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.
