A device that produces solid carbon dioxide utilizes liquid CO2 from a pressurized tank or cylinder. This solidified gas, reaching temperatures as low as -78.5C (-109.3F), finds applications in various fields, from preserving perishable goods during transportation to creating special effects in theatrical productions. A simple example is its use in keeping ice cream frozen during delivery without the need for conventional refrigeration.
Offering convenient on-site production eliminates the logistical challenges and costs associated with procuring and storing dry ice from external vendors. This capability is particularly valuable for businesses with consistent or high-volume needs. Historically, accessing this essential substance often required specialized suppliers and careful handling due to its extreme temperature. Modern devices streamline this process, ensuring a readily available supply for a range of purposes, including medical and scientific applications.
