Use the material acceptance endpoint to compare equipment configurations; confirm each capability on the selected model.
Compare BVO and NVO through the actual model's fan, vacuum and nitrogen operating modes. For batch trays, verify uniformity with circulation; for powders, films or dust-prone loads, also check airflow disturbance.
Accept oxygen level, time to reach it and hold-stage stability separately; record nitrogen purity, supply pressure and consumption.
Define the oxygen sampling location, analyser delay and calibration method. Test with a real load and after door opening; supply-gas purity cannot substitute for chamber oxygen measurements.
Confirm the sequence of evacuation, nitrogen admission and heating, and whether the circulation fan can operate in vacuum mode. Screen pressure-sensitive samples on a small load first.
Check oxidation and moisture regain during cooling and unloading, together with exhaust routing, gas-supply failure response and site ventilation.
Record the initial sample condition, loading layout, recipe version and raw measurements. Agree the acceptance endpoint before the trial; repeat at challenging load positions and compare the finished material result.
Candidate models in the current catalogue: ESC-BVO1000-T6, ESC-BVO125-T6, ESC-BVO216-T6, ESC-BVO343-T6. These are comparison candidates, subject to the process checks above.
The following specifications apply only to the models listed:
