Overview
DOWTHERM™ 4000 inhibited ethylene glycol (EG) is a high-quality thermal fluid with the highest maximum use temperature of any glycol-based fluid. DOWTHERM™ 4000 is dyed a bright, fluorescent orange color to aid in leak detection in a variety of systems.
DOWTHERM™ 4000 is comprised of 92% EG and 8% corrosion inhibitors and water, allowing a greater thermal stability and higher operating temperature up to 350°F (175°C). DOWTHERM™ 4000 also provides burst and freeze protection down to -100°F (-73°C).
DOWTHERM™ 4000 provides exceptionally long fluid life in thermally demanding applications and reduces the frequency of maintenance intervals.
