Paragon Double Barrel 18T Heat Treating Furnace

Long lasting solid state relay

The Double Barrel 18T now has a solid state relay, which lasts far longer than 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 18T includes a mechanical relay as part of a safety circuit.

The Paragon Double Barrel 18T is just the right size for heat treating and case hardening gun parts and knives. Experiment with color base hardening. Restore the faded colors of historic guns. As with the other Paragon furnaces, the Double Barrel 18T has a digital controller so you can program the exact temperature and hold time needed.

The controller eliminates guesswork. Instead of estimating a temperature by the color of the heat, just program a temperature. 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).

  • Choose a side swing door or a drop door

    You can order a Paragon Double Barrel 18T heat treating furnace with either a drop door or a side-swing door. The photo above shows the traditional drop door. We will verify your choice by telephone after your purchase. The price of the furnace is the same with either door style.

    The drop door opens downward with one-handed operation. A counter-weight handle holds the door securely closed. The door, whether drop or side-swing, is mounted on a heavy-duty 1/2” thick hinge shaft for smooth opening. Because of the rigid case and heavy hinge, the door is sturdy enough for years of faithful service.

    Optional Gas Injection Flow Meter

    During heat treating, scale forms on the surface of the steel. One way to eliminate most scaling is to wrap the steel in stainless steel foil. Another way is to install the gas injection flow meter on your furnace. It is available as either an add-on kit, or you can order the furnace with the meter installed.

    The meter regulates the flow of an inert gas, such as argon, inside the furnace. The gas displaces the oxygen to prevent most scaling.

    Please remember that results with the flow meter vary depending on the type of inert gas you use and your level of experience.


    Choose from the optional paint colors

    As shown in the photos, the standard knifemaking furnaces are painted a deep black, which would look perfect in your shop. You can choose a different paint color at no extra charge.

  • Door safety switch

    The door micro safety switch shuts off the power to the elements when the door is opened, yet the controller continues to give a temperature readout. The safety switch is standard on Paragon Double Barrel furnaces.

    Superior heat distribution

    To improve the heat distribution in the Double Barrel 18T, 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.

    Printed instruction manuals

    Your furnace includes a wiring diagram, a controller instruction manual, and a heat treating manual with heat treating instructions for D2, 440C, ATS 34 and 154 CM. The manuals are written in plain English for the beginner.

    Thermocouple with “special limit” wire

    The thermocouple senses temperature inside the kiln. It is the small rod that extends into the firing chamber. The ¼” wide Type-K, 14-gauge, exposed-tip thermocouple is made with special-limit wire for superior accuracy. The exposed tip gives the controller a fast response time for even temperatures during holds. The thermocouple is made in America to our exacting standards.
