The MCmultizone adiabatic humidification system is ideal for the humidification
of medium/large industrial environments and large volumes of air, in the duct
and for air handling units.
The system uses compressed air to atomise the water into very fine droplets
that evaporate spontaneously in the air, humidifying and cooling it. In fact,
evaporation occurs by “absorbing” sensible heat from the air that,
as a consequence, is cooled.
The system features the following main parts•
• control cabinet, fitted with the electronic controller;
• special atomising nozzles. The nozzles can be installed in the AHU/duct
or directly in the room being humidified/cooled;
• manifolds for installation in the duct;
• UV steriliser lamp and protective filters.
Control cabinet
This contains the electronic controller that manages the supply of water and
compressed air to the nozzles. The water is atomised based on an external control
signal or, in the case of independent control, so as to maintain the humidity/temperature
set point.
This also manages all the automatic cycles, such as cleaning the nozzles and
washing.
The system has the ability to control the humidity independently in multiple
zones (rooms, AHUs, cold rooms) using a master-slave layout. The layout has
one MASTER and multiple SLAVES, up to 5, connected in a pLAN (3 wires, digital
communication). The Master is fitted with a display for accessing the readings,
viewing the status and messages on the master and the slaves. The slaves have
their own internal control and can be set to continue operating even if the
connection to the master is interrupted.
The Master-Slave configuration can be used as follows:
• high capacity applications: applications in rooms or ducts where
more than 230 kg/h of humidification is required, and thus more than one MC
cabinet. The control signals (probes, external signals, limit probe) are connected
to the MASTER only. The master and the slaves generate a humidification/cooling
capacity that is proportional to demand and their capacity. In this way, a system
can be developed with a capacity up to 1380 kg/h;
• MULTIZONE applications: applications in multiple zones, rooms
or ducts, each with its own humidity/temperature set point. Note that, in the
case of installations in large spaces, these can be divided into zones, each
with their own humidity/temperature probe, using the multizone Master-Slave
system described here. Each cabinet, master and slave, receives the signals
(probes or external signals) from the corresponding zone, and generates the
capacity required to reach its own set point.
All the parameters, the status and messages of all the cabinets can be viewed
and edited from the user interface on the MASTER.
