Before choosing operating conditions for scale-up from 27L to 216L, define the observable material result and the actual load.
For transfer from 27 L to 216 L, retain the laboratory sample curve and remeasure the complete larger-chamber cycle. Use these transfer or throughput checks as the trial objective. Retain laboratory material endpoints and sample curves; map tray area, spacing, layers and thermal load for comparison.
Map calibrated sample-temperature channels at challenging loading positions and record pressure or oxygen when used; synchronise the complete-cycle timing record.
Repeat the larger or changed loading with the actual material. Compare local endpoints with the laboratory reference and record loading, evacuation, heating, hold, cooling and unloading time.
Separate material-lot differences, loading obstruction and equipment drift. Base transfer or throughput decisions on accepted output and complete-cycle evidence, then retest any revised loading.
Describe scale-up using usable tray area, part layers, spacing and thermal load per batch; nominal-volume ratios do not directly predict throughput.
Retain the material endpoint and sample-temperature window from laboratory trials, and remeasure heating, evacuation, purge and cooling times in the larger chamber.
Compare lab and pilot results at the most challenging load positions, then assess accepted output per batch and complete cycle time.
A validation report should identify sensors and calibration, show raw curves and material results, and document deviations and the decision to accept or revise the process.
The catalogue does not establish a model match for this scope. Provide the material and acceptance requirements for engineering review.
For this comparison, request the current specification for the selected configuration and the test conditions for your actual load.
