4-2 Process Air Dew Point Display

The Dew Point display indicates the current process air delivery moisture content. The display uses a microprocessor-based controller for reading dew point air temperature. The controller is a modular, self-contained removable unit in the mounting housing. All parameters are factory-set and adjusted; no field adjustment to the internal controls is necessary. The high dew point alarm is also factory adjusted.

4-3 Process Air Temperature Controller

Our dehumidifying dryers use a microprocessor-based PID temperature controller for maintaining process air temperature. The controller is a modular, self-contained unit you can remove from the mounting housing. All parameters except for the process air set point is factory set and adjusted; no field adjustment to the internal controls is necessary.
