Thermo-ventilation air unit UTO-UTV - Residential terminal air unit with Brushless EC motor
EMMETI proposes a new line of thermal ventilating units with
BRUSHLESS-DC technology for ceiling-installation “UTO” or built-into
walls “UTV” for the cooling and heating of residential or commercial
environments (offices, shops, hotels) and they have been designed to
meet the growing needs of environmental comfort, energy saving and use
with hot or cold water produced by a heat pump.
The air is distributed within the rooms thanks to a ducting that is
simple to install and easy to place on the ceiling.
Thanks to the presence of Brushless motors, the units are also
• Continuous variation (from 0-100%) of the air flow and consequent
modulation of the heat capacity in function of the real needs of
• Maximum silence of operation (the unit finds operating balance at a
lower number of revolutions and therefore produces less noise.
• Saving on electrical energy consumption due to the greater efficiency
and longer motor life compared to traditional AC motors.
• Supporting structure in galvanised steel of considerable thickness
with holes (slots) for the fixing of the structure directly to the
wall/ceiling + internal thermal acoustic insulation
• Condensation collection basin equipped with drain and thermal
insulation (class M1).
For the vertical version only: Condensation Drain Funnel with 20 mm
connector, in plastic (as standard on the same side as the hydraulic
connections) that ends on the outside of the shoulder of the unit, for
an easy and quick connection to the condensation evacuation pipe.
• High efficiency thermal exchange battery made of copper pipe and
aluminium fins locked by means of mechanical expansion.
Battery connections equipped with an anti-torsion system, manual air
release valve, and manual water evacuation valve.
Standard connections on the left: Battery tested to 30 Bar pressure,
suitable for operating with water up to a maximum pressure of 15 Bar.
• Ventilation unit comprises 1 or 2 double intake centrifugal fans with
the Latest Generation Plastic Impellors (forward curving blades)
directly coupled to the electric motor.
Mounted on elastic supports with dampers.
Fan statically and dynamically balanced. Fans of large diameter (= high
air flow and high static pressure) with low number of revolutions (= low noise).
Latest generation Brushless EC Motor, permanent magnet, without brushes,
continuous current, equipped with control electronics (Inverter).
IP 40, Class B, electric cables protected with double insulation.
Constructed according to international standards, 230Vac-1Ph-50/60Hz.
Continuously adjustable number of revolutions 0-100% (and therefore of
the air-flow rate and consequently of the potential cooling/heating)
through 0…10Vdc. modulating control signal.
Inverter with Dip-switch to set different types of motor control
software (following software available: “Constant speed”; “Constant
torque”; “Constant tension”) + Dip-switch to redistribute the operating
range on a new more limited range (from 0…10Vdc up to 0….6,5Vdc).
Ventilation unit is easy to remove (fixed with only 4 screws).
• The standard unit is delivered equipped with the terminal plate
already mounted on the unit (as standard on the side opposite the
