Cambro Granite Green 110 Voltage Heated Pan Carrier Insulated Food Server, 18 1/8 x 24 7/9 x 26 3/8 inch -- 1 each.If you need to hold hot food for more than 4 hours or if you need to frequently access food to replenish your chafing dishes, then our H-Series (Heated-Series) carriers are exactly what you need. We have gone a step beyond our original insulated carriers (as if they haven't already been doing a fantastic job as is) and added energy-efficient heaters to the doors. Food stays hot and safe for as long as needed and resets to safe temps within 3 minutes. Stays cool to the touch even when plugged in. Uses less energy than 3 standard 100 watt light bulbs. Holds 4 -4 inch deep food pans.
