Ethylene Glycol-Based Industrial Heat Transfer Fluid

Pre-Mixed and Concentrate Available

EGI-HTF is an industrial formulated heat transfer fluid containing an inhibitor package that controls corrosion of metals, helps prevent scaling and fouling of heat transfer surfaces and buffers the pH to maintain it in the optimum operating range. EGI-HTF tested according to the ASTM standard methods, exceeds the performance requirements of the industry. The product is available as concentrate and ready-to-use premixes. The inhibitor system is based on a high-phosphate, multi-component formulation which makes it ideal for a wide variety of commercial and industrial applications. 

Operating Temperature Range and Freeze/Burst Protection 

EGI-HTF has a recommended operating temperature range of -60ºF to +300ºF and can be used to provide both freeze and burst protection for systems which may be exposed to very low temperatures. To obtain adequate freeze protection, select a glycol concentration with a freeze point at least 5°F below the lowest anticipated ambient temperature. When diluting concentrate maintain at least 30% EGI by volume for adequate corrosion protection. 

Corrosion Protection

EGI-HTF provides outstanding corrosion protection for copper, brass, solder, steel, and cast iron and aluminum. It meets or exceeds the standard industry corrosion test for these metals. It is also compatible with most plastics, elastomers and types of rubber. The Inhibitor package protects iron, steel and aluminum metal surfaces from acidic attack and rust formation. EGI-HTF also contains Tolyltriazole to protect copper, brass and solder used in multi-metal systems. The buffering system neutralizes acids formed by the normal thermal and oxidative degradation of ethylene glycol, thus maintaining the pH in its optimal range.
