VAV BOX TSS / TSL – JOHNSON CONTROLS

Model TSS/TSL terminals provide variable air volume (VAV) control beyond the typical single duct box. They are specifically designed for precise air delivery throughout the entire operating 
range, regardless of the installed inlet conditions. They also offer improved space comfort and flexibility for a wide variety of HVAC applications.TSS/TSL terminals take advantage of typical benefits provided by single duct units, while performing at extremely low sound levels. This is critical in today’s buildings, where occupants are placing more emphasis on indoor acoustics.
The TSS/TSL terminal provides the ultimate in airflow control with the patented FlowStar TM
 airflow sensor. No other sensor in the industry can match the FlowStar’s ability to quietly and precisely measure airflow. Accurate airflow measurement is the basis for airflow control.
