DF units are designed for efficient space heating and cooling where high output, extremely quiet operation, and maximum energy efficiency are required. Thanks to their high heating and cooling capacity, the units can be used as primary heating and cooling devices even in buildings with low energy efficiency.
The compact design, with a height starting from 238 mm, allows fan coil units to be installed in spaces with limited ceiling height, making them particularly suitable for renovation projects, hotels, and offices with restricted installation space. The extremely low noise level ensures comfortable operation in areas with strict acoustic requirements, such as residential spaces, hotel rooms, offices, and conference halls.
The units are available with 2- or 4-pipe connection options. The 4-pipe system provides maximum heating and cooling flexibility, allowing both modes to be controlled independently, while the 2-pipe system is focused on maximum instantaneous output. Models with AC or DC fans are available, enabling optimal balancing of energy consumption, noise level, and control accuracy.
The casings are made of corrosion-resistant galvanized steel, ensuring long-term reliability. Integrated one-piece, thermally insulated condensate drain trays with anti-corrosion coating allow the units to operate reliably below the dew point, making the fan coils suitable for continuous cooling operation.
Copper–aluminium heat exchangers with hydrophobic coating improve condensate drainage, increase heat exchange efficiency, and reduce dirt accumulation, contributing to lower energy consumption and easier maintenance. All models are equipped with washable nylon air filters, which can be easily removed and cleaned.
The fan coils operate efficiently with low-temperature heat sources, such as heat pumps or condensing boilers. Low thermal inertia allows heating or cooling to be supplied strictly according to actual demand, significantly reducing energy consumption and preventing space overheating or overcooling.
