Description

Ceiling swirl diffusers in air conditioning systems create a vortex supply of air for good mixing with the room air. The air flow obtained at the outlet of the diffuser allows one to achieve high ejection values, thereby quickly reducing the flow rate and leveling out the temperature difference between the supply air and the air in the room. Ceiling swirl diffusers are used for high air flows. As a result, there is a mixing of air flows in comfort zones, with a good distribution of air jets throughout the room and a small turbulent vortex in the area where people are present.

Ceiling swirl diffusers of the TDF series have fixed guide vanes. Air supply is carried out in a horizontal direction in a fan-shaped manner. The temperature difference between the supply air and the room can range from –12 to +10 K.

Flap blade (optional) to balance air flow simplifies operation. The metering point and damper blade with flexible rod (optional) allow you to adjust the air flow when the front panel is installed.

To create an attractive, holistic room design, TDF series diffusers can also be used for exhaust ventilation.
