CO2ler: Cooler Uses Compressed CO2 Gas

💍 Must see geeky jewelry


Meet the CO2ler: a cooler for your food and drinks that relies on compressed CO2 gas to get the job done. When liquified gas is forced through the expansion valve, it causes a rapid change in pressure. The gas cools as it goes through condenser coils, allowing you to keep your food fresh and drinks cold. The device uses a standard CO2 tank, which you can refill at any sporting goods store. It can hold up to 24 cans or 12 bottles. It also features wheels and handles for easy transportation. You can find it on Quirky.
