Technical specifications

The range of UTN duct units has been designed to air condition rooms where the installation of duct units is required.

Thanks to the engineering solutions adopted, the UTN units offer high application flexibility:

Horizontal or vertical installation, thanks to the design of the water drip system.

May be connected to flexible circular ducts (Ø 200mm) or rectangular shaped ducts.

Air intake direction to be arranged during installation.

Bearing structure built from galvanised steel sheet, insulated with condensation proof, soundproof material, inspection panels, fresh air intake setting, quick fastening slots.

Double suction aluminium centrifugal fans, with inserted blades.

Three-speed electric motor.

High efficiency heat exchanger made with copper piping and aluminium fins.

Water drip tray and drain outlet, suitable for vertical or horizontal installation.

A broad range of accessories to meet every type of installation requirement.

Control panels and air filter available as accessory.

Main components

Structure

Made of galvanized sheet steel insulated with sound-deadening, heat-insulating, self-extinguishing closed-cell material to reduce noise emissions and prevent the formation of condensate on the outside surface.

Heat exchanger

It is composed of copper tubing and aluminium fins fixed by expansion. Water connections are reversible An additional exchanger is available for installing the unit in 4-pipe systems.

Fan

The aluminium fans are of the centrifugal type, with double suction and staggered blades to reduce noise emissions. They are statically and dynamically balanced to minimize the stresses transmitted to the motor shaft.

Filter module

The air filter, made of regenerable acrylic fibre, is available as an accessory in filtration classes G2 or G4.

Electric motor

Three-speed electrical motor, mounted on vibration damping couplings, directly connected to the fans, with permanently activated capacitor and winding thermal protection.

Condensate collection and drainage system

It consists of two insulated galvanized sheet steel trays designed for horizontal and vertical installation.
