Jet nozzles are the preferred solution wherever the supply air has to travel large distances from the point of discharge to the occupied zone. It is possible to adapt the discharge angle, and consequently the direction of the airflow, to heating or cooling mode. The supply air to room air temperature difference can be -12 - +20 K.


Cooling mode


Cooling mode is possible with a positive discharge angle of up to 30°. The supply air jet is directed towards the ceiling, but the higher density of cold air results in an increasing deflection of the air jet towards the floor as the distance from the jet nozzle increases. When the supply air jet reaches the occupied zone, both the supply air to room air temperature difference and the airflow velocity have been reduced to comfortable levels. This principle of operation allows for long throw distances.



Heating mode


Heating operation is possible with a negative discharge angle of -30° or less. The supply air jet is directed towards the occupied zone. Due to the lower density of warm air, the jet becomes buoyant. When the supply air jet reaches the occupied zone, both the supply air to room air temperature difference and the airflow velocity should ideally have been reduced.

The discharge angle can be changed manually or with a thermal or electric actuator.


A swirl unit and cap (optional) allow for reducing the throw distance to 65 % or 75 %.
