PARAGON KM45 Pro Double Barrel: Maximum Chamber, Elite Control

With a massive 13.25" wide, 5.25" high, and 45" deep chamber, this kiln is built for long swords, batch production, or any project that demands space, precision, and thermal speed. It’s the top-tier performer in the Pro Series—ready for your most ambitious heat treating challenges.

Why Have a Heat Treating Furnace in Your Shop?

Precision heat treating separates a good blade from a great one. With your own furnace, you're free to experiment, perfect, and repeat on your own terms. The KM45 Pro Double Barrel empowers makers with consistent thermal control, rapid cycling, and the confidence that comes from understanding every phase of the process. No outsourcing. No compromises.

Why Choose the PARAGON KM45 Pro Double Barrel?

This kiln combines the advanced features of the KM Pro Series with the largest internal capacity of any Double Barrel model. With 3-zone control, fast-reacting thermocouples, and surface-mounted elements, it delivers clean, even heat from front to back—every cycle.

• Interior chamber: 13.25" W x 5.25" H x 45" D (1.80 cubic feet)

• 3-Zone Temperature Control: Three exposed-tip thermocouples (front, center, rear) allow the SENTINEL controller to maintain even heat distribution across the full chamber length
