The
graphs below represent the furnaces's fast heating and cooling
rate with the new element
The
Table below compares the new element's profile to our standard
element. The table shows the deviation of axial temperature
from the center of the furnace (10") to the last four inches
at each end. The controller was set at various settings to
show the consistency of the profiles.

All data was collected from the same 2
1/2" x 20" (57mm x 510mm) furnace. Only the element
was changed. The profiles are representative; however,
each furnace will vary.
