Generally, for anextended margin of protection, you should select a temperature in this table that is at least 3 C (5 F)lower than the expected lowest ambient temperature. Inhibitor levels should be adjusted for solutionsof less than 20% glycol .

2 The fluid isdyed bright yellow to aid in leak in water provide freeze protectionto below -50 C (-60 F) and burst protectionto below -73 C (-100 F).Recommended use temperature range: -45 C (-50 F) to 160 C (325 F)Suitable applications: single fluid processheating and cooling, closed-loop, water-based HVAC applications where propyleneglycol solutions are preferred or health and safety information for thisproduct, contact your Dow sales represen-tative or call the number for your area onthe second page of this sheet for a MaterialSafety Data Sheet (MSDS).*Trademark of The Dow Chemical ( ) (212) ( ) (212) ( ) (212) ( ) (212) ( ) (213) ( ) (214) ( ) (216) ( ) (217) ( ) (219) ( ) (220) ( ) (222) ( ) (223) ( ) (225) (227) (230) (237) (245) (257) (270) (310) Typical properties, not to be construed as specifications. Degree Brix is a measure of the sugar concentration in a fluid and is important in fermentation and syrups applications. Although there is no sugar presentin Dowfrost heat transfer fluids, the glycol affects the refractive index of the fluid in a similar glycol concentrations greater than 94% are not attainable with Dowfrost HD points are below -50 C (-60 F).
