Freezing Point of Propylene Glycol based Water Solutions

Pure water freezes at 32° F, but a 60% solution of DOWFROST propylene glycol pushes the freezing point down to -60° F. While the freezing point of pure glycol is only -39° F, the synergy between glycol and water results in a much lower freezing point. This is very important for closed-loop systems that may be exposed to freezing conditions.

Freezing point of Polyethylene glycol? | Yahoo Answers

Too much glycol will leave you with a freezing point far below what’s necessary while wasting funds on refrigerant. Too little, and you risk the entire system freezing, leaving the fermentation process to proceed unchecked! Remember that the freezing point in your system will rest around 10 to 15° F below your mixed glycol solution. Therefore, if your chiller is set to 27° F, you should ...

What happens when a glycol solution freezes?

In between, freezing points are non-linear. For instance, a solution of 10% ethylene glycol freezes at -3.4 C (25.9 F), 30% ethylene glycol freezes at -13.7 C (7.3 F) and 60% ethylene glycol freezes at -52.8 C (-63 F). The freezing point of a 60/40 ethylene glycol/water mixture is much lower than that of either pure ethylene glycol or pure water. Mixtures of propylene glycol with water follow ...
