DF ducted fan coil units are designed for efficient room heating and cooling in residential, commercial and public buildings where high capacity, low noise operation and compact dimensions are required.
The low-height construction allows installation in suspended ceilings with limited installation space, making the units suitable for hotels, offices and renovation projects. Integrated condensate drain pans ensure reliable operation in cooling mode below the dew point.
The units are available in 2 and 4-pipe versions with AC or EC fan motors. Efficient operation with low-temperature systems, including heat pumps and condensing boilers, allows reduced energy consumption and precise room temperature control.
DF fan coils are equipped with corrosion-resistant galvanized steel casings, copper–aluminium heat exchangers and washable air filters for reliable long-term operation and simplified maintenance.
