Product overview
The closer a shape gets to a sphere, the lower its surface-to-volume ratio — which is why a block sublimes far more slowly than the same weight in pellets. On long air-cargo lanes (Istanbul–Shanghai, Istanbul–Houston) blocks form the cold core of the ice load while pellets only fill the gaps.
HMA cuts blocks to the thickness you need: we grid them to your pallet geometry and build a single cold core inside the thermal blanket.
Where it is used
Intercontinental export
Works as the cold core under a thermal blanket on 96–120 hour air-cargo lanes.
Cold room back-up
An emergency cold battery that saves stock during a cold room failure or an inventory stop.
Industrial shrink fitting
A bed of slices for cooling parts homogeneously before interference fits.
Advantages
- Longest endurance per kilogram
- Up to 65% less sublimation together with a thermal blanket
- Custom slicing to your pallet geometry
- Export delivery with UN 1845 declaration
