MEAN FEATURES
The new range of UTN high pressure fan coils units has been designed for
conditioning rooms that require the installation of ducted units.
Proposed in 12 models with air flows from 600 to 3000 m3/h, the UTN units
are characterized by a wide applicative flexibility thanks to the special
constructive solutions.
> possibility of installation both in horizontal and vertical position thanks
to the special conformation of the condensate discharge system;
> the air intake direction may be modified during installation;
> reduced height (280 mm up to model 16A);
> pre-shared element for the recycle of external air, standard on all models
(
Φ
100 mm);
> wide range of accessories for effectively.

VERSIONS AND COMPONENTS
Versions
UTN
air handling unit setup for 2-pipe systems
UTNDF
air handling unit setup for 4-pipe systems (2 heat
exchangers)
N.B. both version may be manufactured, on request, with pre-painted
panels.
Components
>
Load-bearing structure made of galvanized steel sheet of suitable
thickness, duly insulated with noise-proof/anticondensing material,
self-estinguishing in Class 1; the insulating material is characterized
by a thickness of 10 mm and a density of 90 Kg/m
3
.
The unit is completed by the following:
- inspections panels;
- setup for external air intake;
- fast-coupling slots.
>
Dual intake centrifugal fans made of alluminium, with statically and
dinamically balanced impellers, coupled directly to the electric
motor.
>
3 speed electric motor, equipped with permanently fit condenser and
thermal safety device, installed on vibrator damping supports.
>
Heat exchanger: high efficiency, made of copper tube and alluminium
fins secured to the tubes by mechanical expansion. It is fitted with
brass manifolds and air valves. The heat exchanger, normally
supplied with left hand attachments, may be turned by 180°.
>
System for collecting and discharging condensate setup either for
horizontal or vertical installation.
>
Terminal strip for fast - on electrical connections.
