Caution
Only use residual current devices sensitive to all types
of current (type B or B+). The integrated EMC filters
can lead to instantaneously tripped RCDs.
Use residual current devices with a minimum triggering
level of > 300 mA and delayed tripping (type K).
Note
Do not operate the device without an inserted air filter!
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 off the device.
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.
Design
The basic device consists of the following components:
• fans for air transport
• air filters behind every air inlet
• separate sectors for process air (to be dehumidified) and
regeneration air (humid exhaust air)
• purging sector for heat recovery
• 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
• Depending on the selected options further components are
possible (see Technical annex).
During dehumidification the desiccant wheel turns continuously
at a low speed (depending on the configuration 2 to 40 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.
Process air
The air to be dehumidified is sucked in by means of a fan. The
process air (4) flows through the desiccant wheel's
dehumidification sector (1).
In doing so, the contained moisture is withdrawn by the sorbent
(silica gel) and retained (desiccation). Due to physical processes
the temperature of the dry air (6) increases. Later the dried air
flows towards the dry air outlet.
