The Paragon Double Barrel 9T is just the right size for heat treating and case hardening gun parts and knives. It is especially popular for pocket knives. Experiment with color base hardening. Restore the faded colors of historic guns. As with the other Paragon furnaces, the Double Barrel 9T 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).
Long lasting solid state relay
The Double Barrel 9T 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 9T includes a mechanical relay as part of a safety circuit.
Choose a side swing door or a drop door
You can order a Paragon Double Barrel 9T heat treating furnace with either a drop door or a side-swing door. (The photo above shows the traditional drop door. Scroll down to Options to see the side swing door.) 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.
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.
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. For more details, click on the link in the Options section below.
