As Evenheat says: Better by Design!

7"x7"x7" Chamber

The chamber of the Cube 7 measures 7" x 7" x 7". Perfect for machinist, prototype work and smaller blades.

Side Opening Door

Heat treating involves removing extremely hot materials from the chamber for quenching, and safety is paramount. In the Cube 7, the door swings out and to the side, positioning the super-heated surface safely away from you. This thoughtful design lets you focus entirely on your work without the risk of accidental contact with the hot door.

Full Firebrick Construction

The Cube 7, like all of Evenheat's heat treat ovens, is constructed entirely from premium firebrick.

Firebrick is renowned for its ability to absorb and retain heat, then release it gradually and consistently during the critical soak/hold phase. This unique characteristic ensures exceptional temperature stability, making it an ideal choice for precision heat treatment.

Cool Touch Handle

The handle and latch on the swing-out door are thoughtfully positioned at the front for easy access—no more fumbling along the side. This spring-loaded phenolic handle stays cool to the touch, is designed for effortless one-handed operation, and doubles as the secure door latch, ensuring both convenience and safety.

Relay Access Port

The Cube 7 features a convenient Relay Access Port, making relay replacement quick and hassle-free.

With the easy-to-remove access plate, you can reach the relay without disassembling the control panel or navigating complex internal wiring. All you need is a screwdriver!

Since mechanical relays naturally wear out over time, this innovative design ensures you can perform replacements with minimal effort when the need arises. Simple, effective, and built for practicality.

Door Shield

The door shield is designed to protect the firebrick from damage while also minimizing heat exposure to the door and handle, ensuring durability and safer handling.

Swing View Equipped

The TAP II and RampMaster temperature controls are housed in an innovative Swing View Adjustable Enclosure.

This pivoting, swing-up design lets you rotate the control panel to your ideal viewing and programming angle. When finished, simply lay it flat for easy visibility from across your shop—it's effortless and convenient.

The Swing View enclosure is especially compatible with touchscreen controls like the TAP II, allowing you to perfectly align the viewing angle for maximum comfort and usability. You’ll appreciate the difference!

Maintenance Parts Tag

To assist you in replacing worn items, Evenheat has included a maintenance parts tag on the Cube 7 indicating the proper Evenheat part numbers for anticipated maintenance items. Brilliant.

Controllers

The Cube 7 is available with your choice of the Icon, RampMaster 3, or TAP II temperature controllers.

The Icon, born from the innovative Bartlett Spark platform, disrupts the industry by delivering advanced touchscreen technology at an affordable price point. It's the controller that comes as standard with the Cube 7.

In the latter part of 2023, the Icon, built upon Bartlett Industry's new Spark platform, underwent extensive field testing by Bartlett, Evenheat, and industry experts. The results were impressive: programming was found to be intuitive, touchscreen interactions received top marks, and, as expected, the Quiet Drive Solid State relay performed flawlessly, concluding the tests successfully.

In line with Evenheat's commitment to enhancing control designs, the Icon improves upon the Spark platform by introducing features like Special Limits thermocouples for unmatched temperature accuracy and non-metallic faceplates to boost Wi-Fi connectivity for the Bartlett online app. The Icon sets a new benchmark in the industry, delivering exceptional performance and value.

The TAP II Controller shines as the premier selection in Evenheat's lineup of temperature controllers, featuring an expansive screen and an intuitive layout. The process of setting and executing firing schedules is remarkably fluid and straightforward. The advanced engineering within the TAP II ensures consistent, accurate results, especially when integrated with the Quiet Drive Solid State Relay system.

The TAP II is fitted with Special Limits thermocouples, assuring extremely precise temperature readings. Its non-metallic faceplates also contribute to superior Wi-Fi reception, offering smooth and uninterrupted connectivity with the SDS online app.

Choose the TAP II for a seamless, efficient control experience. Connect with the app and set off on a journey of streamlined and precise temperature management.

The RampMaster 3, developed from Bartlett Instruments' V6-CF platform, is meticulously designed for glasswork but is also highly effective in heat treating applications. It is an excellent option for those who prefer a classic interface, featuring user-friendly buttons and a clear display for easy operation.

Upholding the high standards of Evenheat, the RampMaster 3 is equipped with a Special Limits thermocouple for accurate temperature readings. In combination with the Quiet Drive Solid State relay system, the RampMaster 3 delivers outstanding performance while retaining a straightforward, traditional interface. This controller is an ideal match for craftsmen and artisans who value a mix of classic ease-of-use and modern technology.

Quiet Drive Solid State Relay

Bid adieu to the frequent troubles and costly repairs associated with mechanical relays.

Welcome the groundbreaking Quiet Drive Solid State Relay System by Evenheat, an epitome of innovation with its absence of moving parts, guaranteeing an enduring, maintenance-free lifespan. Enjoy the system's exceptional performance, providing precise and controlled heating that consistently delivers top-notch results.

Relays Demystified: Solid state relays (SSRs) stand as a sturdy and reliable substitute for traditional mechanical relays, which operate with movable metal contacts and a magnet coil activated by electricity. SSRs leverage a compact semiconductor block devoid of any moving components, eradicating physical deterioration and significantly enhancing kiln temperature control.

Advantage 1 - Perpetual Operation: The lasting nature of SSRs is undisputed. Free from the physical decay of moving components and electrical sparking, they surpass the lifespan of conventional relays significantly. The repetitive clicking from a kiln, indicative of mechanical relays at work, eventually leads to wear and the necessity for costly repairs. Conversely, Evenheat's SSRs deliver a silent and steadfast operation that endures in tandem with your kiln or oven.

Advantage 2 - Unmatched Temperature Precision: Mechanical relays have a limited cycling frequency to strike a balance between control efficacy and relay lifespan, typically one cycle every 10 to 14 seconds. SSRs, however, function at an astounding rate of 120 cycles per second, facilitating quicker adjustments and unparalleled temperature accuracy. All Evenheat controls, including the now standard Icon that replaces the previous basic Set-Pro controller, exploit the rapid cycling of SSRs to achieve unmatched temperature precision.

Advantage 3 - Prolonged Heating Element Life: Solid state relays utilize Zero Crossing technology, activating and deactivating precisely at the 0V juncture of AC power variations. This feature considerably extends the longevity of heating elements by ensuring they function at optimal voltage, thereby minimizing wear in comparison to mechanical relays without this technology.

Excellence by Design - 30 Amp Rating: Evenheat meticulously selects SSRs with a 30-amp rating but operates them at only 15 amps, offering a generous margin for consistent, dependable performance. This method ensures the SSRs operate well within their derating curve even at a 15 amp load, promoting cool operation and durability, a testament to Evenheat's commitment to excellence.

Excellence by Design - Externally Mounted SSR Heatsinks: Adequate cooling is essential for the longevity of SSRs. Evenheat achieves this by externally mounting the SSR heatsinks, enhancing air circulation and preventing heat build-up within the control enclosure. This arrangement avoids heat transfer between the control enclosure and SSR, aided by standoffs that create an air gap for cooling. This careful design ensures optimal performance of the SSRs, supported by an impressive six-year track record of zero failures.

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!
