The bottom of the cassette unit consists of a panel with a circular air discharge grille. With recirculation units, the air intake and discharge take place via the same grille panel. The air is drawn in through the perforated pattern in the middle of the panel. After the air has been heated or cooled, it is blown evenly into the room across 360° via the air discharge openings on the side of the grille. The circular air discharge pattern generates an optimal and even air distribution, which ensures optimal penetration and air circulation even at low air speeds.
Technology
Auto-Adjustable Ring The air discharge grille of units that can both heat and cool is fitted with a patented adjustable discharge ring. The unit adjusts the ring automatically and in doing so selects the air discharge angle that best fits the particular heating or cooling. Consequently, the downward penetration and distribution of the air are always guaranteed.
Fixed Setting Air Discharge Angle Units that either heat or cool only have a fixed setting for the discharge angle and do not have an adjustable ring.
