Product description
The dehumidifier is designed to meet the requirements of the degree of protection IP54 of IEC.
Structure
The structure is made with pre-painted double-shell galvanized/AISI 304 steel panels (sandwich
type).The top panel can be removed for maintenance purpose. The connection to the dehumidifier can
be made with standard gimped channels.
Rotor
The ceramic matrix is combined with synthesized silica gel to form the most advanced dehumidifier rotor.
The ceramic matrix gives structural support for the thin layer of advanced silica gel. The synthesized
advanced silica gel is self-bonding to the ceramic matrix and to itself through the matrix, filing in all the
voids in the matrix and totally encapsulating the ceramic. Only the desiccant in contact with air-stream.
The advanced form of silica gel has an extremely high “affinity” for water vapor. It has an active surface
with numerous macro-pores of uniform size and shape. The many internal micro-pores quickly adsorb
humidity and are readily de-sorbed for convenient and continuous dehumidification. The synergistic
form of the desiccant and ceramic matrix allows for distinct advantages over both granular adsorbents
are impregnated desiccants. With the advanced silica gel rotor are no granules and no dusting. It stops
adsorbing moisture hen moisture is in equilibrium with the moisture in the passing or surrounding air-
stream. There are never any deliquescent problems associated with this system.
Furthermore, it can be coupled with a pre-cooling coil.
Drive system
A belt drive system controls the movement of the rotor. The strap exerts its traction on the outer edge
of the rotor and is driven by a pulley on the motor reducer. A special device maintains the correct belt
tension to prevent slippage of the belt. 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.
Filters
The dehumidifier has two filters (G4) separate: one on the input process air and the other one on the
input reactivation air. In option filters with different efficiency can be installed.
Fans for the process and regeneration air
The fans are directly coupled to a single-phase motor and/or three phase class IP55, ISO F, Class B. They
are accessible for maintenance by removing the panel inspected. The fans can be controlling with a
frequency converter for controlling the speed of rotation. The fan control process by default is set at a
fixed speed, but it can be configured with variable speed and controller by an external signal, or by a
pressure sensor.
