KF Series
The KF Series of heat treat ovens were developed for both private and business use. Operating from 240V, and reaching temperatures up to 2200°F, the KF models are well suited to heat treat the vast majority of steels common to knife makers and metal workers.
The KF Series heat treat ovens are the original design that has heating elements in the back wall. You'll also want to check out our LB Series which is designed with side-only heating elements.
The KF's are available in a variety of control choice options as well as the solid state output option (which you want).
See below for available models and check out the Features tab for in-depth details on all KF Series features.
