Keeping food cold with electricity entails many drawbacks. For example, a traditional refrigerated case lets out as much cold air as an open refrigerator. This is expensive energy in terms of both money and environmental resources. Phase Coolers are thin sheets with a unique ability to stay cold for many hours. They work in all environments and can easily be taken out or put away as needed. This is a major advantage for buffets and when transporting food.
This is a much better option when compared to buckets of ice on a buffet line or in a cooler. It is better looking and keeps food at the proper temperature.
