120V North American Operation
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 Option
All KH models are available with our optional 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.
We have more to tell you about our solid state relay, our design choices and why you should choose the solid state option. Just click below.
Multiple Control Options
Evenheat works closely with control manufacturers SDS Industries and Bartlett Instruments to bring you the best in performance, features and programming ease.
The KH Series models are available with the very popular TAP touchscreen control by SDS Industries as well as the Rampmaster 3 and Set-Pro by Bartlett Instrument.

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!
