JEFFCOOL® E100 Inhibited Glycol is an inhibited ethylene glycol used as an industrial coolant and heat transfer agent. The inhibitor system is designed to protect brass, copper, solder, steel, cast iron, aluminum, and other metals commonly found in industrial cooling and heating systems. A foam inhibitor is included to minimize foaming tendencies during service.

The effectiveness of JEFFCOOL® E100 Inhibited Glycol in preventing corrosion has been proven in extensive laboratory simulations and in actual service tests. Using JEFFCOOL® E100 Inhibited Ethylene Glycol(s) for heat transfer applications in place of brine solutions or uninhibited glycol-water solutions lowers maintenance costs and improves heat transfer.

CAUTION: JEFFCOOL® E100 Inhibited Ethylene Glycol(s) must not be used where contact with food or potable water is possible.



Line Heaters

JEFFCOOL® E100 Inhibited Ethylene Glycol is recommended as a heat transfer fluid for 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

JEFFCOOL® E100 Inhibited Ethylene Glycol is recommended as a heat transfer fluid for snow-melting systems for loading ramps, walkways, highways, and airfield runways, and as a coolant in ice rinks and air conditioning systems.

Thermal Energy Storage, Heating and Cooling Systems

JEFFCOOL® E100 Inhibited Glycol is recommended as a heat transfer fluid in combination heating and cooling systems for large buildings. The excellent corrosion protection afforded by JEFFCOOL® E100 Inhibited Glycol(s) prolongs the life of the piping in these systems. JEFFCOOL® E100 Inhibited Glycol is also an excellent heat transfer medium for solar energy collection systems.
