For cooling goods below freezing point, dry ice can be a solution. This is an extremely cold product, of no less than -78.5 degrees Celsius. An advantage of using dry ice is that you do not need electricity to transport below freezing point. Moreover, when evaporated, dry ice passes into the gaseous form, leaving no traces like melting water.
Dry ice can be used for various applications. It is particularly suitable for the refrigerated transport of, for example, pharmaceutical products and frozen food products. You can think of certain medicines and food that have to arrive at their destination in the frozen state. The gas of dry ice that remains when it evaporates/sublimates takes up about 550 times more space than dry ice in solid form. It is therefore important to use dry ice in combination with a well-insulating but gas-permeable packaging. For example an EPS box or EcoCoolBox.
