Therminol LT

Back

herminol LT is a synthetic aromatic heat transfer fluid. It can be used in both the liquid and vapor phase between -100� F and 600� F (-70� C - 315� C). Performance features of Therminol LT include:

Low Viscosity - Low viscosity at exceptionally low temperatures make Therminol LT ideal for extreme cooling applications. Therminol LT is pumpable to -100� F (-70� C).
Excellent Low Temperature Performance - Therminol LT has the best low temperature heat transfer coefficient of all coolant fluids. Therminol LT has excellent heat transfer properties to -100� F (-70� C).
Vapor Phase Operation - Therminol LT can be used in the liquid phase between -100� F and 600� F. With a boiling point of 358� F (181� C) at ambient pressure, Therminol LT can be used in the vapor phase above 358� F (181� C).

Therminol LT is used in a wide variety of industries, such as:

Pharmaceuticals
Specialty Chemicals
Environmental Test Chambers
