WTS Heat treat Oven

[Sea Sick Steve]

Thermolyne FA1740-1 Heat treat oven 240v 1phase Has the control for temperature. Physical condition is pretty nice however 2 of the heating elements are bad and need replaced I found them but the cost is prohibitive for me to repair the unit. I considered just making some coils or purchasing some coils and retrofitting but I don't have the time of energy for another project at this time so time to part ways. I am located near Cleveland, Ohio I would like $275 for this picked up, I can load it. I can ship it as well, you pay all shipping costs. FYI the direct replacement elements I found are about $550 each. Wound coil elements of the approximate wattage are about 50 dollars each but the firebrick will need modified to accept this style of element.

Back up
Lower price $225

Could it maintain 400F on the remaining element(s)? I wouldn't mind having a dedicated tempering furnace.

Yes I believe that it would I will send a PM

Hope you don't mind- where did you find the heating elements for this? What was the cost? Can you share?

You can make your own by winding coils of the resistance wire then stretching them to whatever length needed. It's easy to bend/coil. Kanthal is the high temp stuff. There are calculators online to determine the best wire gage and length for your elements based on wattage.

True this is correct but the heating coils on this furnace are inside the brick they are covered and non accessible. I found a company that can provide a wound coil of the proper size at a reasonable cost but the insulating brick to hold the coils would need to be retrofitted This is just more work than I want to do. If somebody has the initiative for the project this is a good solid unit

Yup, on some you need to dig out the old elements. I have a couple Temco furnaces that have the elements cemented in also. Hoping I don't have to replace them any time soon. That stuff is pretty damned hard to grind out. I've done a few crack repairs on mine and it chewed up a few diamond burrs. Although they were cheap import and probably too fine a grit.

Steve- thank you for your reply,

BTT I still have this It could be retrofit the inside of oven and cabinet are in nice shape 150 bucks where it sits I can load

Just to add to my earlier comment - and maybe help Steve out a little, the newest style fire bricks can be cut with a hacksaw, they're very soft and still outstanding insulators. So this would not really be that difficult to retro. After thinking on it, I will probably go that route on mine if they ever need element replacement too.

Thanks for the comment This was my thought I just dont need another project and I do need the space back

If you do go with soft insulating fire brick, keep hard brick or a kiln shelf or a hearth plate on the bottom. I learned the hard way that pushing and pulling parts into the oven quickly wears ruts in soft fire brick.

The oven has been relocated Thanks for looking
