Dry Ice Machines
In order to keep the fog on the ground, the emitted fog must be cooled. This can be done with ground fog machines with ice, dry ice or a cooling unit. The cooled fog stays on the ground longer due to the thermal effect. If the ground fog is generated with a dry ice machine, the chemical reaction of dry ice with hot water is used. Dry ice (-75 C°) is flushed with hot water and thus quickly melted. As a result, the dry ice converts to the CO2 gas state and creates a fog that glides away from the ground.
