Functional description

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.

Design ceiling swirl diffusers are characterised by a diffuser face plate with a particular pattern. The swirl unit required for the swirling air discharge is situated inside the plenum box and hence not visible from the room.

Type XARTO ceiling swirl diffusers have fixed blades. Air discharge is horizontal omni directional. The supply air to room air temperature difference may range from –12 to +10 K.

A damper blade simplifies volume flow rate balancing for commissioning.

To give rooms an aesthetic, uniform look, Type XARTO diffusers may also be used for extract air.

Quick sizing tables provide a good overview of the volume flow rates and corresponding sound power levels and differential pressures.

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.

Type XARTO swirl diffusers meet the most demanding requirements of technical function, comfort, and design.

Diffuser faces come in classic, modern and flamboyant styles and can be creatively integrated with all types of ceilings. They form in fact an attractive design element for building owners and architects.

The combination of swirl unit, newly developed equalising element and innovative plenum box provides high volume flow rates, a low sound power level and low differential pressure.

The air control blades of the swirl unit have three-dimensionally profiled contours to create an efficient swirl. As a consequence, the air velocities and temperature differences in the occupied zone are very low, and the level of comfort is excellent.

A spigot with double lip seal provides a low-leakage connection of the plenum box to the ducting, and a damper blade for volume flow rate balancing simplifies commissioning.

  • Preferably for rooms with a clear height up to 4.0 m
  • Flush ceiling installation
  • Freely suspended installation only with an extended border (supply air variant)
  • Horizontal duct connection
  • If necessary, carry out volume flow rate balancing with the damper blade

Volume flow rate balancing

When several diffusers are connected to just one volume flow controller, it may be necessary to balance the volume flow rates.

  • The diffuser face can be removed to access the damper blade; the damper blade can then be set in 15° intervals between 0 and 90°
