Greenheck recently expanded its Air Measuring Damper (AMD) line with the addition of the AMD-TD series of thermal-dispersion-based airflow-measuring dampers.
The AMD-TD series combines the functionality of a highly accurate thermal-dispersion airflow station and a low-leakage control damper to control airflow volumes to a target set point. Featuring Vari-Green airflow-measurement probes and transmitters, AMD-TD series dampers accurately measure airflow down to 100 fpm. An optional factory-supplied controller makes the AMD-TD series a turnkey solution for the measurement and control of airflow. Factory-supplied controllers are available with analog or BACnet MS/TP operation.
Four models are available: AMD-23-TD with 3V style blades, AMD-33-TD with fabricated airfoil blades, AMD-42-TD with extruded aluminum blades, and AMD-42V-TD with vertically oriented extruded aluminum blades.
