8402-136 | LIMIT CONTROL LINE BRT | Bard HVAC

LIMIT CONTROL LINE BRT Control line is designed to control air flow from dampers and louvers on rooftop units. All of our dampers are airflow tested to make sure they are properly sized for the specified application. Limit control is a modulating control that uses a control signal to modulate the position of the damper. These controls can be implemented on either a normally open, normally closed or float configuration. In a normally closed application, the damper will be closed when the control signal is zero and will modulate open up to a fully open position as the control signal goes to 100%.
