EGHTF - Ethylene Glycol Heat Transfer Fluid
EGHTF heat transfer fluid is an inhibited ethylene glycol designed for use in hydronic systems. The inhibitor system is designed to protect metals commonly found in residential and commercial installations such as brass, copper, solder, steel, and cast iron. The EGHTF formula also includes a fluorescent dye, for leak detection, and an anti-foam to minimize foaming during service. The effectiveness of EGHTF heat transfer fluid in preventing corrosion has been proven both in use and in extensive laboratory testing. Using EGHTF in place of brine solutions or uninhibited glycol/water solutions lowers maintenance costs and improves heat transfer efficiency.

Applications
Line Heaters
EGHTF heat transfer fluid is recommended for use in line heaters. A line heater circulates a heated fluid around a pipe to raise the temperature of the pipe contents in order to control reactions or ease pumping operations.
Snow-Melting and Refrigeration Systems
EGHTF heat transfer fluid is recommended for snow-melting systems for loading ramps, walkways, highways, and airfield runways, and as a coolant in ice rinks and air conditioning systems.
Combination Heating and Cooling Systems
EGHTF heat transfer fluid is recommended in combination heating and cooling systems for large buildings. The excellent corrosion protection afforded by EGHTF heat transfer fluid prolongs the life of the piping in these systems. EGHTF heat transfer fluid is also excellent for solar energy collection systems.
Thermal Energy Storage Systems
EGHTF heat transfer fluid is recommended for use in all thermal energy storage systems. The specially formulated inhibitor package is designed to protect common system metals from corrosion at glycol concentrations as low as 20%.
CAUTION
EGHTF heat transfer fluid must not be used where contact with food or potable water is possible. EGHTF heat transfer fluid is available for applications where contact with food or potable water is possible.
