Thermcraft started doing business in January 1971 from a small warehouse space in downtown Winston-Salem, N.C. From that small startup operation, Thermcraft has progressively grown into an international manufacturer of thermal-processing equipment. The company offers industrial and laboratory furnaces, ovens, high-temperature heating elements, insulation and replacement parts. Thermcraft now resides in a 70,000-square-foot manufacturing and office space located just a few miles from its original location in Winston-Salem, where it all began 50 years ago.
Lucifer Furnaces completed a yearlong contract to deliver 18 AMS 2750-compliant furnaces and ovens to the United States Air Force. Models supplied include heavy-duty single-chamber furnaces, dual-chamber furnace/oven combinations, recirculating convection ovens and dual ovens. All models are designed and built to comply with AMS 2750 Class 2 (+/-10°F) and Class 5 (+/-25°F) specifications with instrumentation package D, which includes digital paperless recorder/controllers, high-limit safety systems and SCR power supplies. TUS and SAT access ports are built in for ongoing system accuracy tests and temperature uniformity survey compliance. All models are completely wired and temperature uniformity surveyed in-house prior to shipment.
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.
