Damper Controls

• Modulates airflow to save energy and maintain close capacity control
• Pre-engineered system is easy to retrofit into any centrifugal fan unit
• End switch kits ensure proper operation on multiple shaft units

A modulating capacity control damper system is available for all BAC centrifugal fan evaporative cooling equipment. They are used when close control of the leaving fluid temperature is required and/or the unit will operate under varying loads and a variable frequency drive is not an option. Automatic control of the dampers can be achieved by installation of a BAC electric damper control package.

The damper control package consists of:

1. Damper actuator(s)
2. Damper actuator end switch kits
3. Temperature controller
4. Voltage transformer
