PARAGON KM18 Pro: Power, Precision, and Pro Performance

The PARAGON KM18 Pro is a professional-grade heat treating kiln built for bladesmiths who need a longer chamber and more refined thermal control. With its 18" depth, ceramic fiber insulation, and 3-zone temperature management, the KM18 Pro delivers uniform heating, fast ramp times, and dependable results—cycle after cycle.

Why Have a Heat Treating Furnace in Your Shop?

Owning your own furnace isn’t just about convenience—it’s about control. Whether you're working with complex steels, developing your own quench recipes, or chasing tighter tolerances on Rockwell hardness, the KM18 Pro gives you the tools to experiment, refine, and repeat with precision.

Why Choose the PARAGON KM18 Pro?

The KM18 Pro combines advanced control, professional reliability, and smart design in a mid-sized format. Its chamber offers ample room for longer blades while maintaining tight thermal uniformity across the entire firing zone. The ceramic fiber body heats up quickly, saves energy, and cools down fast for back-to-back cycles.

  • Interior chamber: 5.5" W x 4.3" H x 18" D (0.25 cubic feet)

  • 3-Zone Temperature Control: Three thermocouples placed along the chamber length allow the SENTINEL controller to manage each zone independently—ensuring balanced heating and accurate soak temperatures.

  • Special Limit Thermocouples: Exposed-tip, 14-gauge sensors provide fast thermal response and higher precision than standard types.

  • Solid-State Relays: Silent, efficient, and long-lasting. All SSRs are mounted on aluminum heat sinks and paired with a backup safety relay.

  • 2.5” Ceramic Fiber Insulation: Lightweight and fast-heating for reduced cycle time and energy savings.

  • Surface-Mounted Elements: Wall-mounted wavy elements distribute heat evenly and allow easy replacement.

  • Guillotine Door: Spring-assisted, vertical-opening door lifts up and away from the user—keeping the hot face safely distanced and freeing up space around the kiln.

  • Steel case with built-in stand: Heavy-duty construction that holds up in any workshop setting.

Who is This Furnace For?

The KM18 Pro is ideal for:

  • Bladesmiths working with long or complex blades

  • Professionals needing precise multi-zone control for consistent hardening

  • Knife shops moving into production-level output

  • Schools and labs requiring fast, accurate, and repeatable thermal cycles

Optional Upgrades

  • Gas Injection Flow Meter: Inject argon or other inert gases to reduce scale and oxidation. Available as a retrofit kit or installed.

  • Add a solenoid valve: Automates gas flow—delivers only when active in your firing program.

  • Knifemaking Heat Treating Kit: Includes blade holders, supports, gloves, and a 31" fork for safe, efficient handling.

Get a Gas Injection Flow Meter (GIFM) and Solenoid Kit


Achieving a clean, scale-free blade finish during heat treatment isn’t just about aesthetics—it’s about quality, consistency, and minimizing post-processing time. The Gas Injection Flow Meter (GIFM) is a trusted tool among professional bladesmiths and heat treaters for precisely that reason.


Minimize Scale, Maximize Results

During high-temperature heat treating, oxygen in the kiln chamber reacts with the steel surface, producing unwanted oxidation scale. Traditionally, this has been mitigated using stainless steel foil wrap—a solution that works, but comes with added cost, time, and waste.


With the GIFM installed, you can introduce an inert gas like argon or nitrogen directly into the firing chamber. This displaces oxygen and significantly reduces oxidation, helping you:

  • Eliminate or reduce the need for stainless foil

  • Retain sharper blade edges and crisper grind lines

  • Improve consistency in finish and minimize cleanup

  • Create a cleaner working environment

Precise Control and Automation with the Optional Solenoid Kit
Take control even further with the Solenoid Valve Kit, which works in tandem with the GIFM. This upgrade lets you:

  • Automate gas flow by turning it on/off at specific stages of the firing process (per segment)

  • Ensure gas is flowing only when needed—saving resources and increasing safety

  • Achieve repeatable, precision-controlled atmospheres in your heat treating cycles

Perfect for advanced users and production settings, this upgrade transforms your kiln into a highly efficient and customizable heat treating system.


Trusted by Professionals

This system has been field-proven by bladesmiths, metalworkers, and heat treatment professionals who demand the best finish and tightest process control.


 

Whether you’re eliminating scale on high-carbon steel or refining your results with stainless alloys, the GIFM with optional solenoid valve gives you an edge—literally and figuratively.
