Go deep with Evenheat's KF Extreme Series Ovens. Our KF Extreme models are available in depths from 31.5" all the way up to 49.5". They feature dual doors and share the side-element-only design of the LB Series for phenomenal temperature distribution. Users include sword makers, volume knife and heat treaters, Damascus steel makers and anyone needing lots of real estate. The KF Extreme's are standard equipped with our Quiet Drive Solid State Relay and a variety of control choice options. We offer the KF Extreme models in 5 depths: 31.5", 36", 40.5, 45"and 49.5".
Features:
Chamber Depths from 31.5" to 49.5"
The KF Extreme Series are designed for long work such as Damascus steel production, firearm parts and of course swords and beyond. Chamber depths start at 31.5" and go all the way to 49.5" in 4.5" increments.
Side-Only Heating Elements
KF Extreme models are designed with side-only heating elements. This is the same design that is used in our LB Series that provides excellent temperature distribution along the entire length of the chamber.
Dual Side Opening Doors
The extra deep chambers of the KF Extreme's require the use of dual doors, front and back.
Cool Touch Handles
The handles/latches on our swing out doors are conveniently located at the front of the door, not hidden along the side. These spring loaded, phenolic handles are cool to the touch, one-handed in design and serve as the door latches as well.
Door Shields
The HT'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.
Relay Access Port
All KF Extreme models incorporate our 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 absolutely simple and effective and all it takes is a screwdriver! It's a given that mechanical relays will fail at some point. This relay access port really comes in handy when they do.
Door Shields
The KF Extreme's feature door shields to provide protection against firebrick damage as well as to reduce the temperature seen at the doors and door handles.
Swing View Equipped
Our TAP II and Rampmaster temperature controls are fitted to 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 your shop. It's that simple. The swing view pairs well with touchscreen controls like the TAP II as viewing angle can be perfectly aligned. You'll love it.
Quiet Drive Solid State Relay
All KF Extreme models are standard equipped with our Quiet Drive Solid State Relays. Our 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.
Firebrick Construction
Like all our heat treat ovens, KF Extreme 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 our optional Loud Alarm. Enjoy 80db of irritating alarm bliss and never miss another quench.
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 literally tear apart and open any welded or stuck contacts - true safety!
2200°F Maximum Temperature
The maximum usable temperature for the KF Extreme 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. This maximum temperature is limited by the heating element wire used. We use a Sandvik Nickel-Chrome alloy wire for all KF Extreme model heating elements. This alloy has proven to last, it tends to stay put and generally plays very nice when used at temps below 2200°F.
Maintenance Parts Tag
To assist you in replacing worn items we have included a maintenance parts tag indicating the proper Evenheat part numbers for anticipated maintenance items. Wish we had this decades ago.
Strong Stand and Tool Rests
Stands are strong and include a tool rest at each end. Cool!
Controller Options:
Rampmaster III - 12 Key Controller
The Rampmaster 3 is built from Bartlett Instruments V6-CF platform and is designed primarily for glass work but works well for other applications including heat treating. The Rampmaster 3 features dedicated buttons and readout and is offered to those who don't want a touchscreen. As with all of our controls the Rampmaster 3 is paired with a low-error, Special Limits thermocouple for very precise temperature sensing. Match it up with our Quiet Drive Solid State relay system and treat yourself to some serious performance with an old-school vibe. For detailed information on the Rampmaster 3 (V6-CF) visit Bartlett Instruments at bartinst.com. Note that the Rampmaster 3 does not support the Bartlett mobile App.
Icon - Touchscreen Controller
The Icon is built around Bartlett's Spark platform and brings touchscreen design to the market at a lower price point. The Icon / Spark was rigorously field-tested by Bartlett, Evenheat and others over the latter course of 2023. Programming was found to be clean and simple. User interaction with the display was deemed excellent. As expected the Icon paired well with our Quiet Drive Solid State relay system and performed beautifully. As with all Evenheat control designs, the Icon adds to an existing control platform with improvements like low-error, Special Limits thermocouples for precise temperature sensing and non-metallic faceplates for excellent Wi-Fi reception for the Bartlett mobile App. The Icon brings outstanding performance and value to the marketplace.
Tap II - Touchscreen Controller
The TAP II with its large screen, well laid out format and incredible mobile App is our most popular temperature controller. Firing schedule creation and use are simply simple. The science behind the screen delivers accurate and consistent results especially when matched with our Quiet Drive Solid State relay system. The TAP II is fitted with low-error Special Limits thermocouples for extremely accurate temperature control as well as our non-metallic faceplates offering excellent Wi-Fi reception. Get the TAP, get the highest rated kiln control mobile App and get going.
