Improved performance by subcooling circuit
The system performance is improved by enlarged heat transfer area of outdoor unit and subcooler heat exchanger.

Super high-stream fan
The outdoor units have been designed with a new super high-stream fan of Ø544 mm, reducing the sound level and in-
creasing its reliability, by the use of a three-blade design propeller.
This fan is much more aerodynamic than earlier models. It has a greater surface area in contact with the air and a better
turning angle, preventing turbulence and allowing the ventilator to be fitted lower.
Additionally, the rib structure synchronized with rotation flow from the fan reduces the air resistance at the air outlet grille.

Silent fan unit
Low noise due to the following aspects:
•
Combination of the three-blade and slim fan: The fan has been designed to have a lower body than traditional fans,
and achieves surprising results, with a noise reduction of up to 4dB (A).

DC fan motor: The smooth rotating fan motor with low vibration reduces the noise generation.
