4. For the inert atmosphere ovens,
adjust flow rate.
a. Determine the desired
oxygen level.
b. Use the following chart to
determine the time to
achieve the desired oxygen
level.
NOTE: When operating the oven without
the optional water cooling, the minimum
operating temperature is approximately
78 C (nitrogen models) and
approximately 20 C (non-nitrogen
models) over the ambient room
temperature. This is the result of the
heat generated by the recirculating fan.
NOTE: This graph is an approximate measure.
Actual conditions will vary. The grade of the inlet
gas used will also affect performance.
