With a recommended operating temperature up to 120C (250F), and freeze protection down to -51C (-60F), this inhibited ethylene glycol based fluid is the most widely used fluid for heating and air conditioning systems. A specially formulated inhibitor package provides excellent corrosion protection for common metals used in HVAC systems. The inhibitors are easily maintained, long-lasting, and replenishable, which means intervals between fluid changeouts are extended and long-term fluid expense is minimized. DOWTHERM SR-1 Fluid routinely lasts more than 20 years in properly maintained systems.
