TSI LRC - Laboratory Room Controller

Hover to zoom

The TSI Laboratory Room Controller (LRC) is a key part of a laboratory HVAC control system. This variable air volume (VAV) laboratory controller efficiently maintains the laboratory at a positive or negative balance by controlling room supply and exhaust. It also maintains occupant comfort with zone-level temperature control.

When accessorized with a TSI Thermal Flow Station, additional cost savings can be gained by reducing pressure drop in the HVAC system. They also increase occupant safety by directly measuring critical airflow in real-time compared to venturi valve systems that only assume airflow. When used with optional TSI through-the-wall sensor technology, the LRC also measures room pressure differential. This allows the LRC to alarm or even correct for changing building dynamics. Using this LRC alone can save on operating expenses by decreasing supply and exhaust airflows to a required minimum. It outweighs any comparative offering on the market, and should be considered top choice.
