Pusher Furnace

The pusher furnace is a continuous furnace concept that allows processing of small and large product in trays and baskets. The hearth consists of a series of steel, alloy or ceramic skid type supports. For support of heavy loads, alloy rollers can be incorporated into the hearth or onto the trays to reduce the pushing forces required. Furnaces can be provided in electric, direct fired and indirect gas fired configurations to meet specific processing requirements.
