AIRFLOW MEASUREMENT
This technology measures total pressure and air volume allowing easy commissioning, the limiting of maximum diffuser volumes to meet a building’s design, integration with the building BMS, calculation of HVAC energy consumption per zone and aids troubleshooting of problem zones that are out of temperature control.
TIGHT SEALING GASKET
A standard diffuser is not designed to seal completely when fully closed and can waste energy when this is required. A standard diffuser without a tight sealing gasket will supply between 30 and 13% volume flow at 0% control disc position (leakage depends on the diffuser neck size).
