2.2 Air distribution with the Air-Injector
The patented air distributor – called the Air-Injector – is
the core element. The adjustable vanes are used to set
the air discharge angle. It depends on the air flow rate, the
mounting height and the temperature difference between
the supply air and room air. The air is therefore blown into
the room vertically downward, conically or horizontally. This
ensures that:
■ a large floor area is ventilated and heated by each

condens,
■ no draughts occur in the occupied area,
■ the temperature stratification in the room is reduced, thus
saving energy.
