Perfect for demand-based ventilation
Quick to install due to the individually pre-calibrated airflow values. This airflow damper is maintenance free because the dust doesn´t affect the measurement sensors.
Halton Max Ultra Circular has wide measurement range.
- Variable (VAV) and constant (CAV) airflow control applications
- Supply and exhaust installations
- Enables flexibility in terms of space layout design
- Available also for Halton Workplace applications
Overview
Circular airflow management damper using the ultrasound technique for airflow measurement.
Application areas
- Variable (VAV) and constant (CAV) airflow control applications
- Supply and exhaust installations
- Available also for Halton Workplace applications
Key features
- Insensitive to dust collection
- Enables flexibility in terms of space layout
- Individually calibrated for higher accuracies
- Low pressure loss for reducing the noise level
- Can be connected to Buildings Management System (BMS)
The airflow controller can receive the airflow control signal via
- Modbus RTU network variable,
- the control panel input,
- an analogue standard signal.
All three control modes are synchronized between each other. The airflow measurement includes temperature and duct type compensations, providing accurate and reliable airflow measurements even at short distances from airflow disturbances in the ductwork.
Operating principle
Fig.1. Halton Max Ultra Circular 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 airflow and pressure variations in the ductwork.
The damper has an airflow controller, two ultrasound sensors for airflow measurement, airflow temperature sensor and an actuator for controlling the damper blade. The airflow controller has a control panel for displaying the measurement values and setting the operation parameters.
