  • Page 2: Hm Dryers

    HM DRYERS FEATURES: The HM series dryers are a fully assembled dryer and hopper combination where the dryer is mounted on the hopper to be positioned on top of molding machines. They are ideal where floor space is not available and material changes are infrequent. The HM dryer series utilize the ARID-X dual bed design that provides a constant supply of dry air to the material hopper.
  • Page 3 ADC Advanced Dryer Controls The ARID-X series can be supplied with the Advanced Dryer Control (ADC). The new ADC (Advanced Dryer Control) was introduced for optimum operation of the dryer and is as user friendly as possible. The easy-to-see alphanumeric display indicates all operating parameters and leads the operator through a menu driven program for all settings and information.

  • Page 22: Temperature Setback Theory

    dryer will shut down and an error will be displayed. This condition can occur upon installation or when moved within the plant. TEMPERATURE SETBACK THEORY The optional temperature setback feature for the ADC control prevents over drying of the material due to excessive residence in a drying hopper at the suggested drying temperatures. This is especially true for Nylon, which can be over dried leading to degradation of the resin resulting in molding problems and brittle parts.
  • Page 23 Setback Display Selection of the setback option is shown on the main screen by an asterisk * prior to the hopper number. Parenthesis around the setpoint temperature indicates the temperature has been setback. The setback temperature is then displayed.
