Marvel's professional refrigerated drawers have a dynamic cooling technology that delivers rapid cool down and the industry's best temperature stability. By using the MARVEL Intuit integrated controls you can set a precise temperature between 34 and 42 degrees F, while the thermal-efficient cabinet ensures optimum food preservation and energy efficiency while maximizing capacity. Audio and visual signals alarm if the beverage center is accidentally left open, and the vacation/Sabbath mode conserves energy during times when the unit is not in use
