really cold conditions
I have a situation where is -50C on the fridge side and I need to transfer the heat/cool to a fan coil but I cannot use glycol as it turns to jello. What is used at these temps for a heat transfer fluid?

Hi Mike.
I believe a product called temper goes down to -55' C and stays fluid.

Re: really cold conditions
Would Dowtherm or siltherm work at -50?
Mostly found in the southern part of this green and pleasant land.

Hi Mike
if a small system volume, consider pure alcohol. The non drinkable stuff, highly volatile though.

Re: really cold conditions
Kerosene ( with out any wax ) is a good for this kind of jobs.
it is more safe than alcohol.

Re: really cold conditions
Delimone. Its somewhat corrosive and it likes mineral oil; not flammable and very low viscosity even at these temps.
