The Intermetro RPC13-055 Food Warmer Element 120V 700W produces heat within compatible commercial food warming equipment. When electrical power reaches the heating element, resistance within the element converts electrical energy into heat, raising the temperature of the surrounding warming area. Its placement inside the warmer allows heat to transfer to the food-holding compartment during operation. This component is used in restaurants, cafeterias, catering operations, and other foodservice settings where prepared food is maintained at serving temperature. Compatibility should be verified against the specific warmer model before installation or replacement.
