desiccant dehumidifier TTR 160 / TTR 250

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.

Note

Dirt accumulating inside the rotor can substantially
reduce the dehumidification performance or damage
the rotor beyond repair.
Supplying the system with contaminated air might
damage the rotor. Observe the information regarding

"Harmful influences on rotors"

.

Note

After a power failure the device will restart
automatically provided that it was not switched off in
the meantime. This behaviour is desired and necessary
to ensure operation with little supervision.

Behaviour in the event of an emergency

1. Switch the device off.
2. In an emergency, disconnect the device from the mains

feed-in: Hold onto the mains plug while pulling the power
cable out of the mains socket.

3. Do not reconnect a defective device to the mains.

Information about the device

General description

Dehumidifiers operating on the desiccant principle are used to
tackle drying tasks in the field of process engineering, air-
conditioning, on construction sites and for the dehumidification
of production and storage facilities, where a particularly low
humidity level is required over a broad temperature range.
The desiccation technique enables the safe and economic
operation even at low operating temperatures.
The desiccant dehumidifier works with a desiccant wheel
(rotor), which is composed of layers of smooth and corrugated
non-woven fabric with chemically bonded silica gel. Thus
created is a honeycomb structure with a large number of axial
air ducts with a large surface and direct connection to the inner
pore structure of the silica gel.
On account of the desiccant wheel's good mechanical and
physical properties no silica gel is discharged. It may be
supplied with saturated air with a relative humidity of up 
to 100 % but not with water drops. The rotor is incombustible.

Design

The general structure of a dehumidification unit is as follows:

fans for air transport

at least two different sectors for guiding the process air (to
be dehumidified) and the regeneration air (moist exhaust
air)

rotor desiccant wheel for the dehumidification with silica
gel

drive unit with gear motor, toothed belt pulley and toothed
belt

heater battery for heating regeneration air

During dehumidification the desiccant wheel turns continuously
at a low speed (depending on the configuration 3 to 30 rotations
per hour). Via the sectors the desiccant wheel is simultaneously
charged with the process and regeneration air so it can
constantly absorb and release moisture.
