KH Features

Side Opening Door

Working in the heat is fun, trying to avoid it isn’t. Doors that swing down throw off massive amounts of heat just below the chamber entrance. Our side hinged doors swing out to the left to keep the heat away for more cool and comfortable use. It’s an excellent design choice that makes all the difference.
KH Features

Cool & Comfortable Door Handle


The handle 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.

KH Features

Full Stainless Jacket


Multi-section ovens are designed to lower production costs for the oven manufacturer. It's a worthy goal but it comes at the cost of oven quality. It’s a trade off we’re not willing to make. We build our KH ovens with full stainless jackets from front to back. Full jackets mean absolutely solid, life extending construction. There are no leaks, no shifting, no buckles and no weakness. Insist on Full Stainless Jackets for true build quality.
KH Features

Corner Mounting Technique


The corners of the oven body and door provide excellent strength for mounting. The flat sides of the oven don’t offer this strength. We install our load bearing hinge brackets on these corners for this very reason. Longer life, high reliability: solid design makes a difference.
KH Features

Power Interrupt Switch


All KH Series Ovens are stock equipped with the Power Interrupt (a.k.a. door switch). The Power Interrupt automatically removes power from all heating elements as the door is opened and reapplies power as the door is closed. The switch used for this feature is a true safety switch and is designed specifically for safety applications. The choice of this switch adds an additional level of safety and security not found in ordinary “safety” switches.
KH Features

Responsive Thermocouples


Our thermocouples (temperature sensors) are chosen for their quick response and reliable performance. Our standard thermocouple is a Type K. Type S thermocouples are available by request on Rampmaster equipped ovens at additional charge.
KH Features
