Quiet Drive Solid State Relay
Evenheat's patented Quiet Drive Solid State Relay is hands down the best investment you can make in your kiln!
With no moving parts, this relay is able to be triggered up to 60 times a second as opposed to the upper limit of 10 times a second on the default mechanical relay. This means incredibly tight temperature control ensuring each and every one of your firings is as accurate as possible.
The Quiet Drive uses a special method call "Zero Crossing" that will ensure that the heating elements are off when the voltage is at 0V - Giving your heating elements a break so that they will last longer, and you'll save energy!
The best part though? Since there are no moving parts - the Quiet Drive Solid State relay should never need replacing! You will save money and time by never needing to worry about this in the future!
Controller Selection
Evenheat has close relationships with the manufacturers of a variety of digital controllers. This means you will have nothing but the best the best in terms of performance and accuracy in your firings.
With a selection of multiple controllers available - you can choose exactly what fits your needs.

The top of the line. The bread and butter. The cream of the crop. The controller for those
who want to make their lives easier, improve their craft, and make incredible quality products.
This is
our top selling controller - And for good reason!
The TAP Smart Controller is without a doubt the best choice on the market
right now - It's easy to use, has stellar performance, and is packed full with features!
It has more
memory than any other controller, allowing you to more easily utilize, revise, and save many different kinds of
firing programs.
Storage for firing programs is virtually unlimited! Create as many profiles, with as many
steps as you'd like - you won't be limited by this controller.
Our favorite part though: When ordered with the
Wi-Fi Dongle, you can control everything from any device! Prefer to work on your computer or tablet - how about your
phone?
With an internet connection to your TAP Smart Controller, updates from SDS Industries can be applied to your controller automatically - ensuring you always have the most up-to-date software for years to come!

The TAP Smart Controller supports the Loud Alarm option.
Rampmaster
The Rampmaster provides additional versatility over the Set-Pro controller.
With
a numerical keypad, it allows the operators to create up to 12 firing
programs, each including up to 8 segments.
Need to make adjustments as you go? On-the-fly
adjustments and other menu functions are available to provide additional control and create your ideal firing
profile.
The Rampmaster also supports the Loud Alarm option.
Set-Pro

The Set-Pro is our basic, no frills controller. It gets the job done, but does not offer nearly as much flexibility as the others.
It offers the option to create 8 firing programs, with 8 segments each.
This is a good choice if you're only planning to occasionally use your oven and do not want room to expand in the future.
Loud Alarm Option
Don't worry about missing when your firing or treatment is complete - With the loud alarm option you'll slice through any loud shop to the tune of 80 decibels!
The Loud Alarm Option will notify you when your ideal temperature and hold has been reached, and more importantly - when it's over!
The TAP Smart and Rampmaster III controllers support a built-in jack for an easy install; simply plug it in!
MK Blade Fixture
A necessity for all knife makers! The MK 1 and MK 2 Blade Fixtures are used to hold your knives in place during heat treating.
The MK 1 will hold 4 blades, and while it is designed for the Evenheat KH series, it will fit in the KO, KF, and LB series as well.
The MK 2 will hold 6 blades and is designed for the Evenheat KO, KF, and LB series. It will not fit the KH models.
Power Interrupt Switch
The power interrupt switch is a useful safety feature which removes power from the heating elements of your kiln once it is opened, and reapplies the power once the lid has been closed.
If you believe you'd ever like to be open the kiln during firing, the power interrupt switch is a highly recommended addition to your new purchase.
