Eutectics and insulation16 / 26

GEBHARDT lists two body sizes under separate codes. Match to the container; fit does not prove capacity or hold time.

Yellow 0047068 (-14°C) and green 6081958 (-18°C) share a GEBHARDT body size. Plate colour and phase point are not cargo temperature.

GEBHARDT lists 0074699 at a -21°C phase point in a 480×280×34 mm body. This is not a cargo setpoint; validate the load separately.

Do not confuse plate phase point with product target. Check exact article code, placement and measured product conditions.

Before interpreting a curve, verify the model, load, ambient conditions, sensor location and test method.

Sublimation is the kind of phase change that goes straight from solid to gas, which is how dry ice is used up. A eutectic plate works between solid and liquid at a chosen melting point and is frozen again.

The ambient-to-interior difference affects heat transfer; hold time may not change linearly. Record shade, wind and load.

Compare quotes by lambda, panel U-value, complete-body performance and matched test conditions, then request the holding-hours protocol in writing.

Simple curve models explain behaviour; they do not guarantee duration. Record sensor location and conditions with the actual load.

A quote gives thickness in centimetres, but the result of insulation is measured by the K coefficient. How K differs from lambda and panel U, how it is used, and what to look for in a report.

Separate quality observations from safety decisions for frozen food; follow labels, records and authorized procedures.

Measure order volume, door access, handling steps and load distribution. Compare container sizes on the real route with a sample load.

Do not assume a savings percentage. Compare purchase, energy, labour, loss and actual usage over the same period.

There is no universal top-or-bottom rule. Check rails, clearances and sensor map against model instructions.

Colour or appearance alone is not enough. Match plate code and phase-change data to the intended product.

Cold air sinks, warmed air rises, corners sit closer to the outside and every lid opening upsets the balance. One reading cannot describe the whole container; the worst point is found by mapping.
