Heat transfer fluid vs hydraulic oil

May 14, 2008 7 Replies

I have an appliance which heats stuff in pots by basically having them sat in heated fluid, heat transfer fluid. Would there be a problem with using a thin oil instead such as hydraulic oil?



The pot is heated to just under 100C by means of an element, the only problem I can imagine is fumes, would heated hydraulic oil give off any?



Cheers.


Dunno about hydraulic - but brake fluid is good for a couple of hundred...

DOT3 is hygroscopic and strips paint, so, I'd avoid that. Any light oil would work - at least I've never heard of one that can't withstand

100C. Mineral oils will be long term stable, veg oils would gum up in time. If its under a litre or 2, baby oil is probably as cheap as it gets. Its light mineral oil with a wee bit of perfume, which I assume would quickly evaporate.

Silicone Dot 5 (NOT 5.1) is one of the cheapest and most convenient sources for silicone oils.

Right then, it smells a bit more than I expected.

Is it possible to add something to warmed oil to make it more fragrant?

I always preferred a woman. Enjoy :-)
