The Paragon KM54 Double Barrel Kiln is just the right size for every big job. As with the other Paragon furnaces, the Double Barrel has a digital controller so you can program the exact temperature and hold time that you need. 

The controller eliminates guesswork. Instead of estimating a temperature by the color of the heat, just enter a temperature into the controller. You will no longer have to adjust a switch to maintain the hold time for case hardening; the controller maintains the hold time for you. Set the hold time for as long as necessary (typically two hours). 

Long lasting solid-state relay

The Paragon Double Barrel Kiln KM54 has a solid-state relay, which far outlasts a standard mechanical relay. The solid-state relay has no moving parts to wear out. The first thing you will notice is that the solid-state relay is silent. You will hear just the reassuring hum of elements. The solid-state relay makes heating elements last longer and offers better temperature control during holds.

The Double Barrel KM54 includes a mechanical relay as part of a safety circuit.


Door safety switch
Both doors also include the door safety switch. The door micro safety switch shuts off the power to the elements when the door is opened, yet the temperature controller remains powered. The safety switch is standard on the Paragon Double Barrel kiln furnace.

Superior heat distribution

To improve the heat distribution in the Double Barrel KM54, we have added heating elements in the top and removed the heat from the back. The furnace now heats from three directions--the two sidewalls and the top for uniform heating.

Solid furnace construction

The furnace is insulated with 3” thick refractory firebrick, which is 1/2” thicker than the standard. The sidewall elements are mounted in dropped, recessed grooves machined into the firebrick. This groove protects the element for long life and low maintenance. The elements in the top are seated in pinless element grooves. The firing chamber is protected by a rigid steel case. A built-in solid stand lifts the firing chamber safely off your worktable. The thermocouple wire is kept inside the control box for protection from the harsh environment of the typical bladesmith shop.
