    ethanol



    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.

    Re: ethanol

    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!
