Energy Saving System
VAV SYSTEM : INTELLIGENT AIRFLOW, REDUCED CONSUMPTION
The VAV or Variable Air Volume system is an advanced airflow reducing strategy to limit the loads on HVAC systems. Unlike traditional auto bypass systems, the VAV system reduces the blower speed (and thus airflow) depending on the sash position. If the sash is fully open, VAV makes the exhaust run at maximum, when the sash is fully closed the exhaust is at minimum. The VAV is available for our Inventa range and offers you the following advantages.
