The TruTemp™ Box Furnaces are an excellent solution to heat treat a wide variety of materials, from welded fabrications and forgings, to spun products and plates. Processes include tempering, hardening, normalizing, annealing, preheating and stress relieving.
Economical operation is achieved with superior thermal process engineering practices that apply state-of-the-art insulation material, airflow management, and custom programming.
Overview
Box Furnaces process products one at a time or in a single group at temperatures over 1100°F (592°C).
A Box Furnace features a vertical lift or swing out door allowing the various sized product(s) to be placed in the furnace. Box Furnaces are utilized for heat-treating, calcining, curing, annealing, stress relieving, preheating, tempering, and other high temperature thermal processes. Multiple zone heating technology can be integrated to maintain exceptional part temperature uniformity, and achieve ramp/soak heating and cooling profiles.
The TruTemp™ Box Furnace has many established design features, such as vertical lift doors, energy efficient insulation, fully proportional gas and electric heat, heavy duty cast hearth and piers and state-of-the art control packages.
The TruTemp™ Box Furnace has standard designs to 2250°F and can be customized for each individual application up to 3300°F. In addition, all furnaces are available with optional inert gas and recirculation systems.
Each Industrial Furnace project undergoes a comprehensive evaluation of every production requirement. The assessment includes areas such as production goals, part configuration and construction, part mass, temperature profile, and facility location or elevation.
The TruTemp Box Furnace offers high-temperature, heat treating up to 2250 degrees. Box furnaces are an excellent choice when space is at a premium. ITS can design custom box furnaces for applications up to 3300 degrees.
