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.
