​​In 1976, Marshall Air Systems, Inc. organized to design ventilation systems for the restaurant industry. Responding to a customer request, Marshall designed an electric conveyor hamburger broiler to automate the cooking process producing a consistently cooked, better tasting burger. A later request for improved and consistent food warming equipment resulted in the patented ThermoGlo™ technology, producing a consistent and superior heat source for holding foods hotter. Now Marshall manufactures a complete line of commercial foodservice equipment including Autobroil™conveyor broilers, Autotoast™ conveyor toasters, Autogrill™tortilla grills, ThermoGlo™ food warmers, heated holding units, and heated dump stations to complement its signature line of custom ventilation systems.
