Dry ice removes almost twice as much heat per pound as water ice and has the added advantage of changing directly from a solid to a gas without ever becoming a liquid – hence the term “dry ice.” It is ideal for a variety of cooling uses, and its inert carbon dioxide gas is an excellent preservative. Compared to water ice, dry ice not only offers far greater cooling capabilities, dry ice also maintains its degree of effective cooling for many hours after water ice has become non-functional and simply melted away. However, if water ice is a necessity, such as in a cooler, dry ice may be used in combination with water ice to extend the life of the water ice.

Dry ice is used in poultry, red meat and sausage plants to retard heat build-up, as well as prevent water weight loss during shipment. In the bakery industry it is used to mix ingredients, eliminate moisture and to keep yeast from working until the appropriate time.

Dry ice is used in a number of commercial applications including airline catering, the manufacture of golf balls and fire extinguishers, flash freezing in the rubber industry, absorbing ammonia refrigeration leaks and creating fog for the entertainment industry. It is extensively used in the manufacturing of plastics, chemicals, beverages, pharmaceuticals, metals and many other products. Dry ice is also important to mining, construction, and a variety of laboratory and medical applications.

HOW TO USE
1: For Freezing - Place dry ice on top of items to be frozen. If freezing trophy game, do not allow direct contact with trophy. Superficial or freezer burn damage may result.

2: For Cooling - Place dry ice in bottom of cooler, cover with wet ice or insulating material, then place items to be kept cold on top. Do not allow direct contact with dry ice.

3: For Special Effects - Use gloves to place small amounts of dry ice in hot water for fog. Use approximately 15 lbs per hour.

4: Other Uses for Dry Ice -

  • Fresh Meat Processing & Shipping
  • Deflashing Molded Rubber & Plastic
  • Low Temperature Testing
  • Industrial Cleaning (Dry Ice Pellet Blasting)
  • Freeze Branding
  • Carbonating Beverages
  • Shrink Fitting
  • Water Well Treating
  • Inerting & Purging
Note: Store dry ice in an insulated cooler – do not place in working refrigerator or freezer.
