2.0 INSTALLATION
NDB Dryers can be mounted directly to the processing machine. Secure with bracing as required
to stabilize the unit. Convenient lugs are located at the end and on the valve box for this purpose.
Others may be used if necessary.
The NDB can also be mounted on a floor stand next to the dryer. The floor stand (P/N SCR-FS-
004) is supplied with a Vacuum Takeoff Box, a 1.5” probe and 5” casters. Dried material can be
transferred to the process machine with a Machine Mount Loader.
Connect power to the dryer according to the nameplate, which is located on the frame or
control box of the dryer.
Connect the required electrical power according to plant, local and state electrical
codes and regulations. Electrical installation should only be performed by a qualified
electrician.
3.0 DESCRIPTION OF OPERATION
NDB dryers are designed to be a simple, compact and easy to use for drying of plastics in
cases where the throughput is 50 lb./hr. or less.
Moist air is drawn from the drying hopper by the blower assembly and it
is directed through the valve assembly and into one of the desiccant beds. Moisture is
adsorbed by the desiccant and the dry, low dew point air is blown across the process heater,
heated to the desired temperature, and discharged from the dryer. A small portion of this air is
diverted back through the second desiccant bed instead of traveling through the process
heater. This air is heated by the regeneration heater, which is buried in the desiccant bed. The
hot air regenerates the desiccant and carries away the moisture through the regeneration air
exhaust port.
At the end of the regeneration heating cycle, the regeneration heater is shut down but the dry
purge air continues to flow. This helps to carry some of the excess heat of regeneration away
from the desiccant bed, allowing it to cool in preparation for the adsorption cycle.
At the end of the timed 4-hour adsorption period a simple shift of the solenoid valve causes the
diverter valve to change position. The freshly regenerated bed now begins adsorbing moisture
and the other bed is regenerated. Just one blower (the process blower) is required for both the
process and regeneration functions and it runs continuously when the dryer is on.

NDB-15-50 IM 28 FEB 2018 © 2018 NOVATEC, Inc. All Rights Reserved Page 6
4.0 INITIAL START- UP PROCEDURE
Fill the hopper completely with material and adjust the temperature
controller to 60º F. Push the on/off switch to the “ON” position and check the blower for proper
rotation by observing the rotation of the motor at the end facing the control box. The proper
rotation is indicated by an arrow on the blower housing.
Allow the unit to dry-cycle for 24 hours with the hopper filled with material before operating. This
will allow the moisture adsorbed by the desiccant during transit or inactivity to be discharged.
Failure to dry cycle the unit may cause drying problems with the material. It is necessaryto have
material in the hopper in order for the regeneration cycle to function properly.
5.0 OPERATING PROCEDURE
After the initial start-up period, adjust the temperature controller to the drying temperature
necessary for the material to be dried. Dry the plastic pellets for the required residence period,
which is generally two to six hours depending on the material.
After the residence period is complete, the material is dry and ready for processing. As dry
material is withdrawn from the bottom, additional material should be added to the hopper at the
same rate. (NOTE: It is extremely important to keep the hopper as full as possible for proper
drying.)

6.0 MONITORING PLC CYCLE
•Press ESC button on the Mini PLC
•Press the ⇓arrow to the Set Param line.
•Press OK button. Main counter B1 should display with Cnt value at bottom of the screen
•Cnt value represents current count in minutes for the total cycle. If counter B1 fails to display,
press ⇓or ⇑arrows until B1 displays with Cnt value.
•To fast cycle advance counter B1 connect the 115V hot wire to PLC input I2.
•Check schematic diagram for wires numbers to jump for fast cycle advance. Each
1 minute count becomes 1 second in the fast advance mode.
•On initial start fast advance B1 counter to 0 or 1 counter value. Reference the chart below for
sequence of operation.
