 Keith multi-stack furnaces provide exceptional temperature uniformity during heating and cooling for processes that require precise temperature control to 1565C/2850F.
This design has proven to be highly effective for firing advanced ceramics, electronic components, nanomaterials, and a wide range of temperature-sensitive products.
The load is divided into multiple stacks separated by heating elements in the furnace chamber.
Several standard models are offered, and larger custom sizes, different hearth configurations, and higher temperature ratings are also available.

General Construction
Keith multi-stack furnaces are primarily insulated with high quality, low mass ceramic fiber insulation for energy efficiency and improved heating/cooling control. Two load cars are supplied that roll on track extending on two opposing sides when the elevator is fully lowered. The cars are raised and lowered on a heavy-duty motor driven electrically operated lifting mechanism.
 Heating and Cooling Systems
In addition to dividing the load with heating elements between stacks, temperature is often controlled using vertical control zones as well. This is particularly useful for processes that require rapid and uniform heating and cooling. A variety of optional forced and controlled draft air-cooling systems are available from Keith that deliver precise and repeatable performance.
Automated Furance Control
Digital process controls are standard on all Keith furnaces. Everything from programmable heating and cooling, venting of process volatiles, and all safety logic is managed automatically using the latest control technology. Integrated communications with a remote supervisory workstation and data logging are popular options.
