Dry Ice Vs Gel Packs

However it doesn t last as long as many of the ice packs on the market and it will still leave you with a watery mess in the end.

Dry ice vs gel packs.

Deciding between dry ice and cold packs when choosing between dry ice and cold packs start by considering the temperature requirements for your shipment and the relative benefits of each approach. Dry ice is much colder maintaining a temperature of around 78 5 c 109 3 f as it sublimates and becomes co2 gas. Additionally the product that the gel pack is keeping cold will not get wet like it would with wet ice as the refrigerant gel is sealed into a plastic pouch. Because dry ice turns into co2 gas and not water there is no secondary waste.

If you are handling frozen products with dry ice be sure to follow all safety precautions. Just store the packs in the freezer until needed. For dry ice you can expect to use 5 to 10 pounds of dry ice for a 15 quart container for 24 hours. Start by filling up the pack with 3 5 cups of cold water and use an iron to seal it shut.

If you are shipping larger volumes simply multiply the amount of coolant by these ratios. It keeps ice colder longer so it doesn t melt as quickly. With the four pack of 9 5 x 10 inch pouches you ll be eliminating about 12 pounds of ice. This means that they freeze and thaw at roughly the same temperature as water would around 0 c 32 f.

Dry ice is safer for the environment. Keep coolant and product separate. Typically dry ice will keep products frozen longer than gel packs. Old methods include gel packs or dry ice.

Typical ice packs are water and polymer gel based or in the case of bricks saturated floral foam and then sealed in poly bags. Dry ice is hideously expensive and hard to locate. With most injuries involving the back gel packs are easy to use. Gel packs like k lock synthetic gel packs are water based.

The cooler shock dry cooler gel pack is a re usable ice pack that can be stocked in coolers over and over. Ice bags are better for ankles and knees for a longer cold period. Dry ice is actually carbon dioxide it s what you breathe out when you exhale and it s what makes soda fizzy. Techni ice made in austrailia is now available.

For gel packs it is recommended you use one pound of gel packs for each cubic foot for every 24 hours. Dry ice is made from recycled co2 and does not add to the greenhouse effect. The advances made by techni ice are truly amazing. Dry ice can be more cost effective.

Being a single item also gives gel packs the advantages of ease of use and storage with the added benefit of being reusable if so desired. Most ice packs and bricks have a phase change point around 0 c or 32 f which would be the temperature point where the material transitions from a solid to a liquid or vice versa.
