Drill eight (8) 13/32” holes on 15 ¾” diameter bolt circle in the cover to mount the assembly. Bolt the assembly to the cover. Important! Make sure that the fill cover is left on the drying hopper or air diffusor/air trap assembly at all times to prevent contamination of the material and ensure proper drying.
Chapter 4: Startup and Operation 4-1 Introduction Air is drawn through a permanent electrostatic, washable filter, by a centrifugal blower. The air is blown through the process heater box where it is heated to the appropriate drying temperature. The temperature is controlled by a solid-state temperature controller which includes a built-in process air safety to prevent material meltdown. Heated air is then directed either through an air diffusor assembly in an existing machine hopper or a drying hopper.
4-5 Drying Non-Hygroscopic Materials Non-hygroscopic materials retain surface moisture which has to be removed to ensure high product quality. Different materials require different times and temperatures to thoroughly dry. Recommended drying rates are listed in the figure below.
Chapter 5: Maintenance 5-1 Maintaining Blower Motors Models 60, 150, and 450 The Regenair Centrifugal Blowers are virtually maintenance-free with prelubricated bearings. Model 1000, 1250, & 1500 The motor is self-lubricated for normal bearing life. For longest life, relubricate bearings annually. Remove drain plug. Inject good quality NLGI Grade 2 grease into fill hole. Run motor to discharge excess grease. Replace plug. Do not overgrease.
4. Quickly lower the process temperature set point by the number of degrees of separation you want. (Example: 25˚, from 200˚ to 175˚) 5. Turn the safety set point separation adjustment until the second pilot light on the controller changes state. The second pilot light will illuminate just below the safety set point. 5-5 Replacing the Heater Element The best quality industrial heaters are used in the air heater compartment.
Chapter 6: Troubleshooting Problem Possible Cause Possible Remedy Little or no air coming from process. Dirty air filters. Clean or replace filters. Suction in delivery tube. Phase is reversed on power drop coming into the dryer. Stop the dryer. If the dryer was connected to the drying hopper, verify that no material has been sucked into the heater can.
