Therminol LT is a synthetic aromatic heat transfer fluid. It can be used in both the liquid and vapor phase between -75° C and 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 -75° 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 -75° C.
- Vapor Phase Operation - Therminol LT can be used in the liquid phase between
-75° C and 315° C. With a boiling point of 181° C at ambient pressure,
Therminol LT can be used in the vapor phase above 181° C.
Therminol
LT is used in a wide variety of industries, such as:
- Pharmaceuticals
- Specialty Chemicals
- Environmental Test Chambers
