PA1651The 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.
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.
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.
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
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.
Every PARAGON KM18 Pro is handcrafted in Mesquite, Texas with pride, precision, and a commitment to bladesmiths who expect more from their tools. Built for performance. Designed for professionals. Trusted worldwide.
