Unless you're making juice-flavored popsicles in your refrigerator, you generally don't want liquids to freeze. Ice, after all, is best reserved for our drinking glasses not in fuel tanks, filters and fuel lines.
Luckily we're serving you a chemical cocktail that can avoid the ice. Diethylene Glycol Monomethyl Ether; methyl carbitol. Or, let's just call it by its common name: Prist® HI-FLASH® HI-FLO™ Anti-Icing Aviation Fuel Additive. This item, known as a fuel system icing inhibitor (FSII), works by reducing the occurrence of suspended ice crystals. As you know, this may compromise the flow and efficiency of said system and for an operating engine, that's not good.
Prist® HI-FLASH® HI-FLO™ Anti-Icing Aviation Fuel Additive is specifically designed to separate from your fuel and attack dissolved water, lowering its freezing point and making your entire operation safer when things get frosty. Other benefits abound. It's safer than conventional anti-icing additives because it's less toxic, less volatile and easier to use .
This FSII is so effective it is authorized by the United States Armed forces under Military Specification MIL-DTL-85470(B) as well as under the American Society for Testing and Materials' Standard D4171 for use in civilian jet fuels. And because it conforms to rigid standards, frigid conditions are no match for Prist® HI-FLASH® HI-FLO™.
NOTE: This item is recommended for every refueling at a dosage rate of .10% minimum to .15% maximum by volume. Hi-Flo delivers the product at a rate compatible with a 40 to 55 gal. per minute fuel nozzle rate.
