Phase Change Materials

Phase Change Material (PCM )

Phase Change Material (PCM) absorbs and releases thermal energy during melting and freezing, to perfectly maintain the required product storage temperature for the duration of transportation. Heat or cold entering the container is absorbed by the PCM during the phase transition from solid to liquid and vice versa resulting in a minimum performance of 120 hours. Water has a melting point of 0°C. Using paraffin or salts our PCM is designed to melt and freeze within specific temperature ranges from -50 to +25 degrees.

Unlike water-based gel packs our innovative PCM technology allows one container configuration for all seasons, climates and hemispheres.

PCM is classified as a not dangerous materials according to the CLP-decree No. 1272/2008 by the European Chemicals Bureau.

Unlike electrical containers that rely on the availability of a power source half-way through the journey to recharge and allow for ongoing temperature stability, the performance of our advanced passive containers can be extended by reducing the difference between internal and external temperatures.

Self Recovery

Self-Recovery Effect

The impact of extreme ambient temperatures on our containers is delayed and reduced. When the container is placed in a high ambient temperature and is then moved to a low ambient temperature the internal temperature will immediately stabilize before starting to decrease after six to eight hours. This self-recovery effect is produced by the vacuum insulation in combination with the phase change materials inside the container. The effect can be used to establish transportation contingency measures that can extend shipment duration indefinitely. Our standard validations do not use the self-recovery effect as this would increase the performance duration endlessly.
