What a plate delivers within a working band

A eutectic plate gives up its cold at its melting point. How much of it the load can use depends on where that melting point sits against the band the product accepts.

Short answer

A plate gives up its cold at its melting point, so the same plate does not do the same job in every temperature band. When the melting point sits below the product's upper limit and above the temperature that damages it, most of the capacity is usable; the part outside the band is wasted. Send us the route and product limits and we obtain GEBHARDT's thermal analysis for you.

The brine filling of a eutectic plate absorbs heat as it melts, and the plate holds its melting point while it does. Two plates with the same total energy can therefore yield very different amounts in different bands: before counting kilojoules, look at where the melting point sits against the load's band.

For chilled goods a -3 °C plate works inside the band. A -21 °C plate puts the same load at risk of freezing, and most of its energy is spent outside the band the product needs. In a deep-frozen load it runs the other way: a -3 °C plate stays warmer than the product inside the box and warms the load instead of cooling it.

Three details are enough to choose a plate:

The lowest and highest temperature the product accepts
Transport time and outside temperature
The container model

Send them to Aris Makina. We obtain GEBHARDT's free thermal analysis and pass it on; it calculates the longest time before the load reaches its limit temperature.
