Product description

The dehumidifier is designed to meet the
requirements of IEC protective class IP 44.

Casing

The casing is fabricated from stainless steel
2333. The top of the dehumidifier has a top
panel that can be removed for service access to
the electrical components. The front panel of the
dehumidifier can be removed for service access
to all mechanical parts. All duct connections to
the dehumidifier are designed for connections to
standard size spiral ducts.

Rotor

The dehumidifier has a drying rotor fabricated
from a desiccant material. The rotor has a matrix
of corrugated and flat heat resistant sheets which
houses the Silica Gel desiccant agent. This
matrix creates a large number of axial flutes
through the rotor, which together builds up an
immense surface area for moisture adsorption in
a small volume. The rotor is manufactured and
processed to be able to withstand moisture satu-
rated air without being damaged. This means the
rotor can be used in conjunction with a pre-cool-
ing coil. Further more the rotor will not be dam-
aged even if the fan or the heater for reactivation
should fail during operation. The rotor is incom-
bustible and non flammable.

Rotor drive system

The slow rotation of the rotor is achieved by an
electrical gear motor and a belt drive. The belt
sits on the outer rim of the rotor and is driven
by a pulley on the drive motor. A belt tension
device keeps the belt in place and maintains
tension to prevent belt slip. Correct operation of
the drive system, and direction of rotation can be
checked by opening the front panel.

Rotor bearings

The centre hub of the rotor is equipped with ball
bearings. The rotor shaft is made from stainless
steel.
Subject to change without notice

Filters

The dehumidifier has two separate filters. One
in the process air inlet and one in the reactiva-
tion air inlet.
Fans for process- and reactiva-
tion air
The fans are direct driven radial fans with three
phase standard motor class IP 54, ISO F. The
fans are accessible for service after removing the
panels.

Heater for reactivation air

The electric reactivation heater is divided into 2
heater banks. As an option the dehumidifier can
be delivered with a heater for steam, hot water
or LPG.

Electrical panel

The electrical panel is located in a separate com-
partment at the top of the dehumidifier. Switches
and indications for operation are mounted at the
front of the dehumidifier.

Operation options

Using the operation switch on the dehumidifier,
different running options can be selected:
0 Dehumidifier not in operation.
MAN Dehumidifier in continuous
operation.
AUTO Automatic operation by remote
humidistat, or other external
start/stop signal.
Inside the unit, there is a switch marked S3, that
allows continuous operation of the dry air fan.
When the machine is turned off using the opera-
tion switch, the wet air fan is in operation for as
long as it takes to cool off the heater element.
Never use the main powerswitch to stop the
machine, as it could overheat!
