A device categorized as a portable fogger employs solid carbon dioxide to create a thick, white fog effect. These machines are often used in theatrical productions, special events, and other entertainment applications to generate a low-lying fog that quickly dissipates without leaving residue. Typically, such a device features a water reservoir that is heated, into which dry ice pellets are added. The resulting combination of warm water and dry ice produces a dense fog.
The advantage of this type of fog effect lies in its density, rapid dissipation, and lack of residue. Unlike fog machines that use glycol-based fluids, the fog produced by this method does not linger in the air or leave a sticky residue on surfaces. This characteristic makes it suitable for environments where a dramatic, yet temporary, fog effect is desired. The portability of these units further enhances their utility, allowing for easy transport and setup in various locations. Over time, these machines have become increasingly popular due to their practicality and the visually appealing effects they create. They offer a safer alternative to some older fog production methods while delivering a comparable, if not superior, aesthetic.
