Description of the unit
The units are designed for
universal and problem-free
dehumidification.
They can be installed at numerous
locations due to their compact size.
The units operate according to
the condensation principle and
feature a hermetically sealed
refrigeration system, low noise and
maintenance circulating fan and
connecting cable with plug.
The fully automatic electronic
control with hot gas defrosting,
integrated hygrostat and
connections for local condensate
drain ensure trouble-free,
continuous operation.
The units are reliable and easy
to use and comply with the
fundamental health and safety
requirements of the pertinent EU
regulations.
The units are used wherever it
ist important to have dry rooms
and consequential damage (e.g.
through mould formation) is to be
avoided.
The units are also used for the
dehumidification of:
■
Private swimming pools
■
Wellness areas
■
Whirlpool areas
■
Sports studios
■
Store rooms/archives
■
Museums

Operation
The units can be switched on
and off with the operating switch
and the integrated hygrostat. In
dehumidification mode, the green
“dehumidification”
pilot light at
the top of the front panel lights
up.
The recirculation fan sucks in the
humid room air via suction openes
integrated at the bottom of the
front panel.
This is transported via a filter,
evaporator and condenser.
Heat is extracted from the room air
on the cold
evaporator
and cooled
to below the dew point.
The water vapour contained in the
room air deposits as condensate or
frost on the evaporator tubes.
The cooled and dehumidified air is
reheated on the
condenser
(heat
exchanger) and blown back into
the room via the side outlet grilles
with a slight rise of temperature
of about 5°C above room
temperature.
The conditioned drier air
continuously mixes with the room
air.
Due to the constant circulation of
the room air through the unit, the
relative humidity in the room is
gradually reduced to the required
humidity (% relative humidity).
The hygrostat is set at the factory
to 50% relative humidity.
Depending on the room air
temperature and relative humidity
the condensed water drips
constantly or only during the
defrost phase into the condensate
trap and subsequently via the
integrated drain connection
into the condensate drain to be
provided locally.
Safety circuit:
If the temperature at the
condenser should exceed 55°C
(e.g. due to fan failure or clogged
suction filter), the unit stops
automatically to avoid being
overloaded.
The compressor restarts
automatically after 45 minutes.
NOTE
in normal operation, the
compressor always starts with
a delay of about 45 seconds.
