SYNTHETIC HEAT TRANSFER OIL
Hy-Therm 707 is a synthetic heat transfer oil 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% higher than many widely used heat transfer fluids. This means that heat energy is absorbed and released by Hy-Therm much more quickly than typical mineral heat transfer fluids. Hy- Therm 707 also has a significantly higher heat capacitance than typical mineral heat transfer fluids. In open systems, Hy-Therm can safely be used at operating temperatures up to 400°F. Closed systems with inert gas (e.g. nitrogen) blanketing can safely operate with Hy-Therm 707 up to 700°F. Hy-Therm 707 is an undyed product.
