Siemens Building Technology 546-00493 43" Horizontal Uni-Trak Top Assembly

The Siemens Building Technology 546-00493 Horizontal Uni-Trak Top Assembly is used in the HVAC systems for accurate control of variable air volume terminal units. It is a part that is capable of sensing and controlling the flow of air as per the need of the system. Variable air volume control sensors cover a 43-inch range and control the position of the dampers to regulate airflow. This top assembly, when integrated with a VAV HVAC system, provides the desired conditional control with minimum energy usage. These include better quality of air indoors, better comfort, and better performance of the systems with a low need for maintenance.
