Carbon dioxide (CO₂) is used as a cryogenic agent to remove heat, economically and precisely controlling the temperature of both the product and process for food chilling, cooling, and freezing applications and to preserve quality and shelf life when used for Modified Atmosphere Packaging (MAP). Food-grade CO₂ is used in carbonation of beverages and optimizes productivity in bottling and canning dispensing lines. CO₂ can be an effective way to increase growth and reduce crop damage in greenhouses and is an alternative to acids and chemicals in water treatment applications for pulp & paper mills, industrial operations, and municipal water treatment facilities. CO₂ is also commonly used as a shielding gas for Welding and Metals applications. Dry Ice, the solid form of CO₂ at temperature of -78.5˚C, is tasteless and odourless. It is used to address critical temperature control requirements during food packaging and provide refrigeration during transportation and distribution.
