Always ramp up heat slowly. If you heat your oil too much it can crystalize in the hose and or catch fire
This cleaning was from ~ 2 months of daily ramp up to 240C using Duratherm S. We actually had a Duratherm rep get us to buy the “G” once and it was way worse. G cracked right away and smoked like a tweeking hoe. That cleaning wasn’t fun. We still have around 2 gallons of G left.
Also wooks will try and mix the S and G together and destroy a grand in thermofluid (50L roto) real quick. “but the bottle looked the same” smfh.

Ive had the same 5 gallons of duratherm s in the roto for a long time now a no corrosion. Bought 20 gallons 7 yrs ago and am still using it, it was dirt cheap then before they knew people in cannabis were using it

We run up to 240C all shift long. I’m also not at liberty to say why we do this. We’ve run this way for the last 3 years though.

We import Jarytherm DBT in drums. Pour down into 5 gallon pails too. It’s good to 350C, but that’s probably overkill for extraction

What’s it made out of? Silicone?
I’m an overkill kind of guy. I like the look of those fluids. Thanks for the tip!
DBT stands for dibenzyltoluene.
Sounds like an awful, angry molecule, but ships as non-hazardous material. We repackage in house
We’ve used DOW XIAMETER PMX-200, 50cst Silicone Fluid on our YH Chem wiped film units for years. Works great. If you have a glass unit it’s really great because it doesn’t get dark when heated and block your process view. It’s back ordered like crazy right now, but I ordered a couple barrels when I found out there was a shortage. They should arrive next week and I’ll have it in stock.
Did you get any yellowing/darkening with the Caldera 7?
I’m torn between 5gal of Duratherm S or Caldera 7.
I’m looking to run the fluid in an open bath at temps of -40C to ~120C, I wont be running at 120C too often. I’d like to be able to see whats going on in the reactors without the yellow if possible, do both fluids come water clear at the start?
I have duratherm that was only used in open bath decarbing in a roto and its about 7yrs old and no discoloration
