TTC - Active Ceiling Supply Air Diffuser


+ DOCUMENTATION + CASE


Efficient Ventilation with Minimal Energy Use through Demand Control

Good ventilation with minimal energy consumption through demand control.
The active supply air diffuser, TTC, enables a good indoor climate with low installation costs and very low operating costs. Reference installations have shown savings of 50% in fan power, 95% in air heating (preheating of air), and 10% in radiator heating compared to similar solutions using CAV. But the product isn't just energy-efficient; evaluations have shown that TTC is approximately 30% cheaper than similar functionality achieved with CAV, chilled beams, and standard lighting control. With optimization features for the entire system—operating hours, pressure, supply air temperature, economy mode, and fixture lifespan, among others—the building's energy costs can be significantly reduced. TTC replaces our previous active ceiling supply air diffuser, TTD.

Principle

How is this possible? The principle behind TTC is to vary the height of the slots based on demand, thereby maintaining the discharge velocity at different flow rates, allowing cold air to be used to cool the room. For most of the year, the air does not need preheating; heat exchange is sufficient. Combined with demand control using presence and temperature sensors, energy use can be drastically reduced.

Built-in Sensors - Lower Installation Costs and Greater Flexibility

TTC includes all necessary sensors and the controller built into the diffuser, providing optimal room control tailored to actual needs. The diffuser comes standard with the following sensors:

  • temperature sensor
  • presence sensor
  • duct temperature sensor
  • duct pressure sensor
  • pressure sensor for airflow calculation

Quiet and Draft-Free

With patented technology, TTC achieves unique sound performance: 27 dB(A) at 100 Pa and 50 l/s. This allows the existing duct system to be extensively used in renovation projects.

Operational Reliability and Accessibility

TTC is equipped with technical solutions and components that make the diffuser very reliable in operation. The current airflow and room temperature, along with other values and settings, can be easily accessed either via a handheld device at the individual diffuser or through a central user interface via network communication.
