Atmospheric Gases
Atmospheric gases are the gases normally found in the air around us. They include air, argon, carbon dioxide, helium, nitrogen and oxygen. Of these gases argon, oxygen and nitrogen are produced primarily by the separation of air into its constituent components. This is normally achieved by reducing the temperature of the air until each component liquefies and can be taken away. Of the two other gases in this section carbon dioxide is produced as a by-product of several chemical processing procedures. Helium occurs naturally only in the earth’s crust where it has been trapped in non-porous rock pockets, in a similar way as oil is found.Food Chilling
Chilling needs vary significantly from one application to another. To ensure the best fit for your individual process flow, we have developed a variety of delivery systems and devices that bring the environmental and quality benefits of gaseous, liquid and solid (dry ice) cryogenic chilling agents to stationary and mobile applications. Our ACCU-CHILL™ in-line chilling system, for instance, injects liquid carbon dioxide (LIC) or nitrogen (LIN) directly into mixing or storage vessels for instant results. We also have FROSTCRUISE™ in-transit refrigeration solutions based on LIN. If you need to transport smaller quantities, our SNOWCOOL™ isothermal trolleys rely on dry ice (or CO2 snow) for flexible temperature control. Dry ice can also optimise chilling at your conveyor or packaging station with our Dri-Pack chilling solutions.Food Freezing
Our numerous freezers meet the needs of a variety of applications. Modern freezer designs use the latest control programs to increase efficiency while meeting stringent hygiene standards. Cryogenic freezing of food with liquid nitrogen (LIN) and carbon dioxide (LIC) is a well-established practice that relies on those gases’ extreme cold temperatures (–196°C or –320°F, in the case of liquid nitrogen) as they come into contact with food. In the case of liquid carbon dioxide, snow forms when the liquid expands. The snow then vaporizes on the product. The CRYOLINE® family of food chilling equipment meets these modern requirements.
