DF units are designed for efficient room heating and cooling where high capacity, ultra-quiet operation, and maximum energy efficiency are required. Thanks to their high heating and cooling capacity, these units can be used as the main heating and cooling devices even in buildings with low energy efficiency.
Their compact design, with a height starting from 238 mm, allows the fan coil units to be installed in low ceiling spaces, making them particularly suitable for renovated buildings, hotels, or offices with limited installation height. The very low noise level ensures comfortable operation in spaces with strict acoustic requirements, such as residential areas, hotel rooms, offices, or conference halls.
The units are available in 2-pipe or 4-pipe connection configurations. 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 capacity. Models with AC or DC fans are available, enabling an optimal balance 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 pans with an anti-corrosion coating allow the units to operate reliably below the dew point, making the fan coils suitable for continuous cooling mode.
Copper-aluminium heat exchangers with a hydrophobic coating improve condensate removal, increase heat exchange efficiency, and reduce dirt accumulation, thereby contributing to lower energy consumption and easier maintenance. All models are equipped with washable nylon air filters that are easy to remove and clean.
The fan coil units operate efficiently with low-temperature heat sources such as heat pumps or condensing boilers. Their low thermal inertia allows heat or cooling to be delivered only according to actual demand, significantly reducing energy consumption and preventing rooms from overheating or overcooling.
