Hi All, has any of you used Freez-Kontr'l Glycol in your Aqua-Hot broiler?

Description
–
The complete heat transfer fluid and antifreeze. Non-toxic, inhibited propylene glycol for chilled water, hydronic and other closed systems.

Description

Freez-Kontr’l is a formulation of propylene glycol, dipotassium phosphate corrosion inhibitor and de-ionized water. The fluid is colored blue to aid in leak detection. It has an operating temperature range from below -60°F to 230°F and solutions in water provide freeze protection to below -60°F and burst protection to below -100°F.

Freez-Kontr’l is nearly odorless and the product of choice when contact with potable water is possible. The ingredients used in its manufacture are GRAS (generally recognized as safe), under Title 21, Part 182 of the US Code of Federal Regulations, where accidental or incidental contact with potable water could occur.

Great question!
Here's what I found:

"It provides optimum
corrosion protection for most metals, including copper, steel,
brass, etc." It does say not to use it on galvanized surfaces.
