Cress Dual Chamber Industrial Furnace - 2500°F Hardening / 1250°F Tempering - 18" Depth

1992 Cress C122012DK High-Temp Dual-Chamber Furnace

2500°F Hardening | 1250°F Draw | 460V 3-Phase | S/N 9207

Available for immediate acquisition is this Cress C122012DK, a professional-grade dual-chamber electric furnace. This "DK" model is uniquely upgraded for ultra-high temperature operations, reaching 2500°F—well above the standard 2250°F found on base models. This makes it an essential asset for shops hardening high-speed steels (M-series) and other advanced alloys.

Key Features & Advantages

• Dual-Zone Efficiency: Perform hardening in the upper chamber and tempering in the lower chamber simultaneously, drastically reducing turnaround time for tool-and-die projects.
• Premium Insulation: Built with 4-1/2" of high-quality insulating firebrick backed by 2" of 1800°F block insulation for rapid heat-up and maximum energy retention.
• Advanced "DK" Spec: Unlike standard 220V hobbyist units, this 460V 3-phase machine is built for continuous industrial duty and high-torque thermal cycles.
• Precision Controls: Equipped with digital microprocessor-based controllers and solid-state relays for chatter-free, precise temperature maintenance.
• Safety Integrated: Dual door-actuated safety switches automatically disconnect power to the heating elements and fan motor when the doors are opened.
• Operator Focused: Counter-balanced upper door opens up and away from the operator, keeping the "hot side" of the door directed away from the face and arms.
