JARYTHERM® DBT
Product Description
JARYTHERM® DBT is a synthetic heat transfer fluid, formulated from a blend of dibenzyltoluene isomers. This fluid is engineered to provide exceptional thermal stability and efficiency in high-temperature applications, particularly in the chemical and plastics transformation industries.
Applications
JARYTHERM® DBT is ideal for heat transfer installations operating from 0°C to +350°C in the bulk (up to 370°C in the film) without air contact. It is commonly used in the chemical and plastics industries, including barrel extruders.
Specifications
JARYTHERM® DBT conforms to ISO 6743/12 class L-QD-350 and passes thermal stability tests such as ASTM D6743, DIN 51528, and GB/T 23800-2009 (1000h, 350°C).
Advantages
This fluid offers extended drain intervals due to its excellent stability to thermal cracking, preventing carbon deposit formation and maintaining heat exchange efficiency. It also boasts outstanding resistance to oxidation, ensuring long-term operational safety even with limited air exposure.
