4-8 Setting the Shift on Dew Point

Our dehumidifying dryers shift air flow from the on-line desiccant bed to the regenerated desiccant bed, based on actual dew point demand, not fixed time cycles. After the off-line bed regenerates, the PLC controller waits for a high dew point signal from the process air dew point controller before switching beds. The PLC controller has a four (4) -hour timer override if it does not receive a signal from the dew point control.

„Set the shift on dew point set point to the highest process air moisture content you want to allow before the dryer shifts air flow to the regenerated desiccant bed. The dew point controller is set at the factory for -20ºF (-29ºC).

„To change the dew point setting, press the Up Arrow and Down Arrow buttons to the shift point you want.
