Information about the device
Device description
The dehumidifiers of the DH series uses the principle of
condensation to automatically dehumidify rooms.
The fan sucks damp room air through the air inlet, the
evaporator and the condenser located behind it. The air is
cooled at the cold evaporator until it is below the dew point.
Water vapour contained in the room air precipitates on the
evaporator fins as condensation or rime. The dehumidified,
cooled air is rewarmed at the condenser and blown out at a
temperature of approx. 5°C above room temperature.
The drier air, thus conditioned, is mixed with the room air again
or guided to other areas via an air duct system. The humidity in
the room where the device is positioned – or in the
corresponding area – is reduced as air constantly circulates
through the device.
The condensate is fed through a pressure-resistant pipe
connection and out of the device by means of a condensation
drain hose. For the collection you can for instance place a
sufficiently dimensioned collection container beside the device.
Alternatively, the condensate can be discharged using the
installed condensate pump.
The device has a control panel for operating and controlling the
functions. Moreover, the device is fitted with an energy meter as
standard.
The device can reduce the relative humidity of a room to approx.
30%.
Because of the heat radiation generated during operation, the
room temperature may rise slightly.

Notes regarding the dehumidification performance
The dehumidification performance depends on:
• the layout of the room
• the room temperature
• the relative humidity
The higher the room temperature and relative humidity, the
greater the dehumidification performance.
For use in living rooms, a relative humidity of approx. 50 to
60% is sufficient. In storage facilities and archives, the
humidity should not exceed approx. 50%.

EN 7
condenser dryer DH 160 / DH 310
Water discharge
The water condensed on the heat exchanger must be
discharged. This can be done in two ways:
Option1: via the condensate drain hose connection
Option2: via the pump drain hose connection
The industrial dryer is equipped with hose connections for hoses
with an inner diameter of 16mm.
1. Connect a suitable hose to the condensate drain hose
connection(6) or to the pump drain hose connection(7).
Note
Please note that one hose connection is fitted with a
plug.
If necessary, remove the plug from the hose
connection where you want to connect the hose.

2. Use the plug to close the hose connection that is not used.
Air routing
The dry air can be transported to areas with a high relative
humidity level e.g. via air ducts. A correct air distribution is
essential here to achieve a controlled humidity value in the
respective areas.
Note
Air ducts and other elements may only be connected
by a specialist company for ventilation, cooling and
air-conditioning.
Note
The industrial dryer and the air ducts operate at
ordinary temperatures. Should they come into contact
with unheated rooms, e.g. because the air ducts are
routed through unheated basements or attics, they
must be insulated.
Discharge of dry air
To achieve a more even air distribution, it is often necessary to
install appropriate air ducts. Observe the device's technical data
(air volumes and pressures) when dimensioning air ducts and,
if required, other elements (such as grilles or heaters).
Please note the following when installing an air routing system:
• If an air duct is mounted at the air inlet, the duct must
cover the entire cross section.
• All devices are equipped with a connecting flange at the air
outlet as standard.
• The connecting flange and/or air filter can be ordered from
Trotec.
• Remove any cover plate or grille possibly mounted before
connecting the air ducts.
• After having installed the air routing system, including the
grille (if any), check the air flow rate. The air flow rate
must correspond to the air flow rate (±10%) specified in
the device's technical data and should be adjusted
correspondingly via the main valve. If the air flow rate
deviates too strongly, the dehumidification performance
will not be achieved.
Electrical installation (voltage supply)
Warning of electrical voltage
Electrical work on the industrial dryer may only be
carried out by a qualified electrician.
The electrical installation must meet the requirements
of the latest VDE standard (German Association for
Electrical, Electronic & Information Technologies) and
local provisions.
The voltage supply must be protected by fuses and
circuit breakers suitable for the motor. A disconnector
must be installed next to the device.
All devices must be properly grounded. We recommend
that you install a residual current device (RCD).
Note
Only if the following voltage and frequency limits are
complied with, can the specified performance values
be achieved:
Devices with one phase: Nominal voltage
230V±10%
Devices with three phases: Nominal voltage
400V±10%
Nominal frequency 50Hz ±5%
These voltages must be applied when the dehumidifier
is operated at full power.
Note
All devices are equipped with a phase failure relay.
If one phase is missing or if there is no clockwise
rotating field, the indicator light at the relay will be off
and the industrial dryer will not start.
