What is Inhibited Ethylene Glycol?
Inhibited ethylene glycol is a heavy-duty heating fluid formulated with advanced corrosion inhibitors to protect HVAC, industrial boilers, process cooling, and closed-loop thermal systems from freezing, corrosion, and scale buildup.
Unlike uninhibited glycol, which quickly degrades and turns acidic, an ethylene glycol inhibited formulation helps extend equipment life by protecting contaminant metals such as steel, copper, brass, and solder while maintaining high thermal performance. Compared to propylene glycol-based fluids, ethylene glycol offers superior heat transfer efficiency and lower viscosity at extreme temperatures, making it the industry standard for demanding industrial ethylene glycol heating systems across Canada.
Why Dynatherm for Inhibited Ethylene Glycol Applications?
Dynatherm is a premium inhibited ethylene glycol-based heat transfer fluid designed for long-term system protection in industrial, commercial, and oilfield applications. It can function effectively as a stationary industrial glycol radiator fluid where maximum thermal efficiency is required.
Dynatherm can either be supplied in concentrated form or as a completely formulated, pre-diluted solution with high-quality deionized water. At a standard 40% solution by volume, Dynatherm provides dependable freeze protection down to -25°C and boil protection up to 105°C without thermal degradation.

FAQ
Why use inhibited glycol instead of regular ethylene glycol?
Regular (uninhibited) ethylene glycol helps prevent freezing but lacks critical chemical protectants. Over time, it breaks down into acids that aggressively attack system metals. Dynatherm adds protective chemistry that neutralizes these acids, helping extend equipment life and maintain optimal system efficiency.
What is inhibited ethylene glycol used for?
Common applications include commercial HVAC chillers, industrial process loops, ethylene glycol heating systems, line heaters, and heavy-duty hydronic boiler operations.
Is inhibited ethylene glycol safe for hydronic heating systems?
Yes, it is widely used in closed-loop industrial and commercial hydronic systems. However, because ethylene glycol carries a higher toxicity profile than propylene glycol, it should only be used in systems where there is no risk of incidental contact with potable water or food processing lines.
How long does inhibited ethylene glycol last?
Service life depends heavily on operating temperatures and fluid maintenance. When properly monitored and maintained, an industrial heating fluid like Dynatherm can provide years of reliable, high-efficiency performance.
Can Dynatherm be used as a glycol radiator fluid?
While Dynatherm is an exceptional industrial heat transfer fluid and coolant for HVAC, line heaters, and boiler systems, it is designed primarily for stationary industrial and commercial applications rather than automotive radiators.
