1. INTRODUCTION AND ASSEMBLY
1.1 MCmultizone atomising humidifi er
Humidifi cation system designed for medium/large installations, where are
a large humidifi cation capacity is required with low energy consumption
(high water fl ow without excessive energy costs).
Water and air, suitably regulated in terms of fl ow-rate and pressure, are
delivered to the atomising nozzles in two separate lines. Due to the
special shape of the nozzles, the jet of water is nebulised into a mist of
very fi ne droplets (5 to 8 microns).
The atomised water can then easily change state and vaporise. The
energy required for this transformation is supplied by the ambient air.
For each litre/hour of water that vaporises, in fact, the environment
gives up around 590 kcal (149 SkJ) of energy. Consequently, there is a
decrease in temperature in the environment being humidifi ed, and this
process may be useful in many applications (adiabatic cooling). A timed
automatic system ensures the atomising nozzles are cleaned periodically,
preventing debris or scale from causing malfunctions.
Each atomising head is fi tted with a small piston for cleaning any deposits,
whenever the control cabinet stops operating. The system guarantees
optimal atomisation at all times and prevents dripping when the
installation is off . The electronic controller ensures the ambient humidity
is kept at the required value, showing the relative humidity read in the
room on the display.
The MCmultizone system is essentially made up of: control cabinet and
compressed air-water supply, atomising nozzles, nozzle assembly kit.
1.2 Models
The MCmultizone humidifi ers are available by:
•
size: with maximum fl ow-rate of 60 l/h (MC060*), or 230 l/h (MC
models230*);
•
type of capacity modulation: ON/OFF (MC models***C*), or
proportional (MC models***H*);
•
power supply: single-phase 230 Vac 50 Hz (MC models****D*), or 110
Vac 60 Hz (MC models****1*);
•
version: Master (MC models*****M*), or Slave (MC models*****S*);
•
type of water used: mains, drinking (MC models*********0), or
demineralised/aggressive (MC models*********1).
Models recommended for specifi c applications:
•
for duct applications (or air handling units), proportional units with
high humidity limit probe are recommended.
•
for applications directly in the room, both ON/OFF and proportional
control units are recommended
