Propylene Glycol Ppg

Tono Frost 593 is NSF certified with HT1 (Heat transfer fluid with incidental contact)

Inhibited PG is used as an industrial coolant, antifreeze heat transfer agent. The inhibitor package has been designed specifically to protect brass, solder, copper, steel, aluminum, cast iron, and other metals commonly found in the industrial cooling and heating systems.

The effectiveness of Inhibited PG in preventing corrosion has been proven in extensive laboratory and in actual service tests. Using the product for heat transfer applications instead of brine solutions or uninhibited propylene glycol helps in reducing maintenance costs and improving heat transfer efficiency.
