Do not rank plates by outside dimensions or melting point alone. First verify what conditions the technical sheet's capacity value describes, then check how that value relates to your target product and temperature band.

Calculate the set that fits the container rather than one plate: record usable count by model, layout, rail fit, and total weight. Equal volume can still hide differences in internal geometry or product specification, so do not assume equivalence.

For a trial, keep load, route duration, initial conditions, and product-temperature measurement points consistent. Store manufacturer-sheet values and field measurements in separate columns; approve the set only when both support the choice.
