Information about the device
Device description
The device is designed to be a mobile solution for room frost
protection, comfort heating, pest control, surface
decontamination, HEPA filter operation and room
decontamination.
Each device comes equipped with the respective application
programmes which can be adjusted as needed. For example,
you can adapt the type of treatment, the duration and the target
temperature.
Variable equipment option: Depending on the application
purpose, you can use the system component combinations with
DualDecon blowing-out tower (standard) or TACXT18 /
TACXT27 with DualHeat blowing-out tower.

EN 7
vertical heater TAC XT 18 / TAC XT 27
Functioning principle
The air is taken in by the fan via the air inlet with air filter and
will be heated by means of the multi-stage electric heating.
Optionally, the heated air can be purified with a HEPA filter.
Afterwards, the air will be evenly distributed throughout the
room via the blowing-out tower. The device can also be
connected to a ventilation system using an attachment hood on
a hose connection.
For the purpose of pest control, no HEPA filter should be
installed on the device, so as to allow for a maximum air flow
rate.
If the device is operated with a ventilation system, the use of an
external thermostat (HG 125 - 6.100.002.042) is required.
The blowing-out temperature (identical to the supply
temperature) can be set up to maximally95°C. The
temperature sensors at the air inlet and the air outlet regulate
the adjusted room temperature within a narrow range as they
activate or disactivate additional individual heating elements.

Start-up
When positioning the device, observe the minimum distance
from walls or other objects as described in the chapter
Technical annex.
A
B
C
C
D
• Before restarting the device, check the condition of the
power cables. If there are doubts as to their sound
condition, contact the customer service.
• The device may only be used in environments with no
excessive formation of dust.
• Set the device up in an upright and stable position.
• Position the device on even, stable and heat-insensitive
ground in a way to prevent it from tipping over.
• When setting up the device, ensure a sufficient distance
for air inlet and outlet as well as for operation (see
Technical data).
• Do not create tripping hazards when laying the power
cables or other electric cables, especially when positioning
the device in the middle of the room. Use cable bridges.
• Make sure that extension cables are completely unrolled.
• Make sure that no curtains or other objects interfere with
the air flow.
• Make sure that the device cannot come into contact with
moisture or water.
Inserting the air filter
Note
Do not operate the device without an air filter inserted
into the air inlet!
Without the air filter, the inside of the device will be
heavily contaminated. This could reduce the
performance and result in damage to the device.
• Make sure that the air filter is installed before switching
the device on.
Attaching a flowstop shutter
The optional flowstop shutters can be attached to one of the
four insides of the tower. This prevents up to three sides of the
tower from discharging air, e.g. if discharged air is not desired
or not required on the respective side(s).
Connecting the power cable
• The device is provided with two power cables. If you only
connect one power cable to the an power connection 1(5),
the TACXT18 only supplies 9kW and the TACXT27
supplies 18kW. Connection of the second power cable to
power connection 2 (4), the devices will supply their
maximum power. The device can be operated with a
generator with sufficient capacity. Take into consideration
that the heat output of the device is controlled, so that the
generator connected has to adapt to the control. Ensure in
advance whether the generator complies with the power
supply of the device.

Recommendations for filter regeneration:
Under normal environmental conditions, such as those
prevailing in offices, schools, kindergartens or public buildings,
it is sufficient to regenerate the filter once a week. If the air
cleaner is used in cool areas with high humidity levels, e.g. in
slaughterhouses or in the food industry in general, we
recommend to regenerate the filter daily.
Note
During decontamination, an odour may be produced,
which is harmless.
Note
The software monitors whether filter regeneration is
carried out regularly. After 50hours of air cleaning
operation, a message appears with the option of
starting filter regeneration immediately. If filter
regeneration is not started at this time, the number of
days by which filter regeneration is overdue will be
displayed each time the device is switched on.
Surface decontamination
Surface decontamination allows to thermally decontaminate a
