DOWTHERM SR-1 inhibited ethylene glycol offers effective heat transfer over a wide temperature range: from -60 °F to 250 °F and provides freeze protection down to -60 °F.
DOWTHERM SR-1 inhibited ethylene glycol (EG) is comprised of about 95% EG and 5% corrosion inhibitors. DOWTHERM SR1 has a bright fluorescent pink color and is the most popular EG based product within the Dow portfolio. In fact DOWTHERM SR-1 is the most widely recognized brand name in the industry. It offers effective heat transfer over a wide temperature range: from -60 °F to 250 °F and provides freeze protection down to -60 °F.
Dowtherm Glycol thermal fluid products are used to transfer heat effectively and affordably. Dowtherm Glycol thermal fluids are a cheap, but toxic if orally consumed, means of providing freeze protection while still allowing for relatively high heat transfer efficiency.

The product line applications may include: Hot water heating (radiant floor heating), Ground Source Heat Pumps (GSHP), Snow melt systems, Chill water (HVAC), Boiler Jackets, Laser Coolants, Thermal Energy Storage (TES), Ice skating rinks
Feature: Odorless as well as moderate in acute oral toxicity
Benefit: Where there is no chance of being consumed, this grade is a workhorse
Feature: Excellent freeze and corrosion protection without significant reduction in heat transfer performance
Benefit: Single liquid phase solutions that save capital by reducing variations in pump size, heat exchanger design, and an overall lower total cost of ownership
Feature: Contains a specially formulated industrial inhibitor package that is effective in preventing the corrosion of metals that may commonly be used in HVAC and process heat transfer equipment
Benefit: This extends fluid life, system lifespan, and lower maintenance costs overall
