HT Series

Larger Shop Design

Perform your heat treating in-house with our larger HT Series heat treat oven. The HT's are designed specifically for private work benches, commercial shops and industrial prototyping needs. They offer size, accuracy, and performance in a well conceived and executed design.

From tool makers to prototypes to color case hardening the HT Series represents the ultimate in shop sized heat treat ovens.

The HT's are available in a variety of control choice options as well as the solid state output option, which you want.

We offer 2 sizes. Please see the Specifications section below for details.

Features

Side Opening Doors

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 HT'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 Handles

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, one-handed in design and serves as the door latch as well.

Relay Access Port

All HT 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.

Door Shields

The HT'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.

Swing View Equipped

Our TAP II and Rampmaster temperature controls are fitted to 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 your shop. It's that simple.
 
The swing view pairs well with touchscreen controls like the TAP II as viewing angle can be perfectly aligned. You'll love it.

Firebrick Construction

Like all our heat treat ovens, HT models are built completely of firebrick.

Firebrick has the desired characteristic of storing heat and then releasing it slowly and gently during the soak/hold portion of the process. It's this particular quality that serves the heat treat process so well and that's why we use it.

Loud Alarm Output Jack

A Loud Alarm output jack is included to connect our optional Loud Alarm. Enjoy 80db of irritating alarm bliss and never miss another quench.

2000°F Maximum Temperature

The maximum usable temperature for the HT models is 2000°F (1093°C). This maximum is well within the range for the vast majority of steels used by knife makers, 3D printers and machine shops.

Maintenance Parts Tag

To assist you in replacing worn items we have included a maintenance parts tag indicating the proper Evenheat part numbers for anticipated maintenance items.

Wish we had this decades ago.

Strong Stand and Tool Rest

Stands are strong and include a tool rest. Cool!

Power Interrupt Switch Equipped

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!

Build Options

TAP II or Rampmaster Controls Option

HT models are available with your choice of the TAP II or Rampmaster temperature controllers.

 

Check out our Controls tab for detailed descriptions of both controls.

Quiet Drive Solid State Relay Option

All HT models are available with our Quiet Drive Solid State Relay option.

Our Quiet Drive Solid State Relay System offers tight temperature control, high reliability and increased heating element life. The Quiet Drive is arguably the best designed and best performing solid state system on the market.

Voltage Options

Our default production for HT Series models is 240V, Single Phase.

 

We do offer to build HT Series models​ in 200V, 208V, 220V and 230V by request.

All controls available on the HT Series models will operate properly on both 50Hz and 60Hz line frequencies. To say it another way, line frequency has no effect. It doesn't matter.

Evenheat recommends that you check your operating voltage before ordering or placing the oven in service.

Voltage Phase Options

HT Series models are produced in a single phase design only.

3 phase Delta and Wye (380V, 400V and 415V) designs are not available.

The loud alarm attaches and plugs easily into your TAP or Rampmaster equipped control panel and can easily be added at any time.
