 These popular high quality furnaces have been industry's choice since 1960. The many design updates ensure that you get the most current, proven, refractory and electrical design features that modern technology can provide. When you compare there will be no question that Keith's dual furnaces represent the best value available for high quality industrial production.
Two independently operated furnaces are assembled into a single attractive floor space saving package. Several models even have room in the base for an optional pull-out quench tank. This combination of capabilities provides you with the ability to heat treat, harden, quench, anneal, temper, reheat, and more all in a single system.
The usual configuration is a 2250F top chamber for hardening and a 1250F lower chamber forwith a circulating fan for tempering or drawing. Thus, there is no waiting for the heat treat furnace to cool down. Alternatively both furnaces can be either high temperature or low temperature.

Special Features
Heating Elements
In the smaller models, heavy coiled wire heating elements are installed in grooved refractory plates, which slip into grooves in the refractory lining. The plates protect the heating elements from damage while loading and unloading the furnace and provide exceptional support for the elements for long element life. In larger furnaces, the heating elements are installed in grooves within the ceramic fiber lining.
Controls
All furnace controls are conveniently located in a side mounted control cabinet at a level where they are easy to view and operate. Solid-state digital indicating PID temperature controllers are used for the most precise control of temperature. All controllers are equipped with broken thermocouple protection.
Protection from Oxidation
 Several approaches are available when parts need to be protected from oxygen in the upper chamber. The easiest method is to wrap your parts in stainless steel heat-treating foil. A small amount of paper or charcoal can be included to consume the oxygen in the package. Likewise, you can place your parts into an alloy box containing paper or charcoal. Another approach is to insert an atmosphere of argon or nitrogen into the furnace with our optional inert atmosphere package. This eliminates most of the oxygen in the furnace, and is suitable for processing many grades of alloy.
