ethanol

[mark957]

hello all.
I need to build a chiler that cooled to -30 ° C and heated to 60 ° C methanol.
my question is whether there are contraindications for the treated product.
if anyone has had experience with flammable methanol and what pressure it is recommended to keep the circuit closed.

Looking ath the methanol saturation table it remains under atmospheric pressure all the way from -30°C to +60°C, so using it as refrigerant is out of the question and a secondary system would need to be explosion proof.

Im glad I have no experience with it and wouldn't even get willingly near the stuff! :o
