Jan 23, 2003 Head Pressure Controllers sense refrigerant temperatures and modulate condenser fan speed to balance high to low side circuit vapor pressure. On start up, fan is given initial hard start at full speed for 10 seconds and then slows to speed to give required condensing temperature. As ambient temperatures fall further, fan gradually slows to about 1/3 full speed to maintain bearing lubrication and can be re-set to any desired level.
