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. Marshall’s high standards of quality and innovation are top priority goals. All product lines are supported by in-house Sales, Customer Service, and Engineering teams. Marshall’s manufacturing facility features technologically advanced fabrication equipment including fiber optic lasers and robots, guaranteeing consistent quality. Staffed with knowledgeable on-site personnel, our pledge is a courteous and prompt response for every customer in a timely manner. A toll free line, available 24 hours a day, 7 days a week, in addition to a network of service centers across the United States and international distributors around the world, ensures reliable field support.
