Does anyone still have a Thermasan unit or want one? I have a
complete Thermasan system out of a 1973 Superior that I will sell
reasonably for parts. I do not know if it works, but it is all there.
If no one is interested, I will sell the parts on eBay. I only
mentioned this to the list since when I googled it, there were a
number of GMCers who had written comments about it. It is a Thetford
manufactured system that used the exhaust system to incinerate waste
from the waste tanks.

Henry,
I would be interested if I can retrofit it to my 1973 Glacier.

Rob,
Wouldn't it be grandfathered?

If it is operating properly who would even know you had it? Or would they even recognize what it was if they saw it? As it is an exhaust modification it would not be allowed on a newer vehicle but it was a factory option on GMC's. Not sure of the years it was available from the factory.

Steve,
I reckon the operative word in your message below is "If."
I'm sure anybody would recognize what caused the strange odor / liquid
coming out of your exhaust "If."
Regards,
Rob M.

If operating properly there should be no liquid. The Thermasan has a speed sensor and a vacuum sensor. You have to be going over a specific speed (don't recall the speed at the moment) and have a vacuum reading that indicates the engine is working hard. Coast and/or slow down too much and the unit stops functioning until proper operating conditions are restored. Ya gotta have a hot exhaust and be moving. So the reported "diaper pain" odor should be the only indication it is functioning. Hopefully that will keep the tailgaters at bay. If that doesn't get them to back off then maybe some modification to the macerator system could be developed. <GRIN>

I have two people ahead of you, but they want a complete unit. I am going
to take it off and if it is operational as a complete unit, I will give
them first choice. I do not know how long it will take to take off and
test, but when I do, I will let you know, as that will determine the price.
I was told it was working, but that was years ago. Do you have one now?

Hello HenryÂ
Thanks for getting back so quickly. I do not have a unit, but would like to Detroit one.
Im looking forward to hear from you, even though the chances seem to be slim for me to get it.
Thanks Kurt

Henry et al...
One of the important parts is the fitting in your black tank. The pickup is just pushed into a rubber grommet, but the stanless screen and the plastic barb with the contacts for the level sensor are both specials and there are probably no replacements available. (after 25years - ya think?)
They were never, to my knowledge, declared to be illegal. We did a lot of testing and other than the stink, there was no emission issue. Even that stink when running at what we called the odor limit (judged by a consensus of the engineering staff), was barely measurable by GC. Our automotive emissions rack could not even find a change at the "knock the buzzards off the S-wagon" level. I had to be very aware of the wind direction when testing as we did like the neighbors.
The only legal problem was that many states at that time (early emissions laws) had a statute that prohibited modifying any vehicles exhaust system. This was interpreted (in PA at least) to include drilling the hole required for the exhaust probe. There was nothing that could be said if the unit was a factory install option.
So, if you install it, just say it is factory and let them try to find the build orders to prove you wrong.

The exhaust fitting on my Thermasan is pretty well corroded. As I am installing JimK's SS exhaust I'm planning on welding a SS exhaust O2 sensor bung on the pipe and plumbing the Thermasan "output" to that. (At the same time I'll weld on another bung for an O2 sensor if I should decide to go FI.)

Matt,
Did you work for Thetford or GMC? I plan to take great care taking off the
system. My parts man is getting the proceeds for the deal, so I am sure he
will probably wear white gloves. Thanks for the tip on the black water
tank fitting. I will give Marvin a camera to take some pictures while he
is disassembling the system. That in itself should be a hoot.
Did you have any experience with the Electra Magic recirculating toilet? I
like these since they use so much less water than regular toilets. I am
looking for the fill valve option to install on mine, but I am having
trouble finding one.
I will keep the group posted on my progress with the Thermasan.

Henry,
In 1973~4 I worked for Thetford in the Thermasan group in the Ann Arbor R&D labs. We were trying to develop and market a commercial unit for buses and such. I died because the authorities that corporate though we should go to for approval didn't want to approve it but could not come up with a reason, so they just waited us out until the first oil embargo shut things down.
Make sure that your guys gets all the parts. I had a box full of T'san parts that seems to have gone missing in the four moves since. I don't think a speed switch is even still available anywhere. That pill with wires out both ends near the tank is the level sensor. A good product but I think the company is gone.
As to a fill valve. It is nothing special, just plumb in something that is not easy to leave open.

Thanks for the quick reply. I still think the Electra Magic could be
a great solution for today's smaller RV's.
