Paragon has just introduced two new knife making furnaces... the KM-18T Pro 3 Zone and KM-36T Pro 3 Zone! These two heat treating furnaces are fully stocked with all the great Paragon features including 3-zone temperature control, solid state relays, and a digital Sentinel smart touch controller.
Both the KM-18T Pro 3 Zone and KM-36T Pro 3 Zone are insulated with 2 1/2” ceramic fiber and have the thermocouple wire inside the case for protection from the harsh environment of the typical bladesmith shop. Additionally, because of the ceramic fiber chamber, these ovens have a slightly larger interior space than the traditional KM Series.

Solid State Relays - Three solid state relays are mounted to aluminum heat sinks. SSR's last far longer than standard mechanical relays and offer better temperature control during holds.SSR's also have no moving parts to wear out. You will also notice is that SSR's are silent. The only sound you will hear just the reassuring hum of the heating elements.
3-Zone Temperature Control - Precise heat distribution throughout the length of the firing chamber. This is because it is divided into three zones. Each zone has its own thermocouple or temperature sensor. The Sentinel controller electronically adjusts the temperature of each zone. See for yourself--test for temperature uniformity by taking measurements along the length of a blade with a Rockwell Hardness Tester.
“Special Limit” Thermocouples - The thermocouples are made of 14-gauge exposed-tip for fast response to temperature changes. Measured from the front, the thermocouples are located in the top at 3”, 9”, and 15”.
Ceramic Fiber Firing Chamber - Unusually fast because it is made with a ceramic fiber firing chamber. It can reach 500°F in minutes. Long lasting, “wavy” elements in the walls are surface-mounted to dissipate heat rapidly and prolong element life.
Digital Sentinel Smart Touch Controller - Store 12 custom heat treating programs with up to 32 segments per program. (Adjust the rate, temperature, and hold time for each segment.) The Sentinel includes Novice Mode, which adds questions to guide you during programming. The Sentinel can also turn a vent or gas injection flow meter on or off for each segment of a program.
Choose a Guillotine Door, Drop Door, or Side-Swing Door - You can order with a stainless steel drop door, a side-swing door, or a guillotine door. The guillotine door lifts out of the way with one-handed operation with the assistance of a spring on each side of the furnace.
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.
So, if you are looking for a new heat treat oven with solid furnace construction... check out the KM-18T Pro 3 Zone and the KM-36T Pro 3 Zone from Paragon! I think you will like them as much as we do!
