Ceiling diffusers direct air from the air conditioning system into the room. 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 diffusers can be used for high air flow rates. 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 diffusers of the DLQL series are supplied with a special guide element that creates a horizontal air supply with high ejection levels. Horizontal supply of supply air from one to four directions. The temperature difference between the supply air and the room can range from –10 to +10 K.
To create an attractive, holistic room design, the DLQL series diffusers can also be used for exhaust ventilation.
