TROX displacement diffusers type QSH · ISH are suitable for heating and cooling mode. The discharge direction is adapted to the operational situation by means of an integrated adjusting mechanism.

The diffusers can be operated by hand (chain pull) or by means of different variants of electric actuators. Automatic adjustment (without auxiliary energy) is also possible.

In the case type ISH, the cold air is discharged horizontally at high momentum. These displacement diffusers are ideal when varying supply air temperature differentials in the range from -8 K to +12 K apply, at installation heights of 3.5 to 10 m.
