Technical characteristics

DUCTIMAX represents Galletti’s answer to the need for compactness and efficiency in ducted installations. The range of DUCTIMAX ductable units was designed for ceiling recessed installation; it is comprised of 12 models with air flow rates from 300 to 1200 m3/h and nominal cooling capacities of up to 8 kW.

A finned block heat exchanger with 3 or 4 rows allows DUCTIMAX to be used in a wide variety of operating conditions. It is possible to add another exchanger with 1 or 2 rows for exceptional performance even with low air/water temperature differentials. The heat exchanger can be optimized for centralized applications, such as district cooling, that are characterized by high thermal gradients.

The use of multi-speed motors (up to 7 speeds) allows proper sizing of the machine by correctly balancing performance and noise levels. The main condensate drip tray is situated inside the structure of the unit and is at a positive pressure relative to the drain outlet to facilitate condensate drainage.

The washable air filter is made with acrylic fibre and has a filter class of G2, G3, or G4. The structure makes it possible to combine a wide range of accessories on the air intake and outlet sides so as to obtain the optimal configuration of the unit.

A wide range of wall-mounted controllers is available, including controllers of an electromechanical type and microprocessor controllers with display. 

Main components

Heat exchanger

High efficiency 3 and 4 rows heat exchanger made with copper piping and aluminium fins blocked to pipings by mechanical expansion, provided with brass manifolds and air vent valve.The heat exchanger usually comes with water connections mounted on the left, but it can be turned by 180°. High-efficiency heat exchangers optimized for district cooling applications are available on request.

Air filter

Washable air filter, made of acrylic fibre, filtration class G2 or G3, applied on the air intake; may be pulled out from below.

Electric motor

Single-phase asynchronous multi- speed electric motor with permanently connected capacitor and thermal protector, mounted on vibration-damping supports.

Structure

Built from galvanised steel sheet, heat and sound insulated by means of Class 1 self-extinguishing panels. Reduced height to facilitate installation in a horizontal position in a false ceiling. The structure incorporates a drip tray and condensate drain outlet.

Fans

Double suction centrifugal fans made with ABS or aluminium, with statically and dynamically balanced forward-curving blades, directly coupled to the electric motor.
