Product Overview
DOWFROST™ HD 50% 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 50% is comprised of <50% water, 48.0% to 54.0% propylene glycol, and <5% corrosion inhibitors & proprietary additives.
DOWFROST™ HD 50% 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 50% is particularly well suited for applications exposed to temperatures between -28°F and 325°F (-33°C and 162°C).
