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.
Wisconsin Oven Corp. shipped an indirect-gas-fired walk-in oven to a manufacturer in the technology industry. The heavy-duty oven, which will be used for heat treating materials used in the production of vehicle batteries, has work-chamber dimensions of 12 feet wide x 6 feet long x 10 feet, 6 inches high. Guaranteed temperature uniformity of ±10°F at 190°F was documented with a nine-point temperature uniformity survey in an empty oven chamber under static operating conditions.
Wisconsin Oven Corp. shipped an electrically heated, Ferris-wheel batch oven to the aerospace industry. It will be used to cure epoxy resins and varnishes on assorted aerospace parts. The oven, which has a maximum operating temperature of 500°F, has work-chamber dimensions of 3 feet, 4 inches wide x 3 feet, 6 inches long x 3 feet, 6 inches high. When the configuration of the workload is such that it is capable of absorbing the heat, the heavy-duty unit has sufficient capability to heat 200 pounds of product to the company’s specified temperature range within two hours.
Wisconsin Oven Corp. shipped a four-zone conveyor oven to a manufacturer in the oil-and-gas industry. The electrically heated oven has the capability to heat 25 parts per hour with a heating time of 48 minutes and a cooling time of 12 minutes. Each chamber in this four-zone oven has a maximum temperature rating of 752°F (400°C) and dimensions of 1 foot, 8 inches wide x 2 feet long x 6 inches high. According to Wisconsin Oven, the oven will be used to melt a high-temperature polymer into a U-shape ring that houses electronic components.
Dave Strand was hired by Wisconsin Oven Corp. as a shop worker in 1986. In 2019, he retires as president and CEO of Thermal Product Solutions, the parent company of Wisconsin Oven.

Wisconsin Oven Corp. shipped five electrically heated, standard draw batch (SDB) ovens to East Carolina Metal Treating in Raleigh, N.C. The ovens, which have a maximum operating temperature of 1250°F, will be used for stress relieving. The basket dimensions of each oven are 2 feet wide x 3 feet long x 2 feet high. Guaranteed temperature uniformity of ±10°F at setpoints 300°F, 750°F and 1250°F was documented with a nine-point temperature uniformity survey in empty oven chambers under static operating conditions.
Pyradia received an order from Uni-Cast for two electric drop-bottom ovens for its T4 applications. Uni-Cast, which manufactures aluminum investment castings, is expanding its factory in Londonderry, N.H. The ovens have a temperature uniformity of +/-10°F.
