TOTAL JARYTHERM DBT200℃ JARYTHERM® DBT Heat transfer circuit 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 mass (370 °C in the film) without air contact. JARYTHERM® DBT is used chiefly in the chemical ａnd plastics transformation industries (barrel extruders). SPECIFICATIONS  ISO 6743/12 class L-QD ADVANTAGES Long life time Working safety  Excellent stability to thermal cracking Authorizes lengthy periods 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.
