Bulk Density
– Bulk density is the weight per unit
volume of the raw plastic material as it is received
from the material manufacturer. This parameter is
important to set to ensure proper performance of
the ULTRA-1000. Bulk density can be edited under
‘Advanced Info’.
***WARNING:
Without setting this parameter the
machine may not maximize its material throughput
and/or have a chance to overflow.
T1 Inlet Temp Setpoint
– This is heat hopper inlet
temperature. By the end of the
preheat
cycle time,
all material in the Heating Hopper will be heated to
this temperature. By default, the Setpoint
temperature is set to 150°F. Contact the material
manufacturer for temperature recommendations.
Preheat Time
– This is the duration of heating from
a cold start.
Vacuum Time
– This is the duration of a vacuum
and is what determines the cycle time. The default
vacuum time is 20 minutes. In the vast majority of
drying operations, this time is adequate and does
not need to be adjusted. Special circumstances
may require different vacuum times. Please consult
a Maguire Dryer Technical for additional
information.
Press the setpoint field to adjust the setting. Use
the on-screen keypad to enter the setpoint and
press the green check to complete the setting
adjustment
