Applicazioni
The dehumidifier ADS150÷300E is of the absorption type, with the rotor of desiccant and has been
designed to dehumidify air at atmospheric pressure. The dehumidifier can be used to dehumidify air at
relative humidity up to 100% and temperature from -30°C to +40°C.
The applications are many and cover all segments, but here are some examples:
Moisture control in manufacturing processes.
Drying temperature sensitive products.
Maintaining proper humidity levels in warehouses.
Corrosion protection of plants and in general of ferrous materials.
Moisture control in museums and libraries.
Drying after flooding of properties and buildings.
Improvement of environmental conditions occur anywhere excessive moisture.
Principle of operation
The dehumidifier works by using an air flow; a part of the
air consists of the air to be dehumidified, another part -
of minor flow - is instead used to regenerate the
dehumidification rotor. A fan inside the dehumidifier
creates two air flows that pass through the rotor in
opposite directions. The air to be dehumidified - also
called "process air", passes through the desiccant rotor
impregnated with silica gel. Silica gel is a highly
hygroscopic material that absorbs water vapor from the air. During the crossing of the rotor, the air
transfers its moisture content to the rotor itself. The dehumidified air is then sent to the production
room or to the dehumidifying process. The dehumidification process can take place between
temperatures between -30°C and +40°C. During the process the rotor rotates very slowly and is
equipped with a transmission system with reduction gear and belt. The so-called "regeneration air", is
used by the system to remove the absorbed moisture and take it outside: it is heated by a battery
inside the dehumidifier, up to about + 80°C and crosses the rotor in the opposite direction from the
process air and submits it to an inverse process, for which the rotor transfers its moisture content and
its initial absorbing capacity is restored. The regeneration air is expelled lukewarm and humid and must
be sent to the treated environment.

Product Description
The dehumidifier has been designed to meet the requirements of the degree of protection IP 54 of IEC.
Structure
The structure of the dehumidifier is made of steel and AluZink AISI_304 with simple panels. The top
panel can be removed for maintenance to electrical components and all internal mechanical parts. The
connections to the dehumidifier can be made with standard spiral ducts.
Rotor
The dehumidifier has a rotor made with desiccant material. The rotor has a honeycomb structure made
of corrugated and heat-resistant sheets that contain the silica gel desiccant, which creates a large
number of axial fluid threads and at the same time a high absorption surface in a small volume.
Furthermore, the rotor will not be damaged if the process fan stops due to an anomaly during
operation. The rotor is non-combustible and non-flammable.
Transmission system
A belt drive system controls the movement of the rotor. The belt exerts its pull on the outer edge of
the rotor and is driven by a pulley on the engine gearbox. A special device maintains the correct belt
tension to prevent slippage of the belt itself. The correct direction of rotation and the transmission can
be verified by opening the front panel.
Bearings
The rotor is provided with ball bearings. The rotor shaft is stainless steel.
Filter
The dehumidifier has one filter (G2), on the input process and regeneration air.
Ventilatore per l'aria di processo e rigenerazione
The fan is directly coupled to a single phase motor class IP55, ISO F, Class B. They are accessible for
maintenance by removing the inspectable upper panel.
Battery heating reactivation rotor
The battery power of regeneration is PTC (Positive Temperature Control), which eliminates the risk of
overheating and provides modulating control 50-100% of the performance of the dehumidifier, acting
on the air flow rate of reactivation.
Electrical panel
The electrical panel is located inside the unit. Switches and indicators are functioning outside of the
dehumidifier.

Ability to operate
The operation selector placed outside of the dehumidifier allows the following modes of operation:
MAN dehumidifier in operation in continuous
AUTO dehumidifier controlled by a
humidistat or by an external signal
When the dehumidifier is turned off, wait at least 15 minutes before accessing the inside.
