VHD Pressure Dependant VAV Diffuser
The VHD is an active ceiling diffuser for supply air. The active diffuser shall be made of painted steel with a white (RAL 9003) standard colour. Air shall be introduced into the space through the side slots and perforated front panel, ensuring a high mixing rate.
The diffuser shall be connected to a balancing plenum designed for the active diffuser installation and equipped with a measurement and adjustment module.
In the demand-based ventilation (DBV) and variable air volume (VAV) systems, room conditions can be guaranteed to be without a risk of draughts, at both the maximum and minimum airflow rate.
