Evenheat Heat Treat Oven - KO 22.5

Side-Only Element Design

The KO Series design was inspired, in part, by culinary bladesmiths who generally make long, thin 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 and improved the product.

​The front to back temperature distribution in the KO is incredibly even. Positioning in the chamber has no effect and the entire length can be used. The KO, with it's side-only element design, is the new standard!

Side Opening Door

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

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.

Relay Access Port

All KO models incorporate a Relay Access Port for simple, no-panel-off relay replacement. Simply
remove the access plate to gain access to the relay. There's no need to remove the control panel and dig into the internal wiring. It's simple and effective.

It's a given that mechanical relays will fail at some point. This relay access port really comes in handy when they do.

Door Shield

The KO'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.

Swing View Equipped

The TAP II and Rampmaster temperature controls are fitted to the 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.
 
The swing view pairs well with touchscreen controls like the TAP II as viewing angle can be perfectly aligned.

Firebrick Construction

Like all Evenheat heat treat ovens, LB models are built completely of firebrick. Firebrick has the desired characteristic of storing heat and then releasing it slowly and gently during the soak/hold portion of the
process. It's this particular quality that serves the heat treat process so well.

Loud Alarm Output Jack

A Loud Alarm output jack is included to connect the optional Loud Alarm. It reaches 80db of alarm sounds to never miss another quench.

2400°F Maximum Temperature

The maximum usable temperature for the KO models is 2400°F (1316°C). This maximum is well within the range for the vast majority of steels used by knife makers and machine shops.

Evenheat uses a Sandvik Iron based alloy wire for all KO model heating elements. This alloy has proven to last, it tends to stay in place and generally works satisfactory when used at temps below 2400°F.

Maintenance Parts Tag

To assist you in replacing worn items there is a maintenance parts tag included indicating the proper Evenheat part numbers for anticipated maintenance items.

Strong Stand and Tool Rest

Stands are strong and include a tool rest.

OPTIONS:

TAP II or Rampmaster Controls Option

KO models are available with your choice of the TAP II or Rampmaster temperature controllers. Check out the Controls tab for detailed descriptions of both controls.

Quiet Drive Solid State Relay Option

All KO models are available with a Quiet Drive Solid State Relay option. The Quiet Drive Solid State Relay System offers tight temperature control, high reliability and increased heating element life. The Quiet Drive is arguably the best designed and best performing solid state system on the market.

Power Interrupt Switch Option

The Power Interrupt Switch removes power from all heating elements as the door is opened and re-applies power as the door is closed. The switch used for this feature is a true safety switch and is designed specifically for safety applications. This safety switch will tear apart and open any welded or stuck contacts.

Why Upgrade from Mechanical Relays to Solid-State Relays?      

Mechanical Relays, which come standard on most kilns have internal moving parts which over time wear out and need to be replaced.  Kiln manufacturers recommend you replace your mechanical relays approximately every 2 years.  Solid-state relays have no moving parts and last far longer than standard mechanical relays and offer far better temperature control during hold times.  Since solid-state relays also have no moving parts to wear out, they NEVER need to be replaced.  You will notice that solid-state relays are silent.  The only sound you will hear is just the reassuring hum of the heating elements.  So, this factory upgrade saves you potential down time from having to wait for new relays to arrive, potential over-fires from relays sticking in the closed position, potential aggravation from having to learn how to remove and replace the mechanical relays yourself.  We think this upgrade is well worth the cost and will save you time and aggravation over the life of your kiln.
