Eutectics and insulation13 / 26

An energy label alone does not determine transport duration. Assess product conditions, load and route records alongside the plate documentation.

Colour or phase point alone does not identify a plate's contents or concentration. Match the product code and data sheet before ordering.

However much salt you add to water, the freezing point stops falling at a certain place. For sodium chloride that floor is about -21.2 °C, and the coldest eutectic plate sits just above it.

Do not infer performance from application method alone; review test and repair documents for the exact construction.

Match material and spare-part compatibility to product code and technical drawing; track damage with records.

Do not infer layer materials from a model-family name. Match the selected configuration to its product sheet, section details and care instructions.

A lid can freeze to its gasket when a container stands closed in a frozen regime. The source is moisture in the air: each kilogram of 30 °C air at 60% humidity leaves about 15 grams of water at -20 °C; forcing the lid damages the seal.

Verify article compatibility from records; check fit and movement without forcing.

On GEBHARDT plates the closure colour, size and article number recover the melting point; if the three do not agree, the plate stays out of use.

A loose catch and a worn gasket give the same symptom. The ISO 815-1 formula and a four-step decision order tell the two apart.

Do not select a new plate by phase point or appearance alone. Verify dimensions, edge, freezing equipment and use procedure for the exact model.

Appearance does not prove rail or holder dimensions. Document interfaces before ordering and safely trial a sample on the exact model.

A shelf and plate layout does not guarantee two independent temperature bands in one container. Assess suitability with a real-load route measurement.

Rack compatibility with a blast freezer depends on dimensions, airflow and approved use. Determine freezing time by trial.

Record damage, leakage or performance differences; decide using model instructions and controlled comparison.

Check container and plate dimensions separately; match racks, holders and freezer capacity by article.
