Wisconsin Oven received an order for a standard draw batch (SDB) oven from a manufacturer of aerospace products. The electrically heated oven, which has been shipped, will be used for processing parts in a reduced-oxygen atmosphere utilizing nitrogen. The oven has a maximum continuous operating temperature of 1400°F (760°C), and it has the capability to operate at 230°F (110°C) above ambient. The qualified work-zone dimensions are 24 inches wide x 24 inches high x 48 inches deep, and the overall chamber dimensions are 36 inches wide x 36 inches high x 60 inches deep.
A medical technology manufacturer ordered Despatch conveyor ovens to help produce COVID-19 diagnostic testing systems. Perforated plenums above the belt create a laminar flow that will keep the small, lightweight parts from being disturbed. Fresh-air ports were added to support the positive chamber pressure needed to achieve the required temperature uniformity of ±9°F (±5°C). The continuous belt design is suited for large quantities of similar workpieces being processed.
Wisconsin Oven shipped two indirect-fired, two-zone conveyor ovens that will heat composite materials used in the manufacturing process of electric utility equipment. The first work-zone chamber has dimensions of 35 feet wide x 6 feet, 4 inches long x 4 feet, 2 inches high. The second work-zone camber has work dimensions of 35 feet wide x 12 feet, 4 inches long x 4 feet, 2 inches high. The ovens can heat 10,240 pounds of composite materials. There is one profile opening at each end of the oven for entrance and exit of materials, and each oven is equipped with two industrial tube-fired burners.

Fuel-train systems, or “valve safety trains,” are designed to safely deliver fuel to burners for the heating of boilers, dryers, process ovens, thermal oxidizers or other fuel-fired industrial equipment.
Wisconsin Oven shipped a continuous-duty conveyor oven to a U.S. manufacturer that will use it for stress relieving steel snap rings used in automotive parts. The natural-gas-fired oven has a maximum operating temperature of 650°F and a work zone measuring 2 feet, 2 inches wide x 10 feet long x 1 foot high. When preheated, the oven has sufficient capability to heat 350 pounds of steel parts per hour from 70°F to 550°F. Heated air will be delivered in a horizontal airflow configuration through a fully adjustable boxed duct located along the length and across the height of the work chamber.
