The MTC, like the MTN, is a self-regulating reactive ceiling air diffuser. This diffuser is designed for demand-controlled ventilation where the airflow from multiple diffusers is managed via a common damper on the supply air duct. 

• The MTC is suitable for variable airflow rates up to 115 l/s at 30 dB(A).
• Air is distributed along the ceiling, and at just 1.5 meters from the diffuser edge, the air temperature rises to 21ºC from 15ºC.
• The MTC uses the same type of diffuser box as the TTC ceiling diffuser, allowing it to be converted to an active diffuser if needed. 

The diffuser has a fixed bottom plate, making it externally similar to the active TTC air diffuser when there is no airflow.

Application Areas

The MTC is particularly well-suited for schools, shops, conference rooms, cafeterias, and other areas where demand-controlled ventilation is desired.

No Draft Even with Cold Air and Low Airflows

The MTC performs significantly better than a nozzle diffuser when airflow drops below 40% of the maximum. See the attached video clips for more details.
