This standard space saving dual chamber metal heat treat furnaces feature two furnace chambers on top of each other with different temperatures. The two chambers allow for immediate tempering or drawing after quench without waiting for the hardening chamber to cool down to the lower temperature required for tempering or drawing.

Options include quench tank, inert gas atmosphere to reduce scaling, AMS 2750E instrumention type D or CQI-9 package for NADCAP certification, bench stands and various temperature controllers. Contact our multi-lingual speaking specialists for any questions you might have.

Keith Company also builds custom electric or fuel gas fired (direct or indirect fired) heat treat furnaces including drop bottom quench furnaces for heat treating non ferrous materials such as aluminum and magnesium.
The upper door (with the hardening chamber) rises vertically so the hot face is away from the operator when he opens the door, while the lower oven chamber door is a hinge type construction. For improved temperature uniformity during tempering and drawing, the lower furnace chamber can be equipped with a high temperature fan. Each furnace chamber has it's own independent temperature control, thermocouple and solid state relay for power switching.

A quench tank can be stored under the furnace and rolled out when needed. The wire wound heating elements are embedded into a ceramic plate which makes it easy to replace. Additional features such as inert protective atmosphere in each chamber to avoid scaling of your parts during heat treating are available; see Dual Chamber Bench Top Spec Sheet Other means to reduce scaling: parts wrapped in heat treat foil.
