Evenheat Heat Treat Oven - KH418

Inside Dimensions: 18" Deep x 6.5" Wide x 4.25" High - 0.29 Cubic Feet Exterior Dimensions: 23.5" Deep x 16.5" Wide x 17.25" High (includes the 8" stand) For North American heat treaters who can't get access to 240V, the KH Series is made just for you. KH Series heat treat ovens are designed to operate from the North American standard household voltage of 120V. The KH Series models are very capable of reaching temperature, however they will take about twice as long to get there than a 240V model. Generally speaking they will reach 1650°F in about 1-1/2 hours. 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 KH'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. 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. Many thanks to those who have offered feedback on our door handle/latch. We have updated the design to make centering, inserting and all-around operation cleaner and easier! Quiet Drive Solid State Relay It's the job of the relay to turn the heating elements On and Off. A solid state relay can do so up to 120 times per second which allows for incredible temperature control. It also does so without the given, eventual failure of a mechanical relay. We fully expect our solid state relay to last the life of the unit. Evenheat's Quiet Drive Solid State Relay System does away with the mechanical relays traditionally used in kilns and replaces them with solid state relays. Traditional, mechanical relays wear out and fail at some point. They have to and they always will. Not so with the solid state. Solid state means there are no moving parts, nothing to wear out and nothing to replace. Solid state also means superior heating element operation resulting in tighter temperature control, longer element life and enhanced performance. TAP Touchscreen Smart Controller by SDS Industries The TAP is our most popular temperature controller: its wonderfully simple operation, excellent control capability and well laid-out touchscreen just rock. Nowhere is simple-use more evident than in the single touch needed to access your ceramic firing schedules. Just touch the Start key and all of your schedules are immediately displayed for selection. Schedules are displayed in full, easy to read text. The TAP comes preloaded with multiple ceramic firing schedules as well as virtually unlimited space for your custom schedules. Creating your custom ceramic firing schedules is easy and relaxed. The TAP walks you through the process with on-screen displays and text that are easily understood and followed. Once created, your schedules stay as long as you want them. Temperature control is tight and on the mark. Overshoot and ripple are kept to a bare minimum, particularly when coupled with our Quiet Drive Solid State output. Consistency is not an issue as the TAP performs reliably time after time. Relay Access Port All KH 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. Power Interrupt Switch 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! Loud Alarm Output Jack KH models are standard equipped with a Loud Alarm Output Jack for use with our Loud Alarm Option. All of our controls feature an audible alarm. These alarms let you know when you've reached temperature, and more importantly, when it's time to quench. These alarms however, aren't really loud enough to break through the noise found in a working shop. In response, we've included an alarm output jack on the bottom of the control enclosure that allows you to plug in our Loud Alarm (sold separately). Just plug it in and enjoy 80db of irritating alarm bliss. Door Shield The KH'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 KH 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. KH models feature a side-element-only design borrowed from our stellar LB Series models. Swing View Control Enclosure All temperature controls, except for the Set-Pro, 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. You'll love it. Strong Stand and Tool Rest The stands of the KH's have been upgraded to a stronger design and include a tool rest.
