To start, the LB Series has an innovative design as the elements are only located on the sides of the oven. By removing the heating elements from the back, the ovens are able to maintain a more balanced temperature throughout the chamber. So, now you can utilize the entire depth of the oven, regardless of blade length.
The firebricks used in the LB firing chamber are held together using compressive force to form a single piece. They are not cemented together like traditional ovens. This construction technique allows individual firebrick to move independently of each other during the heating and cooling cycles which helps to eliminate breakage.
Another advantage is that solid state relays are standard issue on all LB Series ovens. Solid state relays can be triggered up to 60 times a second compared to a mechanical relay that is limited to about once every 10 seconds. This translates into very tight and responsive temperature control which is crucial when heat treating.
Finally, Evenheat has added two new features to the LB Series... a door guard and a heat trap. The door guard provides protection against firebrick damage as well as reduces the temperature seen at the door and door handle. While the heat trap is a raised machined surface on the door that works as an extra measure against heat loss.
The Evenheat LB Series is available in three sizes... LB 18, LB 22.5 and LB 27! So, if you currently heat treat long blades or would like an oven with excellent heat distribution all the way to the back wall... the LB Series is just for you!
