Main Components - Galletti ART-U Serie Installations-, Bedienungs- Und Wartungsanleitung

MAIN COMPONENTS

Cabinet
The elegant front panel consists of two sheets of aluminium
with a polyethylene core and possibly a polyester-based surface
coating. It is a light but very resistant material, created for cov-
ering façades in the building sector. The side panels are made of
UV-stabilized ABS to maintain the colour over time.
The polyethylene core acts as a flexible filler and thermal in-
sulation while the aluminium provides structural strength and
aesthetics.
Conveyors
Made of high-density polystyrene. They are designed to opti-
mise the air flow inside the hydronic indoor unit allowing opti-
mal distribution of the air flow in the coil and low noise in every
operating mode.
Upper grille
Consisting of adjustable fins made of anodised aluminium, avail-
able in the version for on-board or wall-mounted control. The
ABS combs support the grilles and prevent them from being
bent, thus always guaranteeing the user's safety.
Wall-mounted control unit version has a continuous upper grille.
In the version for on-board control, the grill has two side doors
to allow access to the control.
Front grille
Stabilizes the operation of the tangential fan unit and is
equipped with a stainless steel filter.

ART-U
Electric motor
Permanent magnet BLDC motor with inverter integrated in
the ventilation unit. An IP44, protection rating is guaranteed;
therefore, dust inside is avoided and resistance to water spray
is guaranteed.
Heat exchangers
With high efficiency turbocoil-type heat exchanger, and made
with copper tubing and aluminium fins, it is equipped with brass
manifolds and a vent valve.
The hydrophilic treatment is applied to the fins as a standard
treatment, to increase their efficiency during cooling.
On standard version water connections are on the left. Water
connections on the right on request.
Air filter
Honey-comb polypropylene washable filter, easily removable
for maintenance operations.
Tangential fans
Tangential fan, statically and dynamically balanced to reduce its
noise during operation.
The ABS used for the blades guarantees, in comparison with
metal fans, a reduction in vibrations and an absence of bending
along the rotation axis.
The blades are alternated with intermediate reinforcement disks
in order to increase their sturdiness.
