Eutectics and insulation26 / 26

A tonne of broccoli gives off about 890 W at 20 °C and 62 W at 0 °C. Respiration heat by commodity from USDA data, the conversion factor and a worked example.

Age alone does not show container performance. Track damage and compare a suspect unit with a sound reference under matched conditions.

Turn current product and vaccination-program instructions into measurable acceptance clauses.

GEBHARDT's Isotec TBX with eutectic plates keeps the cold chain intact for up to 24 hours. The real time on a route depends on plate type, goods, fill level, pre-cooling and door openings; the plate itself is ready after 15-21 hours in the freezer.

Compare PCM options by phase temperature, capacity, cycling and compatibility data, not broad claims of superiority.

For GEBHARDT plates the freezer runs at least 5 °C below the melting point, air stays free between plates, and a set leaves only when the filling is solid.

It can: an insulated container, eutectic plates with the right melting point fully frozen in the warehouse, and food loaded at transport temperature. The duration is calculated from route and load data.

Pick one cost line and compare like-for-like trips. Track energy and empty returns while keeping the temperature target intact.

Check product, container and eutectic-plate preparation separately, and see how starting temperature and load quantity affect the transport plan.

Choose by product requirements, route, supply and preparation capacity. Trial both arrangements with the same load and compare your records.

Wall thickness alone does not show heat loss. Inspect joints such as corners, hinges and seals, and measure with a temperature difference.

Hold time depends on starting conditions, plate layout, fill and openings. Measure your acceptance curve on the longest route.
