Circular CAV controller | 125 mm
Product description
Circular constant air volume (CAV) controller is a device used in HVAC systems to regulate the airflow in a circular duct while keeping a constant volume of air. The CAV controller achieves its function by adjusting the damper position within the circular duct. Comparing to mechanical CAV controllers, this motorised controller uses a motor to automatically adjust the position of the damper blade. Therefore, it is more precise and can be controlled remotely. The motorised damper has also a built-in differential pressure controller to control the motor and keep the differential pressure constant at the desired setpoint.
This CAV controller is compatible with 125 mm diameter standard air ducts and is powered by a 24 VDC (PoM) supply voltage. It has the ability to regulate airflows at velocities of 0 to 10 m/s. The setpoint, minimum and maximum damper blade position and all other settings can be adjusted via Modbus RTU communication.
To prevent the leakage of the air, the damper blade and enclosure must be airtight. Airtightness is a crucial feature of circular CAV controllers, as it can increase comfort, lower noise levels, and improve efficiency of the devices. This damper blade provides class 4 airtightness, and the enclosure's airtightness is classified as class D according to EN 1751.
Circular CAV controllers are used in a variety of applications such as hospitals, laboratories, and cleanrooms. They are a valuable tool for providing different amounts of airflow to different areas of a building.
