Duct unit DUCTIMAX i Medium available head duct units with BLDC motor Modulation and efficiency in a recess ceiling-mounted unit The range is completed by DUCTIMAXi, which uses inverter BLDC technology in the electric motors. To the features of DUCTIMAX it adds the benefits of brushless technology, including a reduction in electricity consumption and consequent reduction in CO2 emissions, increase in operating flexibility thanks to the modulation of air flow and increase in the level of comfort in terms of temperature, humidity and noise levels. The range is made up of 12 models with air flows from 300 to 1200 m3/h. Continuous modulation of the air flow and the use of highefficiency heat exchangers enables operation also with small air – water temperature differences. The heat exchangers can also be optimized in the circuit for centralized applications such as district cooling. Operation is controlled from wall-mounted microprocessor control panels with display, such as the MYCOMFORT LARGE and EVO models which also enable DUCTIMAXi to be connected to ERGO. The action of the G3 air filter can be combined with an air ionisation system, available as an accessory. ERGO Supervision PLUS Permanent magnet BLDC motor Low electricity consumption Easy setup of ventilation section Heat exchanger up to 4 rows Compact dimensions Reversible water connections Can be integrated into the ERGO Incorporable ioniser Vast range of available accessories Unit for 2-pipe systems Unit for 4-pipe systems equipped with an additional 1-row exchanger for the hot water circuit Unit for 4-pipe systems equipped with an additional 2-row exchanger for the hot water circuit Besides assuring a big advantage in terms of energy efficiency, the inverter-controlled BLDC motor enables flexibility of installation and reduces the time needed to set up the ventilation section, thanks to the continuous modulation of air flow.

main components 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. Fans Double suction centrifugal fans made with ABS or aluminium, with statically and dynamically balanced forward-curving blades, directly...
