THE MAXIMUM EXPRESSION OF TECHNOLOGY AT THE SERVICE OF THE
HOTEL INDUSTRY
GALLETTI’s extensive experience in the manufacture of fan coil units and
development of refined control logics was combined with the know-how of
EBM-PAPST in the construction of fan drive assemblies in order to create
ESTRO GT.
The ESTRO GT design was developed specifically for the hotel industry,
where fan coil units represent the most convenient solution for air
conditioning rooms given that they are efficient, reliable, quiet and simple
to maintain.
With ESTRO GT it’s almost like adding another star!
ESTRO GT uses fan drive assemblies with GreenTech technology, which
means BLDC motors directly integrated with the fan assembly and inverter
and 70% reductions in electricity consumption compared to traditional AC
motors. The low electricity consumption is the ideal solution for installations
in hotels, where the fan coil unit is running 80% of the time on average.
The extremely low noise levels and the possibility of continuous modulation
of the fan speed fully satisfy guests’ needs in terms of flexibility of use
and quiet operation. ESTRO GT fan coil units use MYCOMFORT LARGE and
EVO microprocessor control panels, which, thanks to the analogue outputs
and refined adjustment logics, perfectly control the operation of the BLDC
motors and modulating valves.
A wide range of accessories completes the offerings for recessed ceiling
installation.

1.2 MAIN COMPONENTS
Cabinet
Composed of a painted steel sheet panel, side panels, air outlet grille
(swinging by 180°) and back suction grille built from ABS.
Structure
Built from galvanised steel sheet of extra thickness, heat and sound insu-
lated by means of Class 1 self-extinguishing panels. FU - FC - FF versions
are suitable for either vertical or horizontal installation thanks to the dual
condensate collection and drainage system.
Heat exchanger
High efficiency heat exchanger made with copper piping and aluminium
fins, provided with brass manifolds and vent valve. The water connections
are reversible at the time of installation. On request it is possible to mount
an additional heat exchanger for 4-pipe systems.
Air filter
Honey-comb polypropylene washable air filter, easily removable for main-
tenance operations. On FU version the air filters are fitted onto the air inlet
grille.
Electric fan with GreenTech BLDC motor
ESTRO GT uses the exclusive GreenTech technology of EBM-PAPST.
Permanent magnet BLDC motor with inverter integrated in the fan assembly,
protection rating IP44, insulation class F and ball bearings. Polypropylene
PP) volute. Centrifugal fan with forward-curving blades made of glassfilled
polyamide PA 6. Conformity with 2017 ERP Directive.
Backed by thirty years of experience in the manufacture of fan coil units
Galletti introduces the new ESTRO BLDC line.
Galletti fan coils can be equipped with a permanent magnet (brushless)
electric motor, controlled by an inverter, which enables continuous adjustment
in the number of fan revolutions.
The great advantage of brushless motors is the significant reduction in
power consumption, which in instant operations reaches up to a 1/3of that
of conventional motors and at around 50% in integrated operations, with the
corresponding reduction in CO2emissions!
The DC Inverter technology allows to continuously adjust the air flow to the
actual needs of the environment by considerably reducing the fluctuations in
room temperature that are typical of step-by-step adjustments.
1.3 BLDC TECHNOLOGY
The direct consequence is also the reduction in the noise emission of the fan
coil, which is now proportional to the demands of the environment.

THE CONTROL
The operation of the unit with brushless motor is managed by the
MYCOMFORT LARGE control panel, using an analogue output (0-10V) which
is connected to the inverter.
The Galletti brushless fan coil thus represent the state of
the art due to the possibility of regulating the operation,
depending on the temperature of the air, its relative
humidity, the temperature of the water and based on the
programmable time slots.
By means of the digital outputs it is possible to switch on
and off external units or devices such as chiller, boiler,
pumps, water circulation pumps, etc.
Another analog output makes it possible to control the
modulating valves.
