Dry ice makers create a controlled environment for packed items being transported. Sending the liquid carbon dioxide (liquid CO2) through an expansion valve, temperatures drop to yield large volumes of dry ice blocks or pellets in an empty chamber. Available in compact designs that easily attach to liquid carbon dioxide cylinders, dry ice machines create cooling agents that are colder than typical water ice and will not leave residue.
