812 / 814 / 816 Series
Head Pressure Controls

The electronic head pressure control modulates condenser fan motor speed by varying the air volume through the condenser. The control monitors the head pressure by sensing the sub-cooled liquid line temperature.

Applications

Typically utilized on air-cooled condenser fan motors in air conditioning  and refrigeration systems.
