Product Information DOWFROST - Anco Chemicals

1 DOWFROST * heat transfer fluidcontains specially formulated packagesof industrial inhibitors that help preventcorrosion. Because propylene glycolfluids have low acute oral toxicity, DOWFROST propylene glycol-basedfluids are often used in applicationswhere contact with food or beverageproducts could use temperaturerange: -45 C (-50 F) to 120 C (250 F)Suitable applications: secondarycooling and heating, freeze and burstprotection of pipes, various deicing,defrosting, and health and safety Information for thisproduct, contact your Dow sales repre-sentative or call the number for yourarea on the second page of this sheetfor a Material Safety Data Sheet(MSDS).*Trademark of The Dow Chemical CompanyProduct InformationDOWFROSTI nhibited Propylene Glycol-based Heat Transfer FluidTypical Concentrations of DOWFROST Fluid Required toProvide Freeze and Burst Protection at Various TemperaturesPercent DOWFROST FluidConcentration RequiredTemperatureFor Freeze ProtectionFor Burst Protection C(F )Volume %Volume %-7(20)1812-12(10)2920-18(0)3624-23(-10) 4228-29(-20)4630-34(-30)5033-40(-40)5435 -46(-50)5735-51(-60)6035 NOTE: These figures are examples only and may not be appropriate to your situation.

2 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 solutions ofless than 30% glycol.
