EUROTHERM 181 AND THERMINOL LT COMPARISON AS SYNTHETIC HEAT TRANSFER FLUIDS
Chemie Eurotherm 181
Product Description:
Chemie Eurotherm THT is a synthetic aromatic hydrocarbon-based two-phase heat transfer fluid for liquid and vapor applications, recommended for use in the temperature range of -80°C to 315°C. Normal boiling point 181°C, with excellent low-temperature viscosity, low-temperature flow, and heat transfer characteristics. Suitable for liquid phase heating systems operating between -80°C and 315°C, or for vapor phase heating systems operating between 181°C and 315°C.
Recommended Application Temperature:-80~315℃
Recommended application industries:
Chemical fiber spinning manufacturing (melt spinning spandex spinning box, imported dty texturing machine hot box); pharmaceuticals, fine chemicals, etc.
Packaging: 180KG/galvanized drum
Storage: Store in a cool, ventilated area away from sunlight and UV exposure.
