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.

 
ASHRAE compliance at lower rates – 80FPM
Reduced HVAC procurement costs
Reduced energy bills
Compliance with our other energy saving strategies to give you even more savings
