Unlike conventional ice packs, the NU-ICE Commercial Series Packs are capable of maintaining a sub-zero temperature in a freezer or other insulated environment for an extended period of time. Safe, environmentally friendly, and reusable for up to five years, they are a great alternative to gas emitting dry ice, and require no special handling, training or costly haz-mat shipping fees.
Simply charge the pack by freezing it to initiate the chemical reaction in the pack. The pack immediately begins to absorb energy (heat) and emit sub-zero temperatures once environment temperatures begin to rise. These packs provide superior performance to traditional gel-packs that are water based and have a much sharper temperature discharge rate.
