Cress AE Dual-Chamber Heat-Treatment Furnace – Upper 2250 °F, Lower 1250 °F, 15″–48″ Chambers

Description

The Cress AE Dual-Chamber Furnace houses two independently controlled heat zones in one compact frame—perfect for streamlined quench-to-temper workflows. The upper chamber (15–48 in deep) reaches 2250 °F, while the lower chamber (15–43 in deep) tempers at 1250 °F.

Each zone includes digital programmable PID & high-limit safety controllers, dual door safety switches, solid-state relays, and emergency interlocks. The top chamber features a vertical lift door; the bottom has a side-swing door with a built-in air-circulation fan to maintain tight temperature gradients.

Built on a heavy-gauge steel frame with rope seals and alloy heating elements embedded in brick/perforated sidewall plates, the furnace allows immediate post-quench tempering without cooldown delay.

Available sizes include:

• AE1520D/PM4: 15″ × 20″ upper + 15″ × 15″ lower
• AE1824D: 18″ × 24″ upper + 18″ × 19″ lower
• AE1836D: 18″ × 36″ upper + 18″ × 31″ lower
• AE1848D: 18″ × 48″ upper + 18″ × 43″ lower

Power requirements scale from 18 kW to 41 kW; full details and dimensions in sheet. A built-in caster-mounted quench tank rounds out this integrated heat-treatment solution
