Chemicals for ThermaSan
Interesting that you found some of the original advertising info. I remember as a kid that the ThermaSan was HIGH on the list of RV owners wants, but it's cost was the main deterrent to installation. I found the same flyer that you have and an additional one in the owner documentation from the units I purchased on eBay.
Yes, Thetford did recommend that you use Aqua-Air with the ThermaSan, but I suspect Thetford was looking for a continuing revenue stream (it is razor blades that make money, not the razors). While we have had a few good laughs about "don't follow us, we are burning "s&*t", the system does a complete job of destroying odors. There have been a few occasions while the ThermaSan was running that we stopped momentarily to check things and never once have we detected any odors or discharge. The system shuts down when the engine load drops or the speed falls below 35-40MPH. This ensures that there is adequate heat and gas flow to do the job before injecting effluence into the exhaust system. As for the Odor-Con (Chlorine Dioxide) being burned in the process, I am not all that worried as I only use an 1/2 oz per holding tank, and even if you break that down, you are only releasing oxygen and a small amount of chlorine (far less than evaporates off the top of a swimming pool).
BTW, understand that the fine mesh stainless screen in the intake probe on the black tank prevents solid matter from entering the system (only liquid and very small matter), so you still have to empty the tank the old fashioned way periodically (in our use, the ThermaSan is only used occasionally when dumping facilities are not available). We also have the A/S factory blacktank flush which I use to totally flush all matter out of the tank each time I empty the tank.
I have to admit, I installed the ThermaSan more from a nostalgic perspective and the novelty, but it does work and work well.
