PARAGON KM18 Pro Double Barrel: Wide, Fast, and Fully Controlled
The PARAGON KM18 Pro Double Barrel offers expanded capacity for serious bladesmiths who need more room—without sacrificing performance. With its wide chamber, this kiln combines speed, uniformity, and flexibility in one powerful, workshop-ready package.
Why Have a Heat Treating Furnace in Your Shop?
With your own kiln, you're no longer limited by guesswork or turnaround times. The KM18 Pro Double Barrel allows you to heat treat wider blades, multi-piece batches, or oversized tooling with complete confidence. From rapid heat-up to fine-tuned multi-zone control, this kiln makes your workshop more capable—and your results more consistent.
Why Choose the PARAGON KM18 Pro Double Barrel?
The KM18 Pro Double Barrel is engineered for professionals who want maximum performance in a broader workspace. The expanded chamber profile gives you greater freedom when working with cleavers, large chef knives, or batch setups—while the ceramic fiber body and 3-zone control deliver speed and precision in every cycle.
3-Zone Temperature Control: Three exposed-tip thermocouples allow the SENTINEL controller to manage each section of the chamber independently—ensuring uniform temperatures throughout.
Special Limit Thermocouples: Fast-response, 14-gauge thermocouples for tight, real-time thermal feedback.
Solid-State Relays: Quiet and long-lasting, with three SSRs mounted on aluminum heat sinks and backed by a safety relay.
2.5” Ceramic Fiber Insulation: Lightweight construction speeds up heat-up and cool-down times for more efficient workflows.
Surface-Mounted “Wavy” Elements: Broad heat coverage and long element life thanks to wall-mounted design.
Guillotine Door: The spring-assisted, vertically opening door lifts smoothly and keeps the hot side away from the user—ideal for tight workspaces.
Heavy-duty steel case with integrated stand: Durable and stable for serious shop use.
Who is This Furnace For?
The KM18 Pro Double Barrel is ideal for:
Bladesmiths making wide-profile blades, cleavers, machetes, or curved knives
Professionals heat treating multiple pieces or using jigs and fixtures
Knife shops moving into batch production with varied geometries
Labs and training centers needing fast, even, multi-zone performance
Optional Upgrades
Gas Injection Flow Meter: Displace oxygen inside the chamber with argon or another inert gas to minimize scaling.
Add a solenoid valve: Automates and secures gas flow—delivers only when activated in your firing program.
