DOWTHERM 4000 inhibited ethylene glycol (EG) is comprised of about 92% EG and 8% corrosion inhibitors and has a bright fluorescent orange color. The lower EG content allows for a higher concentration of corrosion inhibitors which in turn means DOWTHERM 4000 is capable of operating at higher temperatures than DOWTHERM SR1 i.e. from -60 °F to 350 °F. This makes DOWTHERM 4000 a higher end, niche type product which is also capable of providing 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: Laser cooling, jacketed vessels, general industrial heating, boiler, reactor vessel, and waste heat recovery.
Feature: Odorless and moderate in acute oral toxicity Benefit: Perfect for a general industrial application where there is no chance of being consumed
Feature: Excellent freeze and corrosion protection without significant reduction in heat transfer performance
Benefit: Single fluid solutions that save money by reducing variations in pump design, heat exchanger cost, and a lower total cost of ownership
Feature: Contain specially formulated industrial inhibitor packages that are effective in preventing corrosion of metals commonly used in HVAC and process heat transfer equipment Benefit: Extend fluid life, system life, and lower maintenance costs
