The moist air outlet pipe must be fed away from the dehumidifier
with a slight downward gradient in order to avoid condensate run-
ning into the appliance or impairing the flow of air. If a rising air pipe
has to be used, then a low point with a drain must be specifically
manufactured (via a siphon, if the dehumidifier is located in the room
being dehumidified). The pipe should be insulated.
Recommended measures to be taken before starting up
1. Have the air supply and exhaust ducts been cleaned? Are the air
inlet and outlet compartments at the rotor clean?
2. Are any louvered dampers that may exist in the connecting ducts
open and have the transport sealing caps been removed?
3. Check that the throttle flaps are seated correctly and work perfectly.
4. Check that the transport locks have been removed from the fan mo-
tor.
5. Turn the fan by hand, in order to make sure that it turns freely. Ensu-
re that there are no foreign bodies in the fan housing.
6. Check the tension and adjustment of the belts and correct them if
necessary.
7. Are all seals tightly seated?
8. Are the electrical cables correctly connected to the dehumidifier
(see circuit diagram)?
9. Is mains voltage present and are the motor protection breakers
switched on?
10. Check the direction of rotation of the motor. The electric motors in
the dehumidifier are connected in the factory such that the inten-
ded direction of rotation of the fan motors is ensured if the direc-
tion of rotation of the rotor is correct.
If the ‘Check phases’ indicator lamp lights up, correct the direction of
rotation by exchanging two phases of the mains connection or make
sure that all three phases are live!
11. Are the service doors and side panels tightly closed?
12. The dehumidifier can be put into operation once all inspections
have been completed. After that, measure the voltage and current
consumption and compare them to the data on the rating plate.
Check and adjust the air quantities and pressures.
03. Appliance description
Trotec dehumidifiers work according to the adsorption principle and
are used for solving drying tasks in process technology, in air conditio-
ning technology and for the dehumidification of production areas and
warehouses in which products and installations require particularly
low humidity.
The adsorption technique permits lower dew points and more reliable
dehumidification at low temperatures than is possible with cooling de-
humidifiers for physical reasons. In addition, Trotec dehumidifiers are
considerably more economical to use in such conditions.
The dehumidifiers are fully equipped with rotor, fans, drive motor, hea-
ter for regeneration and electrical equipment.
The moisture is adsorbed from the air using the silica gel rotor.
Operating principle
The dehumidifier works continuously with two air streams (about 3:1).
The larger process air stream is dehumidified in the slowly rotating si-
lica gel rotor (= adsorption), whilst the smaller regeneration air stream
is heated, thus expelling the adsorbed water from the silica gel (=
desorption).
The dehumidifier is a continuously working appliance with integrated heat recovery and can achieve very low dew points. The heat energy of the hot
regeneration air zone is transported by the rotating rotor into the flushing zone; the rotor cools down and simultaneously pre-heats the entering rege-
neration air. The result is process air that has been less heated and a lower dew point.
