Nominal sizes
Ceiling swirl diffusers in air conditioning systems create a swirl to supply air to rooms. The resulting airflow induces high levels of room air, thereby rapidly reducing the airflow velocity and the temperature difference between supply air and room air. Ceiling swirl diffusers allow for large volume flow rates. The result is a mixed flow ventilation in comfort zones, with good overall room ventilation, creating only very little turbulence in the occupied zone. TROX INVISIBLE DIFFUSERS (TID) feature invisible or inconspicuous installation methods. The swirl unit required for the swirling air discharge is not visible from the room. The special shape of the discharge nozzle allows the swirl effect to be used even behind perforated standard metal ceiling tiles or factory-made perforated plate diffuser faces. Type TID ceiling swirl diffusers have fixed air control blades. Air discharge is horizontal, with an omni-directional flow. The supply air to room air temperature difference may range from –12 to +10 K. A damper blade in the plenum box simplifies volume flow rate balancing for commissioning. To give rooms a uniform aesthetic, Type TID diffusers may also be used for extract air.

The quick sizing table gives a good overview of the possible volume flow rates and the corresponding sound power levels and differential pressure levels for the combinations with the different perforated plate diffuser faces. The minimum volume flow rates apply to a supply air to room air temperature difference of –6 K. The maximum volume flow rates apply to a sound power level of approx. 50 dB (A) with damper blade position 0°. Exact values for all parameters can be determined with our Easy Product Finder design programme. The quick sizing tables for various sample perforations are listed below:

Specification text
Ceiling swirl diffusers for invisible or inconspicuous installation behind standard metal ceiling tiles or factory-made perforated plate diffuser faces. The ceiling swirl diffuser is suitable for comfort and industrial zones and is installed as a supply or extract air diffuser in the suspended ceiling. The swirling element with fixed air control blades enable a horizontal swirling supply air discharge creating high induction levels so that the airflow velocities and temperature differences are quickly reduced. The special shape of the discharge nozzle allows the ceiling swirl diffuser to be used behind perforated standard metal ceiling tiles, which must not be thicker than 1.0 mm, and should ideally be preferably less than or equal to 0.7 mm thick, without any visual interruptions in the ceiling appearance. The ceiling swirl diffuser can be combined with all types of ceilings using a factory-made perforated plate diffuser face. The ready-to-install functional unit, consisting of a specially shaped discharge nozzle, swirling element with fixed blades and spigot, is always coated in black and can be connected directly to the on-site air duct system or combined with a Type AK-Uni plenum box. In the case of a vertical connection, suspension lugs are provided for on-site fixing to the spigot. The plenum box has drilled holes for on-site fixing. All spigots are suitable for ducts according to EN 1506 or EN 13180. The sound power level of the air-regenerated noise is measured according to EN ISO 5135.
