LT 22.5" Tempering Oven with Mid-Depth Chamber for Longer Blade Tempering
The Evenheat LT 22.5 Tempering Oven is designed to handle post-quench tempering cycles with precision. With a 22.5″ deep chamber and shallow profile, it provides the ideal environment for tempering long blades, chef knives, or shop tools after hardening.
Reaching up to 1200°F (650°C), the LT 22.5 ensures your steels achieve the toughness and durability needed for real-world use. Its compact design makes it efficient to run, while features like the Icon digital control, Quiet Drive SSR, and Power Interrupt Switch give you reliable, repeatable results every cycle.
Built to stack directly on LB, KO, and KF ovens of matching depth (or use as a standalone bench unit), the LT 22.5 saves space while expanding your shop’s heat-treating capability. It’s purpose-built to help you finish every blade strong.
