Hy-Therm™ 707 is a synthetic, heat transfer fluid that is more efficient than mineral oil based fluids. Its thermal conductivity (0.121 BTU / hr ft °F at 400 °F) is 50 to 100 percent greater than many widely used heat transfer fluids. This means that heat goes in and comes out of Hy-Therm™ 707 much more quickly. A pound of Hy-Therm™ 707 can hold 30+ percent more heat with a specific heat of 0.665 BTU / lb °F at 400 °F.
Hy-Therm™ 707 can safely be used in open systems up to 400 °F and in closed systems under inert gas at 700 °F. Fluid life and system cleanliness can greatly be enhanced when Hy-Therm™ 707 is used with inert gas (nitrogen, etc.) blanketing. Its low temperature fluidity eliminates the need to drain fluid during cold weather shutdowns, a common problem with many heat transfer fluids.

Systems using Hy-Therm™ 707 are both safer and cleaner. Hy-Therm™ 707 has a higher flash as up to 25 percent more heat is removed than comparable petroleum heat transfer oils. Systems remain cleaner because Hy-Therm™ 707 minimizes carbon deposits, which ensures superior heat transfer efficiency.
