Evenheat Heat Treat Oven - LB 27


Inside Dimensions: 10" W x 6.5" H x 27" D
Exterior Dimensions: 20" W x 19.5" H x 34.5" D

The LB Series side-element-only design was inspired by culinary and long-blade makers as well as the knife making community as a whole. Knife makers needed to use the entire length of the chamber without overheating their blades at the back wall. Evenheat took a fresh look at our designs and created the side-only heating element LB Series.

The results are incredible: front to back temperature distribution is dead-nut. Whether you're making culinary, tactical, fixed blades, folders, doing gun work or something else entirely, the LB Series sets the new standard!

The LB Series represents the ultimate mix of bladesmith input and Evenheat design. As the predecessor of the KF Series, which was a top-seller in the knife-making market, the LB is quite simply the finest heat treat oven on the planet!

Side-Only Element Design

The LB Series design was inspired, in part, by culinary bladesmiths who generally make long, thin blades blades. These bladesmiths needed to use the entire length of the chamber without overheating their blades at the back wall. Evenheat took a fresh look, got rid of the rear wall heating element, and nailed it.

The front to back temperature distribution in the LB is incredibly even. Positioning in the chamber has no effect and the entire length can be used.

Side Opening Door

Heat treating requires the removing of some very hot material from the chamber in order to quench. Everything in the chamber is hot, which includes the door. The doors on the LB's swing out and to the side, a full 180° if you need it. This puts the super-heated door well away from you as you concentrate on the work at hand.

The side opening door is an excellent design choice and makes all the difference.

Cool Touch Handle

The handle/latch on our swing out door is conveniently located at the front of the door, not hidden along the side. This spring loaded, phenolic handle is cool to the touch, is one-handed in design and serves as the door latch as well.

Door Shield

The LB's feature a door shield to provide protection against firebrick damage as well as to reduce the temperature seen at the door and door handle.

2200°F (1204°C) Maximum Temperature

The maximum usable temperature for the LB models is 2200°F (1204°C). This maximum is well within the range for the vast majority of steels used by knife makers and machine shops.

Swing View Control Enclosure

All temperature controls used on the LB's are fitted into our Swing View Adjustable Enclosure.

The Swing View is a pivoting, swing-up enclosure that allows you to rotate the control to a comfortable viewing and programming angle. Once you're done, lay it back down to see it from across the shop. It's that simple. The swing view pairs well with TAP touchscreen control as viewing angle can be perfectly aligned.

Strong Stand and Tool Rest

The LB's feature our updated stand design that delivers a strong, supportive base and tool rest

Quiet Drive Solid State Relay

Evenheat's patented Quiet Drive Solid State Relay is hands down the best investment you can make in your kiln!

With no moving parts, this relay is able to be triggered up to 60 times a second as opposed to the upper limit of 10 times a second on the default mechanical relay. This means incredibly tight temperature control ensuring each and every one of your firings is as accurate as possible.

The Quiet Drive uses a special method call "Zero Crossing" that will ensure that the heating elements are off when the voltage is at 0V - Giving your heating elements a break so that they will last longer, and you'll save energy. Since there are no moving parts - the Quiet Drive Solid State relay should never need replacing! You will save money and time by never needing to worry about this in the future.

MK Blade Fixture

A necessity for all knife makers! The MK 1 and MK 2 Blade Fixtures are used to hold your knives in place during heat treating.

The MK 2 will hold 6 blades and is designed for the Evenheat KO, KF, and LB series. It will not fit the KH models.

Power Interrupt Switch / Automatic Lid Shutoff

The power interrupt switch is a useful safety feature which removes power from the heating elements of your kiln once it is opened, and reapplies the power once the lid has been closed. If you believe you'd ever like to open the kiln during firing, the power interrupt switch is a highly recommended addition to your new purchase.
