CHAMBER DEPTH 14" - SENTRY 3-KEY CONTROLLER
Long lasting solid state relay
The Xpress-KM-14T 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 Xpress-KM-14T includes a mechanical relay as part of a safety circuit.Choose a side swing door or a drop door
You can order a Paragon knifemaking furnace with either a drop door or a 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.
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.
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 KM furnaces.
Choose from the optional paint colors
As shown in the photos, the standard knifemaking furnaces are painted a deep black. You can choose a different paint color at no extra charge.
Solid furnace construction
The furnace is insulated with 3” thick refractory firebrick, which is 1/2” thicker than the standard. The elements are mounted in dropped, recessed grooves machined into the firebrick. This groove protects the element for long life and low maintenance. Elements are simple to replace because they can be lifted directly from the groove. You can replace elements following instructions in the printed manual. 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.
Optional Knife Makers Heat Treating Kit
Contains 1 pair hot gloves, 1 heat treating fork, 4 knifeholders, and 8 knifeholder supports. You will need the kit if you remove all the blades together. If you remove them individually with tongs, you will need only the hot gloves and the knifeholders.
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 blades 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 factory-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.
