The furnace shell is constructed with Wisconsin Oven’s patented, high efficiency Expandable Surface™ design. This design includes 6” of semi-rigid batt type insulation and a segmented sheet metal interior. The outer shell is made of 3/16” carbon steel plate and the inner shell and ductwork are 20 gauge aluminized steel. The annealing furnace has one vertical lift, electrically operated door with counterweight.   

The furnace heating system consists of four (4) tube-fired burners and a combustion blower. The recirculation system has a 39,000 CFM plug style blower and utilizes a combination airflow design to maximize heating rates and temperature uniformity.
