Medium Freezer Pak

Engel Medium Freezer Pak

Enjoy your recreational sports and outdoor activities without the mess of melted ice! 

Designed to outperform standard gel packs, the reusable Engel Freezer Pak makes for a great cooler companion to keep contents cold and dry. Works great in lunch boxes, beach coolers, soft sided coolers and cold shipping. It also works well to extend the life of traditional bagged ice. The Engel Cooler Pak is a non-toxic, non-hazardous, chemical freezer pack capable of maintaining a sub-zero temperature “charge” in a freezer or other insulated environment for an extended period of time. This is accomplished by charging the pack (freezing @ 20° F) to initiate the simple chemical reaction within the pack. The pack immediately begins to absorb energy (heat) and emit sub-zero temperatures once environment temperatures begin to rise.These packs are safe and environmentally friendly and can be re-used for up to five years.
