DIBY

Diby's patented technology uses layered carbon dioxide to create an impressive thermal barrier around dry ice which makes it last longer and simultaneously regulates the temperature inside your cooler. Either increasing or decreasing the layers changes the heat transfer behavior.

Because carbon dioxide gas uncontained is an extremely poor thermal conductor, adding or subtracting the DIBY refrigerator sleeve creates either refrigerator temperatures or freezer temperatures. It's as simple as that.
