Technical characteristics

DUCTIMAX i completes the range of ductable units using inverter controlled BLDC motors.

The distinctive aspects of the DUCTIMAX design are augmented by the benefits of brushless technology in terms of a reduction in power consumption and consequent reduction in CO2 emissions, an increase in operating flexibility as a result of modulating the air flow rate, and an increase in the temperature and humidity and acoustic comfort level. Further advantages are the installation flexibility and the reduction in the amount of time necessary for setting operation during the installation phase, due to the continuous modulation of the air flow rate.

The DUCTIMAX range is comprised of 12 models with air flow rates from 300 to 1200 m3/h and nominal cooling capacities of up to 8 kW.

Continuous modulation of the air flow and the use of high-efficiency heat exchangers enables operation also with small air – water temperature differences. The heat exchangers can also be optimized in their circuits for centralized applications, such as district cooling.

Operation is controlled by microprocessor-type wall-mounted control panels with displays, such as the MYCOMFORT LARGE and EVO models.


 

Main components

 Fans

Fans

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

 BLDC electric motor

BLDC electric motor

Permanent magnet motor The unit is equipped with an inverter board to control the motor, that makes it possible to precisely set the maximum rotation speed of the motor (control signal 0-10 V).

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. 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.

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.
