electric tube furnaces

[Don Halter]

Anyone have a use for some large electric tube furnaces? These were pulled from a lab several years back and were in good working condition. They have been stored in a high humidity environment, though and would need thorough drying before beoing fired up. I think two are 1600*F and two 1000*F. There are no control units, just the tube sections with the electrical connectors. They are about 4 1/2' long. I can take some pics if anyone is interested. I hate to throw out $15,000 worth of furnaces!

P.S. Free if you come pick them up (Central TX).

Don,
Do those need three phase hook ups?
Could 220 single phase work?
You have my attention.

There is no control unit/power supply for them so they are basically just elements with the leads protruding through the shells. I'm guessing you could hook them up to just about anything as far as a power supply. I think one has the manufaturer info on the side. With that, I should be able to get the info from the company as far as power requirements.

These were given to me by a private researcher a couple years ago when he decommissioned his lab. I've never set them up and I'n not much of an electrician! they'vce been sitting at a brother-in-law's house since then.

Don, I'd love one of the 1600 F ones if you'd be willing to ship it! May be too much trouble, but if not, let me know what the cost is and I can get some money to you for shipping...

Geno, I used to use these for pulsed laser deposition of thin films and C60 back in my physics research days....you can hook them up to a controller (PID) and have the output modulate a solid state relay to control the elements. They usually require 220 V for the elements.

It was a physics lab they came out of. the lower temp ones were being used for annealing semiconductor doohickies (technical term ). The larger one were being used for thin film deposition of some sort. They were replaced with a different shape/size furnace since the assemblies wouldn't fit. I was told they were used about two weeks then removed and stuck in a trailer with a tarp over it.

I'll get some pics and info of them for y'all. I thought they might could be used with large salt pots or for treating sword blades. Mabye cooking rattlesnakes as well.

I am curious also. If you can post a picture, it would help.

Preeesheate it.

I want dibs on the other 1600 F job.
How big around are they?
Aren't you near College Station somewhere?
I'll bring you something when I come.
Don't know when, but I'll get it up on my calendar somewhere soon and let you know.
Thanks Man, I got some ideas.
Do you need anything in particular for your shop?

Could thy be built into a tempering oven, 300Deg to 600Deg,
how about a unit to do both high temp 1600 deg and tempering.
Defiantly interested. How many do you have, Gib

OK...it's been a while, but I finally got them moved and such. There are only two that are still in serviceable condition(the shorter but larger diameter ones). The other two are pretty trashed. I took a bunch of pictures this weekend and will post them up on a site. At one time, I had manufacturer's info on them, but not any more. I *think* the larger diameter ones were the higher temp ones. There are a couple serial numbers which will be in the pics. I'll set up the webpage with the info tomorrow so y'all can look at it. I figure that will be much easier than trying to email a couple megs worth of pics!
