The Coldmaster 3-gallon ice cream server keeps ice cream cold for up to 8 hours (when charged overnight) without the need for messy and inconvenient ice baths. Simply freeze the unit overnight to charge the refrigerant gel. The gel is surrounded by layers of extra insulation to keep your ice cream cold longer. The portability makes this ice cream server ideal for use in ice cream sundae bars at schools, churches, weddings and more. The unit holds a standard sized 3-gallon ice cream tub. It includes a clear polycarbonate lid to protect the contents and assist in retaining temperature.
