1 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

(Φ100 mm);

> wide range of accessories for effectively.

2 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/m3.

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.
