JARYTHERM® DBT
Heat transfer fluid
Synthetic heat transfer fluid, made from a blend of dibenzyltoluene isomers.
APPLICATIONS
Heat transfer installations
by fluid circulation
 Operating from 0°C to + 350 °C in the bulk (370 °C in the film) without air
®
contact. JARYTHERM DBT is mainly used in the chemical and plastics
transformation industries (barrel extruders).
SPECIFICATIONS
 ISO 6743/12 class L-QD-350
JARYTHERM® DBT successfully passes the following Thermal Stability tests
(1000h, 350°C):
 ASTM D6743
 DIN 51528
 GB/T 23800-2009
ADVANTAGES
Extended drain interval
Working safety
 Excellent stability to thermal cracking
Can be used for a long period without the formation of carbon deposits which
can foul the circuit. Preserves the heat exchange characteristics of the
installation.
 Resistance to oxidation
A thermal fluid must show good reistance to oxidation, even with limited
exposure to oxygen in the air. JARYTHERM® DBT offers this characteristics.
