desiccant dehumidifier TTR 160 / TTR 250
Transport and installation
To make the device easier to transport, it is fitted with a
carrying handle.
Note
If you store or transport the device improperly, the
device may be damaged.
Note the information regarding transport and storage of
the device.
Note
Device may be damaged by vibration!
Excessive vibrations can result in damage to the
device.
Therefore, protect it against excessive vibrations, e.g.
abrupt positioning or dropping, during transport.
Always protect the device from slipping during
transport.
Only lift or carry the device at the provided fixtures.
Positioning
•
Inside the room to be dehumidified:
– The device works in recirculation mode, the
regeneration air must be fed from outside and the
regeneration exhaust air must be led outside.
•
Outside the room to be dehumidified:
– The device can be connected in either recirculation or
ventilation mode. A connection of the dry air to the
room to be dehumidified must be established.
Storage
When the device is not being used, observe the following
storage conditions:
•
dry and protected from frost and heat
•
in an upright position where it is protected from dust and
direct sunlight
•
with a cover to protect it from invasive dust, if necessary
•
When not in use, always disconnect the device from the
power supply.
•
Up to 4 devices may be stacked on top of one another to
save space.
•
Secure stacks against toppling over.
Assembly and installation
•
The pipes or hoses used must be designed for the
available static compression of the fans. The air hoses
should preferably be laid in a straight line and at full
length.
•
The regeneration exhaust air line must be laid with a slight
decline so that possibly accumulating condensate cannot
flow back into the device or obstruct the air flow. If an
incline cannot be avoided, it is necessary to establish a
condensate drain. As preventive action, the exhaust air
pipe may be insulated.
•
To prevent an immediate neutralization with the moist
exhaust air, the humid air outlet should be guided away
with a minimum distance of approx. 1 m in case of direct-
intake devices.
Scope of delivery
The scope of delivery of the device contains:
•
1 x Dehumidifier
•
1 x Connection cable
•
1 x Instructions
There are further accessories optionally available, which can be
obtained from the Trotec customer service.
Default settings
Generally, air conditioning units are equipped with one or more
fans, which must be overdimensioned accordingly to overcome
resistances caused by pipes or appliances. Usually, their speed
cannot be adjusted. In order to set the air quantities required for
the application, a hydraulic compensation must be carried out
by means of throttle valves installed in front of or behind the
fan.
For heating the regeneration air, the device is equipped with a
heater battery generating heat by means of ceramic PTC
semiconductor elements. The latter have a maximum surface
temperature of approx. 240 °C, which they try to maintain. The
temperature-dependent resistance, which rises rapidly as of a
certain value (Curie temperature) when the heat reduction
decreases, causes self-regulating effects of the heating current
consumption, i.e. when the air temperature rises and/or the air
volume decreases, the current consumption is reduced (and
vice versa). Furthermore, a destruction caused by overheating,
for instance due to a lack of regeneration air, can be virtually
ruled out.
In order to reach a preferably
low outlet humidity level
with a
minimum dry air volume or to achieve the
highest
dehumidification performance
with a maximum dry air
volume, it is important to set the regeneration air volume
correctly. The air volume must be adjusted until the value
specified as
optimum heating current
is indicated on the
ammeter.
For all other applications with low requirements regarding the
dehumidification performance and dry air volume, the
regeneration air volume may be decreased until the value
specified as
minimum heating current
is indicated on the
ammeter. This allows you to achieve very good dehumidification
results at minimum energy input.
