The Galletti UTN 19A ducted fan coil, reference UT19A0L00000N0A, is a high-performance ductable hydronic terminal unit for 2-pipe installations. It features a 4-row coil, double-inlet centrifugal fans and a 3-speed electric motor, delivering up to 1,577 m³/h of airflow and a useful static pressure of up to 62 Pa.
Its high installation flexibility allows it to be installed in both horizontal and vertical positions, making it easy to integrate into suspended ceilings, technical spaces and duct networks. The specific UT19A0L00000N0A configuration has hydraulic connections on the left and is supplied without additional coil, valve, control panel, probes or filter, allowing the unit to be completed with the accessories best suited to each project.
The UTN 19A is designed for hydronic installations in which chilled or hot water from the generator circulates through a single main coil.
In a 2-pipe installation, the same hydraulic circuit is used alternately for cooling or heating depending on the season and the supply water temperature.
When properly sized, it can be integrated with systems such as:
Within Galletti’s nomenclature, the letter A identifies the high-performance ductable version.
In the UTN 19A, the main coil uses 4 rows of heat exchange, with copper tubes and aluminum fins fixed by mechanical expansion to achieve a large heat transfer surface.
The configuration code includes a type 0 motor, which Galletti identifies as a 3-speed electric motor.
The motor is mounted on anti-vibration supports, features a permanent capacitor and winding thermal protection, and is directly coupled to the centrifugal fan assembly.
The different speeds make it possible to adjust airflow, heating/cooling output, available pressure and acoustic emissions simultaneously to the needs of the installation.
The current official technical data sheet lists the following nominal airflow rates for the Galletti UTN 19A:
This range makes it possible to adapt operation to duct pressure losses and the air volume required in the conditioned space.
Available pressure also varies according to the selected speed:
These values should be used to properly size the duct network, taking into account pressure losses generated by ducts, elbows, transitions, filters, grilles and diffusers.
Galletti currently publishes the UTN 19A cooling performance with water at 7/12 °C and inlet air at 27 °C dry bulb and 19 °C wet bulb, in accordance with EN 1397:2021.
The published sensible cooling capacity is:
Actual performance will depend on inlet and outlet water temperatures, air conditions, hydraulic flow rate and selected speed.
For heating, the current official data is determined with water at 45/40 °C and inlet air at 20 °C.
These low water temperature test conditions are especially relevant for modern hydronic installations powered by a heat pump.
Under nominal cooling conditions, Galletti specifies:
The corresponding pressure drops in the main coil are:
With water at 45/40 °C, the official table indicates:
The corresponding hydraulic pressure drops are:
The UTN 19A uses 3/4" hydraulic connections on the main coil.
Reference UT19A0L00000N0A specifically includes the main coil connections on the left side, according to Galletti’s official configurator.
The range’s coil allows different layouts depending on the requested configuration, so the orientation corresponding to the specific commercial reference must be respected.
The reference does not include a second heat exchange coil, confirming its configuration for a 2-pipe system.
In 4-pipe installations, Galletti uses an additional independent coil to provide chilled and hot water circuits simultaneously, a configuration that does not apply to this reference.
The UT19A0L00000N0A coding indicates that the control valve is not included in the base supply.
Galletti offers 2-way and 3-way valves as accessories, as well as independent pressure valves with different actuator types.
The valve should not be considered included unless expressly added to the order.
The configuration is also supplied without a control panel from the factory.
The UTN range supports different optional control solutions, including:
This makes it possible to select the control system according to the hydraulic design and the project’s automation system.
The reference code also specifies that no additional probes are included.
Galletti optionally offers probes for:
The letter N in the configurator identifies this version as without filter.
When the project requires filtration, Galletti offers optional modules:
The filtration module must be selected as an accessory and sized taking into account its pressure drop.
The UTN uses double-inlet centrifugal fans designed to reduce acoustic emissions.
The fans are statically and dynamically balanced to limit vibrations and stresses transmitted to the motor shaft.
Electrical input power varies according to speed:
The nominal power supply is 230 V single-phase at 50 Hz.
The certified total sound power for the UTN 19A is:
The sound power radiated plus intake is 59 / 65 / 69 dB(A), while the sound power associated with discharge is 57 / 63 / 68 dB(A).
The perceived sound level in the room will also depend on the duct design, suspended ceiling, insulation, grilles and construction characteristics of the installation.
One of the main advantages of the UTN range is the possibility of horizontal or vertical installation.
Galletti incorporates a condensate collection system prepared for both orientations, making it easier to integrate the fan coil in suspended ceilings as well as vertical technical solutions.
The intake position can be changed during installation, increasing flexibility when connecting the air return to the configuration available on site.
This feature makes it easier to adapt to existing ducts or installations where technical space imposes specific limitations.
The casing includes a pre-punched circular Ø100 mm opening for outdoor air supply.
This makes it easier to connect a fresh air intake when the overall ventilation and air conditioning system design requires it.
The range can be connected using accessories to:
Galletti offers connection panels, plenums, fittings and other accessories to adapt the fan coil to different air distribution systems.
The load-bearing structure is made of galvanized steel sheet and features internal closed-cell insulation with thermoacoustic properties.
The insulation helps reduce sound transmission and limit condensation on the external surfaces of the unit.
The main heat exchanger is made of copper tubes and aluminum fins fixed by expansion.
The 4-row configuration of the 19A model provides a large exchange surface for operation in both cooling and water heating.
The official dimensional drawing groups models 16D, 16A and 19A within the same casing.
Dimensions A, B, C and D correspond to specific dimensions in the technical drawing and should be used together with the Galletti plan to define fixings, ducts and service clearances.
Galletti offers numerous accessories to adapt the fan coil to each project:
These items are optional and should not be considered included in reference UT19A0L00000N0A unless expressly stated in the order.
The Galletti UTN 19A UT19A0L00000N0A combines a 4-row coil with up to 1,577 m³/h airflow and 62 Pa available pressure, offering a ductable solution for 2-pipe hydronic installations.
Its horizontal or vertical installation capability, left-side connections, outdoor air preparation and wide range of accessories make it suitable for residential and commercial projects with different distribution and control requirements.
The configuration is supplied without valve, control, probes or filter, allowing the professional to select these elements independently according to the characteristics of the hydraulic and control system.
