NanoCool controlled temperature packaging uses an age-old cooling technique with a unique new approach. Using the principles of evaporative cooling, which creates a cooling effect by the evaporation of water, NanoCool controlled temperature packaging evaporates small quantities of water at low pressure continuously over hours and days of operation. At low pressures, such as with the NanoCool cooler, the evaporation of this small quantity of water is rapid and the cooling effect very powerful. Evaporation of water in a vacuum has seven times the cooling power compared to the melting of ice.

The cooling effect begins within a few seconds of pushing a button, which releases the flow of a small quantity of water within the low pressure environment of the NanoCool cooler and in five minutes the cooler is working to its potential. The flow of water is regulated within the cooler and responds to the ambient temperature the package is exposed to.

There are no gel packs involved, so you do not need to refrigerate or freeze anything in advance of the packout, so NanoCool controlled temperature packaging should be stored at warehouse temperatures.
