by a
hygrostat.
The black plug for hygrostat connection is internal connected
the terminals 200X6.
Terminals in the black plug:
1,2 for hygrostat
3,4 for 230V connection for external hygrostat *) power supply
*) COTES Electronic humidity controllers:
DA20, DH24 or DCC.
im
NB: when a connected hygrostat breaks, the reg.-air fan
will continue operating for a few minutes for cooling
the heating elements, and for finishing the reg.-process
(controlled by ST3).
7.3 ELECTRIC CONNECTION, CR450.

8. INSTALLATION.
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 lm for service
+ lm above the cabinet.
ch
no
CONNECTION OF DUCTS :
8.1 The reg.-air is taken from the outside of the room, and
the reg.-air outlet should lead back to the outside.
Therefore the dehumidifier is placed on an outer wall
through which these connections are possible.
Size of ducts is 0100 mm.
en
t te
Reg.-air inlet should be fitted with filter (the installed
filter can be used)
Reg.-air outlet should be made draining against the outlet,
to allow condensate to run free. If this is not possible,
drill an 04 hole on the lowest part of the duct for drain.
For the adjusting of the reg.air flow a damper DN100 must
be installed.
8.2 Dry air outlet can be connected DN 160 mm ducts. A damper
DN 160 should be installed and if necessary, a silencer.
8.3 If ducts are needed for inlet main air, DN 160 duct can
Be connected. At delivery the dehumidifier then should
be supplied with a DN 160 connection instead of the netframe (option).
im
In general ducts of the same size as placed on the dehumidifier
should be used - or bigger with regards to the pressure loss.
NB: If the dehumidifier should be connected to another air
ud
treatment system, the air pressure of this system will
influence the dehumidifier. You should then contact
your supplier before installation for advice.
ba
Silencers can 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.

9. COMMISIONING CR450.
ch
no
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 as
described below) the power supply to the dehumidifier must be switched of at
the internal safety switch and at the external main switch.
It is strongly recommended to follow the steps mentioned below.
a) Checking the electric installation before starting the
dehumidifier by switching the safety switch and the selector switch:
- measuring the voltage between Ll,L2,L3 (=400V), and
between L1,N - L2,N - L3,N (= 230V).
- is the ground cable connected?
- is the hygrostat correctly connected?
b) Checking the connected duct system.
en
t te
- is the recommended damper installed in the dry air
duct?
- is the recommended damper installed in the reg.air
outlet duct ?
- is the reg.outlet duct installed draining from the
dehumidifier ? - or if not possible, is then a hole
DN4 drilled at the lowest point of the outlet duct?
c) Damper positions in start-up procedure.
Adjust the following positions on the dampers:
- damper in dry air duct, SO% closed
- damper in reg.air duct fully open
d) Start up the dehumidifier by switching the MCB's :
im
- close 10F1,42F1,42F3 (MCB)
- switch on the safety switch QS1
- switch on the selector switch SA1 (pos "MAN" for constant
operation, pos "AUTO" for controlling by connected
hygrostat)
ud
When the selector switch is in pos "MAN" or "AUTO" the dehumidifier now is operating on process air fan, reg.air fan,
rotor - only the electric heater is not switched on.
e) If the dehumidifier starts up as described above, then go to f).
ba
If the dehumidifier does not start, it could have
the following reasons:
- the phase rupture/phase sequence relay 100K3 has two pilot lamps,
a green one and a yellow one. The green neon alight indicates
that the necessary 3 phases to the dehumidifier are active.
log
y
Page 13
ch
no
- the yellow neon alight indicates a correct phase sequence.
Consequently, both pilot lamps must be alight in order for relay
100K3 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 dehumidifier should be
exchanged.
- Switch off the external main breaker and exchange two of the
phases (e.g. cables for Ll and L2).
- Switch on the external main breaker, and the yellow neon of
100K3 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.
f) Now the dehumidifier is operating, and the air flow must be adjusted.
en
t te
- adjust the process air flow for the nominal 450 m3/h
using a suitable instrument (Pitot pipe/micro manometer,
thermo anemometer or similar)
g) Finally the MCB (FS1) for the electric heater has to be switched on.
Adjust the reg.air flow for an Amp. Indication of 6,0A on
150P1, readjust after 5 min. of operation.
ba
ud
im
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.

10. MAINTENANCE.
Dehumidifier CR450 only needs a minimum of maintenance.
All components are service free, which means no lubrication
or adjustment.
We recommend the following:
Maintenance, every month:
Maintenance, once a year:
ch
no
- check the two filters, replace if necessary
- check the rotation of the rotor. The rotor is visible
when the grey plug in the cabinet top cover is removed.
- check the pilot lamps. The green one HI1 must always be illuminated during operation, the red one H1.2 indicates thermal
fault and must not be illuminated.
- check the Am-meter (150P1), must indicate 6A
ba
ud
im
en
t te
- at first check the positions mentioned for the monthly
maintenance
- clean the cabinet inside and outside if necessary
- check all gaskets for wear and tear, position
- check the drive belts for sufficient extension
- check all cables for intact insulation and fixation
- check the function of the electric components
- check the MCB, must be switched on
evt. check the capacity of the dehumidifier
log
y
Page 15
11. TROUBLE SHOOTING.
ch
no
11.1 If the green pilot lamp is not illuminated, it can have
the following reasons:
- Relay 100K3 might have broken for incorrect phase sequence
or a missing phase in the power supply
- The MCB 10F1,42F1,42F3 might have opened
- Check the pilot lamp itself
11.2 If the dehumidifier is not operating even if 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.
Adjust again for desired humidity.
en
t te
11.3 If the red neon is on, the thermal relays 100F1, 101F1
might have opened.
Resetting by pushing the blue button on the relays.
The thermostat ST1 with manual reset might have broken.
Push the black button on the thermostat and check at the same
time that the reg.air fan is operating.
11.4 All electric components are protected by a MCB,
and could be switched-off at overload or by 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...).
im
To verify this, check:
- rotation of rotor ?
- Am.Meter (150P1)indicating 6A?
If the rotor do not turn during operation, the gear motor
probably is stopped.
ba
ud
Observations on the Am-meter (150P1).
The indication must be GA for correct adjusted reg.air flow.
If the indication is 0 A (zero) the heater is not on.
Check the heaters and the contactor 200K3.
