aDCV – adaptive, demand-controlled ventilation

Thanks to the patented adaptive pressure control, up to 43% savings on energy costs can be achieved – compared to a system with constant pressure control (VAV), and up to 19% compared to a demand-controlled system with constant pressure control (DCV).

The patented adaptive pressure control provides the possibility to optimize operation with constant pressure regulation of ventilation systems with variable airflows.

More benefits of patented adaptive pressure control

Use aDCV and achieve energy savings with lower pressure drop and lower noise level

With constant pressure regulation (VAV), a constant pressure is provided through the ventilation system at all air volumes (Fig.: 1 – blue line). 

With variable volume flow systems (VAV) - e.g. zone control via CO₂ or humidity, however, the ventilation system requires less pressure loss in the system at a lower air volume (Fig.:1 – red line) - and this is precisely possible with aDCV.

SFP value

aDCV – the patented adaptive pressure control reduces the pressure of the ventilation system when the airflow decreases and only provides the necessary pressure.
