1 MAIN FEATURES
PERFORMANCE AND COMPACTNESS IN RECESSED CEILING INSTALLATIONS
The ducted units DUCTIMAX was designed for conditioning en-
vironments where it is required the installation of units in medi-
um head performance and reduced overall dimensions.
The range covers an air flow rate from 300 to 1200 m³/h distrib-
uted over 12 models. The heat exchanger allows the use of DUC-
TIMAX in the most different conditions.
The bearing structure in fact accommodates a heat exchanger
of 3 or 4 rows to which it is possible to combine an additional
heat exchanger of 1 or 2 raws for exceptional performance even
at low temperature differentials.
Heat exchanger can be optimized for centralized applications
such as district cooling. DUCTIMAX was designed to ceiling hori-
zontal installation.
The main condensate drip tray is situated inside the structure of
the unit and is at a positive pressure relative to the drain outlet
to facilitate condensate drainage.
A wide range of wall-mounted controllers is available, including
controllers of an electromechanical type and microprocessor
controllers with display.
The use of MYCOMFORT BASE, MYCOMFORT MEDIUM AND MY-
COMFORT LARGE or EVO allows connectivity of DUCTIMAX to
GARDA. Electric heating elements complete with safety devices
are available to integrate the hydronic operation.
The action of the G3 air filter can be combined with an air ioni-
sation system.
2 MAIN COMPONENTS
STRUCTURE
Realized in galvanized steel sheet, thermally and acoustically
insulated by self-extinguishing panels class 1.
Height reduced to facilitate installation in a horizontal position,
in false ceilings.
The bearing structure contains the tank for collecting and dis-
charging condensate.
ELECTRIC MOTOR
Single-phase asynchronous multi-speed electric motor with permanently connected capacitor and thermal protector, mounted on
vibration-damping supports.
AIR FILTER
Washable air filter, made of acrylic fibre, filtration class G2 or G3, applied on the air intake; may be pulled out from below.
AIR INTAKE
Air intake from the front or bottom of the unit, according to system requirements. See figure 15.2 p. 48 and 15.3 p. 48.
HEAT EXCHANGER
High efficiency 3 or 4 rows heat exchanger made of copper
tube and alluminium fins secured to the tubes by mechanical
expansion.
It is fitted with brass manifold and an air valve.The heat
exchanger, usually with left hand water connections can be
turned by 180°.
Available on request high efficiency heat exchanger optimized
for district cooling application.
FANS
Double suction centrifugal fans made with ABS or aluminium, with statically and dynamically balanced forward-curving blades,
directly coupled to the electric motor.
