Operating principle
Fig.1.
Halton Max Ultra Circular (MUC) has two ultrasound sensors for airflow measurement.
The damper can function either as a supply or an exhaust unit. It maintains the required airflow
through ultrasound measurement, regardless of variations in the room conditions or duct pressure.
The damper has an airflow controller, two ultrasound sensors for airflow measurement, and an
actuator for controlling the damper blade.
The airflow controller can be controlled via:
•
Modbus RTU,
•
the control panel,
•
an analogue signal.
All three control modes are synchronized between each other. The airflow measurement includes
temperature and duct type connection compensations, providing accurate and reliable airflow
measurements even at small safety distances.
Room conditions can be adjusted
•
manually from an end-user interface
