Closed circuits without air contact.
Main applications in the chemical and plastic processing industries.

International classifications

DIN 51522 class Q - ISO 6743-12 L-QD

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 resistance to oxidation, even with limited exposure to oxygen in the air. JARYTHERM DBT offers this characteristics.
