I’m trying to compare the capacities of different heat transfer fluids to see if there is something that would be suitable to use for both low temp chilling and high temp heating. I don’t know if there is anything that would meet this need.
I would like to be able to go from -40c to 150c with a open bath system. This way I could use one chiller/heater for different purposes, running one fluid, instead of having to drain one out to put another in. Anyone find something that works for this?
Ethylene / propylene glycol + h2o
mixtures will work for low temp chillers, but not good for higher temps
-51C (-60F) to 110C (230F) in a open system
Pure Silicone Oil, 100 cst Super Lube
-50C to 200C
Would it still flow through chiller lines at a low temp?
70°C to 288°C in open system
@Breakingdabs recommends this for running a hot condenser
Sounds like it would be really thick when cooled.
20°C to 150°C in open system
Much cheaper ($250 for 5 gal) than Dynalene 600, doesn’t go as high but might be easier to drain out if I wanted to switch to a chiller fluid
