As a group of friends (Scientist, Chemist, Nurse, Engineer) prior to starting CoolerShock, we often wondered why all of those ice alternative products such as Blue Ice and ice packs never did the job. With all the advances in our society, how is that we could not come up with an ice alternative for coolers?
Some of us went fishing and would buy 10's of pounds of ice for the all day trip out and back. We bought the best coolers (Yeti for us). Others on the team would go boating and buy 15-20 pounds of ice, fill the cooler with warm sodas and beer and always hope for the best. We would be thoroughly disappointed. Yes we were always happy to be boating or tailgating or having a party but the stuff in the cooler always disappointed. Beers and Soda were okay, the food was fine at first but would later be floating around in murky water and was always ruined by the end of the day.
So we decided to research the problem and try to solve it. We connected with a friend who was working on a cooling product for the transportation of blood. We came to understand all the principals involved, and not only helped with the development of the blood transport product, we also developed a product that works great in coolers.
So what's the issue with current alternatives? Many of them are just not designed with a large coolers in mind. The basic things to take into consideration is mass (the size of the ice pack) and the temperature it gives off when it’s doing the heavy cooling (Phase Change).
We developed a product with mass and density that is non-toxic. It worked so well for the blood product that we had to split the pack in two and create two separate cooling chambers and temperature ranges. We now offer the full CoolerShock for rapid cooling, and the split pack CoolerShock for measured cooling over time. Of course you can determine how much cooling you want or need by the amount of CoolerShock you place in a cooler as well.
These are all re-usable packs. I want to point out that you need a similar amount by weight as you do ice so 15lbs of ice would be 3 CoolerShock’s. The difference is that things will be really cold and completely dry. In case you haven’t seen the instructions, they should be cooled 24-48 hours at Zero degrees Fahrenheit. This gets them fully charged. Most freezers can do zero, you just have to be sure the dial is at its lowest settings. This is often the recommended temperature for your freezer.
