DOWFROST™ HD 30%

30% Concentrate in Water, Yellow dyed, Industrial-Grade Inhibited Propylene Glycol (PG) Thermal Fluid for Heat Transfer Applications between 10°F and 325°F.
Product Overview

DOWFROST™ HD 30% inhibited propylene glycol (PG) is a prediluted, ready-to-use thermal fluid for easy fill & operation in a range of heat transfer equipment. DOWFROST™ HD 30% is comprised of <65% water, 27.0% to 33.0% propylene glycol, and <5% corrosion inhibitors

DOWFROST™ HD 30% is dyed fluorescent yellow for easy identification for industrial applications and is engineered to exhibit greater stability at higher temperatures than regular DOWFROST™. DOWFROST™ HD 30% is particularly well suited for applications exposed to temperatures between 10°F and 325°F (-12°C and 162°C).
