Galletti fan coils

Galletti DUCTIMAX i fan coil units from Hevac

The new range of Galletti DUCTIMAX i fan coil units from Hevac comprises 12 models with air flow rates from 300 to 1200 m3/h and nominal cooling capacities of up to 8kW. Thanks to the use of inverter BLDC technology in the electric motors, the new units offer reduced power consumption; reduced CO2 emissions; increased operating flexibility; an increase in the temperature and humidity; and an improved acoustic comfort level.

Further advantages are

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 latter, coupled with the use of highefficiency heat exchangers, also enables operation with small air/ water temperature differences. The heat exchangers can also be optimised in their circuits for centralised applications, such as district cooling. Meanwhile, the action of the air filter (G2, G3 or G4) can be combined with an air ionisation system, available as an accessory.

Built from galvanised steel sheet, the units are heat and sound insulated by means of Class 1 self-extinguishing panels. Reduced height facilitates installation in a horizontal position in a false ceiling while 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 maintained at a positive pressure relative to the drain outlet to facilitate condensate drainage from the unit.

All DUCTIMAX i units are equipped with an inverter board to control the motor. This makes it possible to set the maximum rotation speed (control signal 0-10 V) precisely.

The double suction centrifugal fans are made with ABS or aluminium, with statically and dynamically balanced forwardcurving blades which are directly coupled to the electric motor.

The high-efficiency 3- and 4-row heat exchanger is made from copper piping and aluminium fins blocked to pipings by mechanical expansion, and 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 180º. High-efficiency heat exchangers optimised for district cooling applications are available on request.

Air filters are made of acrylic and come with filtration Class G2 applied on the air intake.
